Pathophysiology Early drowning literature stressed different hemodynamic and electrolyte effects on victims based upon the osmolality of the water aspirated low cost erectile dysfunction drugs cheap 100/60 mg viagra with dapoxetine free shipping. More recent literature has downplayed the effect of osmolarity of the solution aspirated and describes a common pathway leading to erectile dysfunction freedom book buy generic viagra with dapoxetine 100/60mg online similar degrees of injury for all submersions erectile dysfunction videos generic viagra with dapoxetine 100/60 mg overnight delivery. Later, progressive hypoxemia is related to the development of acute lung injury from surfactant disruption, abnormal alveolar function, alveolar collapse, atelectasis and intrapulmonary shunting. Acute apnea induced hypoxia precedes the sequence of cardiac rhythm deterioration which is marked by tachycardia followed by bradycardia, pulseless electrical activity, and, finally, asystole. Generally the sequence of drowning is a process which occurs in seconds to a few minutes, but in unusual situations, when associated with rapid hypothermia, the process can last for an hour. It has been postulated that hypothermia associated with drowning provides a protective mechanism that allows affected individuals to survive prolonged submersion episodes (Diving Reflex). Cardiopulmonary resuscitation Cardiac arrest from drowning is primarily due to lack of oxygen. This sequence starts with five initial rescue breaths, followed by 30 chest compressions, and continues with two rescue breaths and 30 compressions until: 1) return of spontaneous circulation, or 2) advanced life support becomes available. Successful outcomes after an extended period of advanced life support or until the patient has been rewarmed (if the patient has presented in asystole and hypothermic) have been reported. Any such maneuvers serve only to delay the initiation of ventilation and greatly increase the risk of emesis with an associated significant increase in mortality. Immobilization of the spine in the water is indicated only in cases in which head or neck injury is strongly suspected. Efforts to secure the airway, stabilize the circulation, insert a naso-gastric tube and rewarm the patient are key principles in initial resuscitation. In patients with a known seizure disorder, status epilepticus should be ruled out and anti-epileptic medications appropriately dosed. If the person remains unresponsive without an obvious cause, a toxicologic screen and computed tomography of the head and neck should be reviewed as soon as possible. It is usually best not to initiate weaning from mechanical ventilation for at least 24 hours, even when gas exchange appears to be adequate, as pulmonary edema may reoccur, necessitating reintubation and further morbidity. There is little evidence for the use of glucocorticoid therapy for reducing pulmonary injury and this practice should be avoided. In a series of hospitalized cases, only 12% of patients rescued from drowning had pneumonia and needed treatment with antibiotic agents. Early use of prophylactic antibiotics can lead to increased antibiotic resistance and aggressive multi-drug resistant organisms. Bronchoscopy is reserved for therapeutic clearing of mucus plugs or solid material, or deep cultures in the event of suspicion of pneumonia. If present, an early-onset pneumonia can be due to the aspiration of polluted water, 478 endogenous flora, or gastric contents. Once a diagnosis is made, empirical therapy with broad-spectrum antibiotics, covering the most predictable gram-negative and grampositive pathogens, should be started and definitive therapy should be substituted once the results of culture and sensitivity testing are available. Circulatory System: In the majority of patients who have been rescued from drowning, the circulation rapidly stabilizes and becomes adequate after attention to oxygenation, fluid resuscitation, and restoration of normal body temperature occurs. Infrequently, early cardiac dysfunction can occur in severe cases, and this cardiogenic component adds to the noncardiogenic pulmonary edema. No evidence supports the use of a specific fluid therapy, diuretics, or water restriction in persons who have been rescued from drowning in salt water or fresh water. Neurological System: Permanent neurologic damage is the most dreaded outcome in resuscitated persons after a drowning incident. Brain oriented resuscitation strategies have been recommended to improve neurological outcomes. The injured brain is extremely vulnerable to secondary insults and goals to achieve normal values for glucose, partial pressure of arterial oxygen, partial pressure of carbon dioxide, and cerebral metabolic oxygen consumption have been outlined. If the patient is neurologically impaired and normothermic, cooling should be started as soon as possible. In cases of neurologic impairment and hypothermia, a goal to maintain a target temperature at 32-34 °C for 12-72 hours is suggested. Provision should be made for appropriate sedation and the prevention of shivering if cooling is used. Clinical seizures or non-convulsive status epilepticus should be investigated and treated. Unusual Complications: Sepsis and disseminated intravascular coagulation are possible complications during the first 72 hours after resuscitation. Renal insufficiency or failure is rare, but can occur as a result of anoxia, shock, myoglobinuria, 479 or hemoglobinuria. Prognosis Reported survival rates for drowning victims vary from approximately 5-28%, although many of the survivors will have varying degrees of neurological impairment. The following features have been associated with death or poor neurological outcomes: 1. Prevention Every drowning signals the failure of the most effective intervention - namely, prevention. It is estimated that more than 85% of cases of drowning can be prevented by supervision, swimming instruction, technology, regulation, and public education.

During the period October 20th to erectile dysfunction caused by diabetes cheap viagra with dapoxetine 100/60mg with mastercard November 17th 1945 there have been four weekly publications in each of the four Zones of Germany of the said two notices in newspapers and over radio stations erectile dysfunction treatment yoga buy viagra with dapoxetine visa. The American erectile dysfunction books cheap generic viagra with dapoxetine uk, Soviet and British newspapers in Berlin have also carried thC notices. Furthermore, in pursuance of the order of the International Military Tribunal, the said notices were handed to the appropriate Military Authorities of each of the four Zones for reading in Prisoner-of-War Camps and for such other form of publication as local Commanders might think proper within their own discretion. Furthermore I have similarly ascertained that appropriate action has been taken by British Military Authorities for reading and posting in Prisoner-of-War Camps wherever practicable. I make this solemn declaration conscientiously believing the same to be true, and I declare that the information which I give therein has been obtained by me through official sources and from those persons whose duty i t is to give such official information. Willey, General Secretary, I have performed the following services in connection with publication, broadcast and posting of notices in the above entitled cause under order of the above entitled tribunal issued a t Nuremberg, Germany, on or about 18 October 1945: I 1. Hortin, Legal Division, Advance Headquarters, Control Commission for Germany (British Element), Berlin, on or about 23 October 1945, I arranged for the initial printing of 10,000 copies of the attached notice by the Ullstein Press, Berlin (Exhibit "1")- On 26 October 1945 I personally took delivery of 2,500 of the said notices and delivered them to Major E. The remaining 7,500 posters of the original 10,000 were delivered to Major Hortin for posting in the British. On or about 26 October 1945 I arranged for the publication, of 190,000 additional posters. Ninety thousand of these were personally delivered to me on 31 October 1945, and by me shipped to the Office of Military Government, U. Zone and the delivery of 40,000 to Headquarters, French Military Government a t Baden-Baden, Germany, for posting in the French Zone. A copy of the cable of instruction sent to Headquarters, Office of Military Government, U. To my personal knowledge the Office of Information Control Service, Office of Military Government for Germany (U. Fried, Executive Officer), relayed the attached notice to all German language newspapers and radio stations operating i n the U. I t is requested that necessary action be taken to post 2,500 copies of the two orders of the International Military Tribunal in the case of Hermann Wilhelm Goring et al. This request is in confirmation of arrangements previously made by Major Neumann and Lt. Pursuant to request 2,500 copies of the two orders of the International Military Tribunal in the case of Hermann Wilhslm Goring et al. Fried I have performed the following services or have been informed of the following facts in connection with the publication and broadcast of notices in the above entitled cause under order ef the above titled tribunal issued a t Nuremberg, Germany, on or about 18 October, 1945: 1. Forces, European Theater, I have been informed that the above mentioned notices were broadcast three times each between October 26 and November 8, 1945 (Exhibit I1 D). The general indictment of the 24 defendants and the Nazi organizations was broadcast a t 2015 on October 26, November 3 and November 8. The notification to Bormann to the effect that he would be tried in absentia if he did not appear personally for trial was broadcast at 2000 hours October 26, November 2 and November 8. All of these broadcasts originated a t Luxembourg and were relayed by Frankfurt, Munich, and Stuttgart. I further certify that this notice was also published by the form of pastings ordinarily employed by the military authorities in conveying information to the civilian population. I further certify that this notice has been delivered to the appropriate French authorities in charge of prisoners of war for publication in the German language wherever practicable in prisoner of war camps in which Germans are imprisoned, in such manner as the officers commanding such camps may decide. Certificate I hereby certify that announcement of the trial, by the International Military Tribunal of the criminal case of certain organi- zations was duly published in German in the Soviet Zone of occupation in Germany in all the newspapers under our control namely. Chief of Information Bureau, Soviet Military Administration in ~ e r m a n ~ s1 14 November 1945 - 17/11/45 A. Dissemination in the Russian Zone General Secretary, the International Military Tribunal, Nuremberg. Concurrently on these same dates it was published in Berlin in the following papers: "Tagliche Rundschau", "Berliner Zeitung", "Deutsche Volkszeitung", "Neue Zeit", "Der Morgen", "Das Vollr". Moreover, each week i t was published in the following provincial newspapers: "Volksblatt", "Sachsische Volkszeitung", "Volkszeitung", "Thiiringer Volkszeitung". I certify that i t has thereby received the widest possible dissemination throughout the British Zone. The General Secretary, International Military Tribunal, I certify that the notice to Martin Bormann that he is charged with having committed Crimes against Peace, War Crimes and Crimes against Humanity as set forth in an indictment which has been lodged with this Tribunal has been read in full in the German language once a week for four weeks over the radio in the British Zone, the first reading having been during the week of October 22, 1945, and that it has also been published in four separate issues of "Der Berliner", the newspaper published in the British sector of Berlin. As a result of the conclusions in these reports and my own observation, I suggest that the General Secretary recommend to the Tribunal that a committee of medical officers, representing each nation; be appointed by the Tribunal to proceed to Bliihbad for the purpose of giving Krupp von Bohlen a thorough examination and reportipg their findings to the Tribunal. Gustav Krupp von Bohlen was examined by me today, and the following findings are noticed. He suffered a n attack of cerebral thrombosis in 1942, which resulted in a temporary facial paralysis. He has no insight into his condition or situation whatsoever and is unable to follow or keep u p any conversation. I do not believe that subject can be moved without serious detriment to his health or that interrogation would be of any value due to his loss of speech and complete lack of any understanding. I n my judgment subject is not mentally competent to stand trial in a court of justice. Gustav Krupp von Bohlen und Halbach, born 7 August 1870, has been treated by me for many years; he was examined by me today. Since 1930 there has existed an arthrosis of the spine, as well as a hypotony which as far back as 1932 caused fainting fits. Since 1937 a rapidly increasing sclerosis of the vessels was to be noted which occurred in particular in the vessels of the brain. In 1939 a fleeting paralysis of the eye muscles made its appearance and passing disturbances of speech occured. In the spring of 1942, the patient suffered an apoplectic stroke on the left side, with facialisparosis and a distinct increase of reflexes on the entire right side. The cerebral disturbances of circulation have gradually grown worse despite treatments with medicaments. They manifested themselves first in the form of impaired memory and will power, indecision and general deterioration of intellectual faculties and increased to the point of definite depressions accompanied by apoplectic numbness and involuntary crying. In an automobile accident in December, 1944, the patient suffered a fracture of the nose bone and the skull basis and had to be treated for eight days in the Schwarzach Hospital at St. Since that time, his physical condition has also deteriorated, and several apoplectic fits have occurred as a consequence of multiple softenings of the brain with heart symptoms and striary syndroms. For approximately the last six months he has not been able to hold urine and stool. There can be traced an advanced emphysen in the lungs and a distinct myocardic impairment on the basis of a coronary sclerosis of the heart. The prognosis of the condition is definitely unfavorable, an improvement is not to be expected. The following history and physical examination of Herr Gustav Krupp von Bohlen und Halbach is submitted in compliance with a request from Mr. The information was obtained on the 19th and 20th of October 1945 when the patient was examined at his home at Bliihbach, Austria.

Each facility is identified throughout the remainder of this document by the letter corresponding to this table. The procedure must be known to potentially involve long fluoroscopy exposures over a stationary site, 2. The procedure must be performed sufficiently often at the participating facility to accumulate an adequate sample number for analysis, 3. On the basis of the above criteria the following procedures were selected for study: 1) Cardiac procedures: a. X ray systems Table 3 lists the fluoroscopic systems available for specific procedures at the facilities of each participant. Each participant collected data regarding their equipment, some details of which are provided in Appendix A. Physicians: Training in interventional cardiology Current guidelines of professional societies state that fellows in cardiology must undergo practical training in invasive cardiology. They specify the duration of training and how many procedures are required, depending on whether training is at the beginning of a career in interventional cardiology or just a part of the basic knowledge . During the period considered, five cardiology fellows attended the catheterization laboratory for periods of five to six months and they participated in 819 diagnostic procedures (mean 168 ± 76, minimum 88, maximum 276). Cardiac catheterization was performed with Judkins technique in 90% of cases in both groups and in 10% by radial or brachial approach. At the beginning, participation of fellows was limited to venous and arterial site puncture and manipulation of catheters at the right site of the cardiovascular system. As their experience grew, the fellows were allowed to perform left heart catheterization first and eventually to engage the coronary ostia. A staff member was beside them, scrubbed in the majority of cases, but in the last part of the training (typically the last two months) they were allowed to work with supervision only, in selected patients. Patients examined by fellows and staff were comparable for sex (69 vs 70%), age (66±11 vs 66±10) and body mass index (26. Patients in F group were more likely to undergo right heart catheterization (27% vs 17%, p0. Slightly different instrumentation was used by each center for these purposes due to their different resources. Dosimetric techniques employed for the examinations by the centers are given in Table 4. Both terms apply to the integral over the beam area of the free-in-air air kerma and are commonly measured in units of Gy. In-field variations in beam intensity, due for example to the heel effect, are not taken into account. So, even if area at the skin is known, there is no possibility to determine the average entrance air kerma at a single site on the skin surface. The entrance area of the beam can be ascertained from the film but some accounting for beam reorientation during the procedure is necessary. Since the X ray beam is mainly bremsstrahlung, only an estimate of this factor is possible. This factor depends on the area of the beam and the quality of the bremsstrahlung radiation. This method was used for neuroradiological, biliary and hepatic examinations by some centers. The film was placed on the table underneath the patient and centered as closely as possible to the area of the skin expected to receive the highest dose. Portal film has the advantage that the readout is directly related to the radiation that enters locally on the skin, it includes backscatter, and it is independent of beam reorientation. Said another way, error in skin dose estimate due to beam reorientation and back scatter radiation is eliminated for this dosimetry medium, except in cases where the film does not intercept the beam, such as with a lateral beam. The disadvantage is that the film must be processed for readout and provides no readout during the procedure. Calibration and quality control to assure a stable readout are also time-consuming. This allows for an estimate of skin dose if the distance from the chamber to the skin is accurately recorded. Radiochromic media Radiochromic dosimetry media (commonly referred to as "films") can be handled in normal lighting conditions, respond nearly immediately to exposure to radiation, and they require no chemical processing since they are self-developing. They are used to measure absorbed dose and to map radiation fields produced by X ray beams in a manner similar to that of portal film. As such, radiochromic media have the same advantage of locally specific dose monitoring without error resulting from beam reorientation or backscatter. Radiochromic film can be examined during a procedure if there is a need to obtain an estimate of skin dose. The degree of darkening is proportional to exposure and can be quantitatively measured with a reflectance densitometer. There does exist a gradual darkening of the film with time and darkening is usually maximum within 24 hours. However, the amount of darkening within the period immediately following the initial exposure is not large and does not interfere with the ability to use it for skin dose guidance during a procedure as long as this phenomenon is understood and taken into account. A limited quantity of radiochromic films was distributed to the centers to be used nearly exclusively for cardiac examinations. For cardiac work, films were placed on the table under the patient pad in such a way that the most heavily exposed parts of the body were covered by the film. When used in the manner described, the film darkening includes backscatter, and beam reorientation and field non-uniformities are recorded. The only correction factor necessary is the conversion from entrance air kerma at the skin to absorbed dose in the skin. The limitation of this technique is that the highestdose area of the skin must be known a priori. Since calibration is usually in terms of air kerma, the usual correction factor of 1. The scintillator has a dimension on the order of a millimeter and is bonded to the tip of a fiber optic cable. The other end of the cable is connected to a light sensitive meter that cumulatively records the light output and converts the light signal into an electronic signal which is calibrated for display in units of mGy. An additional disadvantage is that the fiber optic cable must be strategically positioned during the procedure in order to avoid interference with the rotating gantry of a c-arm fluoroscope. Further, the monitor base is not well shielded and must be kept away from the radiation area to avoid a false readout. Every center reported the dose as measured with their locally used reference dosimeter. In order to assure agreement on the processed doses among the participants, an intercomparison of the calibration of the radiochromic film was performed. These pieces were irradiated by X rays in steps of about 100-200 mGy covering an interval between 0 and 5 Gy.

Work-based experience this is the apprenticeship model where there is gradual reduction in supervision according to increasing competence as judged by trainers. More responsibility is taken by the experienced trainee in performing the procedures that form the case mix of his/her training, but always with the appropriate level of supervision. It is desirable to have a stratification of escalating competencies and a formal process of assessing these during training.

Selection of studies with sound methodology is done from a collection of all studies on the topic found after an extensive literature search. These studies are reviewed, assessed for quality and the results are summarised with reference to specific predetermined criteria set to answer the question. Meta-analyses Examines thoroughly all valid studies in literature on the study topic, uses the data from all of them as a single large data which is then used in accepted statistical models to give results. Observational studies Case studies and reports Are presentation of a series of cases or some cases with similar clinical problems and their outcomes after a particular therapy. This has low statistical evidence but can form the basis or stepping stones for future trials. Case control studies It is a type of observational study in which two existing groups differing in outcome are identified and compared on the basis of some supposed cause. Cohort studies (retrospective cohort or historical cohort) They are generally prospective studies. These are comparative studies of two groups in which one receives the treatment compared with another that receives another treatment. Cross sectional studies A study that examines the relationship between diseases (or other health-related characteristics) and other variables of interest as they exist in a defined population at one particular time.

Principles of combination chemotherapy to reduce the occurrence of drug resistance. Regime types by intent: induction, consolidation, adjuvant, neoadjuvant and maintenance. Drug side effects Understanding of key common toxicities for chemotherapy generally and more detailed toxicity profiles for agents relative to their field of specialisation and action is important. Some chemotherapy drugs induce leukopenia, therefore it is important to know when to avoid performing procedures and which is the best window in which procedures can be performed on patients receiving this type of chemotherapy. Radio-resistance Certain molecular markers suggest relative radio-resistance: hypoxia, P21 and P53 mutations and a low proliferation rate. Types of radiotherapy External beam May be delivered as electrons, photons or protons.

Immune reconstitution disease associated with parasitic infections following initiation of antiretroviral therapy. Two doses of varicella vaccine should be given, starting as early as 12 months of age, with an interval of 3 months. VariZig is given intramuscularly at the recommended dose of 125 units/10 kg, up to a maximum of 625 units. Therapy initiated early in the course of the illness, especially within 24 hours of rash onset, maximizes efficacy. Prior to the universal administration of varicella vaccine, approximately 4 million cases of varicella occurred annually in the United States. In the United States, the incidence of varicella and its associated morbidity and mortality have decreased by 88% because of universal vaccination. However, because most pregnant women have varicella immunity, varicella complicating pregnancy is unusual. In mothers who develop varicella 5 days before to 2 days after delivery, the attack rate for infants is approximately 20%, and mortality, before the availability of antiviral therapy, was approximately 30%. Varicella can be associated with a brief prodrome of malaise and fever, followed by the appearance of skin lesions that are more numerous on the face and trunk than on the extremities. The lesions appear in three or more successive crops over approximately 5 to 7 days. They evolve quickly (in about 24 hours) through macular, papular, vesicular, and pustular stages, culminating in crusts. A rapid decrease in visual acuity, or occurrence of red eye or eye pain, should prompt an immediate consultation with an ophthalmologist for diagnosis and specific therapy. Laboratory diagnostic methods are required for atypical presentations, prolonged course of disease, and non-response to therapy. Optimal sensitivity requires obtaining cells from the base of a lesion after unroofing a fresh vesicle. Antiviral therapy is rarely required, and skin lesions usually clear in 3 days to 5 days without treatment. This compares favorably with the efficacy of the vaccine in healthy children (after one dose) and in children with underlying leukemia (after two doses), where an efficacy of 80% to 85% was observed for prevention of clinical infection. When passive immunization is not possible for severely immunocompromised patients, some experts recommend oral acyclovir for post-exposure prophylaxis (see below). Post-Exposure Antiviral Prophylaxis Several small studies suggest that post-exposure prophylaxis with oral acyclovir often prevents or attenuates varicella in healthy children,50-52 although this approach is predicated on adequate specific immune responses developing in the exposed child during the incubation period. When passive immunization is not possible, some experts recommend prophylaxis with oral acyclovir 20 mg/kg body weight (maximum dose 800 mg), administered 4 times daily for 7 days, beginning 7 days to 10 days after exposure. In immune competent children, new lesions can continue to appear for 72 hours after initiation of acyclovir and crusting of all lesions may take 5 days to 7 days. Progressive outer retinal necrosis evolves rapidly, and despite aggressive therapy, the prognosis for visual preservation is poor. Valacyclovir is a prodrug of acyclovir with improved bioavailability, which is rapidly converted to acyclovir after absorption. Sufficient information exists to support the use of valacyclovir in children (especially given its improved bioavailability, which is two- to three-fold that of acyclovir) at a dose of valacyclovir 20 to 25 mg/kg body weight administered two to three times a day. Since acyclovir is excreted primarily by the kidneys, dose adjustment based on creatinine clearance is needed in patients with renal insufficiency or renal failure. If possible, virus isolation should be attempted so that susceptibility testing can be performed to confirm drug resistance. As this may be difficult to arrange and will involve significant delay, the decision to change therapy is often based on clinical observations. Foscarnet has significant nephrotoxic potential; 30% of patients experience increases in serum creatinine. Foscarnet also causes serious electrolyte imbalances (including abnormalities in calcium, phosphorus, magnesium, and potassium levels) in many patients, and secondary seizures or cardiac dysrhythmias can occur. Infusing foscarnet with saline fluid loading can minimize renal toxicity, and infusion through a central venous catheter can prevent thrombophlebitis. Doses should be modified in patients with renal insufficiency (see package insert).

Step two of the Uniform Anatomical Gift Act states that consent is required before organs may be removed erectile dysfunction pump medicare buy 100/60mg viagra with dapoxetine visa. Although legally appropriate to erectile dysfunction talk your doctor viagra with dapoxetine 100/60mg cheap proceed with organ procurement in the setting of first-person consent erectile dysfunction drugs lloyds discount 100/60 mg viagra with dapoxetine fast delivery, it is strongly advised that the family be closely involved in the discussion to mitigate any potential conflicts. If appropriate consent is obtained, critical care professionals should begin to transition the goals of care. Any potential organ donor has the right to comfort measures and all attempts should be made to provide this support, whether or not they may become donors. Additionally, support should be provided to the families of potential organ donors, including pastoral care, social work, and palliative care staff. A multidisciplinary approach to the end-of-life care for potential organ donors often provides the best care for all parties involved. As medicine evolves, the opportunities for potential organ transplantation continue to increase. Organ donation can be a wonderful gift allowing those at the end of their life to extend the lives of others and can offer families the closure that something positive has come from their loss. It is important to understand that not all patients and families will share these sentiments. After you have explained the risks and benefits of chemotherapy to a patient recently diagnosed with leukemia, she has decided not to proceed with chemotherapy and has instead said that she wishes to spend the rest of her days at 58 home with her family. A 68-year-old man has suffered a massive heart attack and is now intubated and on full support including an intra-aortic balloon pump. On exam, he has positive corneal and gag reflexes, but his imaging studies reveal devastating neurological injury. He had previously expressed to his wife that he would not want to be "on a breathing machine. This law was enacted to facilitate the process of organ procurement for donation: a. These decisions may be difficult, particularly when they involve end-of-life discussions or the rationing of medical care. Institutions/physicians confront complex questions when formulating local triage guidelines: 1. Organizational Guidelines National and international organizational guidelines provide a framework for answering these questions. The model separates patients into 4 groups, from highest priority (priority 1) to lowest priority (priority 4). Priority 2: patients who require intensive monitoring and may potentially need immediate intervention 3. Priority 3: unstable patients who are critically ill but have a reduced likelihood of recovery because of underlying disease or nature of their acute illness 4. There is a tradeoff between the simplicity and the precision of the risk estimates provided by these scoring models. Physician judgment has been shown to be a valid estimate of patient mortality risk, and may even exceed the performance of clinical scoring models. They are emotionally taxing, contribute to provider burnout, (17) and are susceptible to bias. These teams may diffuse the ethical responsibility from a solo practitioner and be a feasible alternative model in settings where physician intensivists are unavailable. While objective and subjective tools are available, they must be adapted to local contexts and triage models must remain faithful to the basic tenets: equity, ethics, and transparency.

After her airway is secured, an arterial blood gas reveals severe hypoxia and acidosis. A brain natriuretic peptide laboratory result indicates decompensated heart failure. The expected growth rate is 1% per year, indicating that critical care delivery models that include telemedicine support will be more common than the standard bedside intensivist-led programs. In addition, an aging population with an increased need for critical care services, coupled with a limited supply of trained intensivists and critical care nurses has led to a shortage of critical care practitioners. Most existing studies are before-after studies limited to single centers that lack control groups. The single page shows a brief patient description, list of pertinent diagnoses, treatments in progress, a graphical vital signs trend, list of lines, tubes, drains, and antibiotics (including start dates), mechanical ventilation data, most recent lab trends, as well as intake/output status. In fact, most housestaff welcome the 67 assistance of a critical care specialist to assist in management, especially during off-hours when the bedside attending physician is either asleep or off the unit. Survey studies have been sent to residents and fellows to gauge the level of acceptance at various teaching institutions. Specific advantages cited include assistance with ventilator management, initial management of an unstable patient, supervision during situations requiring advanced cardiac life support, management of acute changes in patient status, and interpretation of diagnostic tests. The fear is that because the providers are not at the bedside, their position will be less defensible in court. Conclusions Telemedicine in critical care is poised to play a major role in the expansion of critical care services to hospitals that otherwise would not have access to intensivists. Technological advances now permit an intensivist to remotely interact with a patient thousands of miles away and to assist on-site staff in clinical decision making. As telemedicine in critical care continues to expand, its effects on patient outcomes and its medicolegal implications can be more 68 thoroughly studied.

Use the same initial or starting velocity for model used to why smoking causes erectile dysfunction purchase 100/60mg viagra with dapoxetine visa construct seismic tomography 2. Benchmarks for seismic velocity measurement should be at a sufficient distance from construction site. The entire cavity can be filled or low slump grout columns can be constructed to reinforce the roof of the void. Due to its solubility in water, limestone tends to erode and dissolve over time, thus forming in-situ cavities. These phenomena, also known as "sinkholes" can potentially cause the ground above to collapse or sink if they migrate to the surface. The rheology of the grout prevents it from flowing through the network of caverns which can exist in limestone. In this way, localized filling and stabilization of an area can be accomplished and sinkholes can be prevented. Depending on the design of the grout and the nature of the site, this approach can be adopted also in flowing water conditions (Bruce et al. Similar to other forms of grouting, the drilling and grouting should be considered an extension of the exploration program, while also remediating the problem. The advantages of bulk void grouting are as follows: · · · · · · Low cost per unit volume of materials when using inexpensive fillers Minimum disturbance of existing surface structures Strength of grout can be tailored to fit the in-situ condition Essentially yields full roof contact Grout can penetrate all locations without fear of the grout flowing, settling or being washed away Effectiveness can be verified 2. The second is containing the grout within the zone to be stabilized, although low slump grout "barriers," accelerated grouts, and grout-filled fabric forms have been used to minimize this problem as illustrated in Figure 8-12. The information studied for void filling should include historical as-built data on mine and tunnel projects. Historical mine maps are an invaluable source of information, but must be related to contemporary land forms or structures. These can often be supplemented by visual surficial or underground assessments, where man-access is practical and safe. Assessment of karstic terrains is often more difficult, and may involve intensive exploration drilling, usually supplemented by a variety of geophysical. Great variability in ground conditions may be anticipated between adjacent boreholes in karst. As a basis for design, therefore, the lateral and vertical extent of the voids or collapsed zones must be determined together with an indication of the groundwater regime, and, in particular, if the water is flowing, where it is flowing, and at what velocity and rate. In general, it is not uncommon to identify projects involving the drilling of several hundreds of holes to depths 8-50 of greater than 300 feet and the injection of a variety of grouts formulated from hundreds of thousands of tons of materials. Void filling usually encompasses one or more of the other grouting techniques and so the materials utilized in void filling vary considerably. The sections corresponding to these different grouting techniques should be reviewed when considering a void-filling project. When filling scoured zones with concrete filled tubes or bags, a fine aggregate concrete (structural grout) is recommended. Typical Range of Material Mix Proportions for Void Filling Applications Material Cement Fly ash Sand Water Mix Proportions Mix Proportions (lb. However, if clay or other erodible material is present as infill, then it is best to remove as much of this material as possible prior to grouting. Clay trapped in grouted karstic cavities can be removed if subjected to prolonged differential head. It is important to realize that the extent of a cavity is unknown after penetration by just one grout hole and even the thoughtful implementation of appropriate geophysical techniques 8-51 may not yield conducive information. Sometimes, it may be necessary to use intermittent grouting, which is the process of injecting grout in the hole and then waiting several hours before injecting additional grout. In practice, the maximum quantity of grout to be injected varies from about 30 to 1,000 cubic feet or more per injection period. A limit may also be placed on the maximum amount of grout to be injected into a single hole. When grout injection refusal is reached, it is assumed that grout has filled at least the portion of the cavity penetrated by the grout hole. Additional grout holes are then drilled and grouted until the desired results are achieved in a split spacing sequence. If pressures fail to build up or the cavity is too large to grout in this manner, grouting should continue with a grout curtain placed to control the flow of grout from the cavity, or radically different materials and methods should be considered. Additional exploration, consultation, evaluation, and design of treatment can then take place without delaying the project. These measures may call for specialized grouting procedures or materials, such as foaming agents or accelerators, positive cutoff diaphragms or formed concrete wall, hot bitumen, additional excavation, grout filled bags, or some other solution. Grout hole spacings and locations will be dictated by the site conditions, but holes on a final grid spacing of 10 feet or less are not unusual for "tightening" purposes. Borehole cameras are available that can be placed in adjacent drill holes to observe and verify that the injection of grout is satisfying project requirements. The cost for supplying, mixing, and injecting the grout normally ranges between 57 to $153/cubic yard. A review of costs for bridge scour repair using concrete fabric forms from 1968 to 1976 in Pennsylvania indicates a range of $230 to $765/cubic yard (Okonkwo et al. The third and fourth case histories presented in this section describes the use of bituminous grout and cemented paste for mine backfill. Karstic limestone is the major terrain type in the county, which undergoes formation of several sinkholes due to erosion of the sandy overburden into voids in limestone. The County, in collaboration with an Engineer-Contractor team developed a rapid response system to investigate, remediate, and manage sinkhole grouting projects. Costs for investigation, pipe installation, and grouting were established by the County for selecting the team to eliminate delays. Typical layer profile in this area of Florida consists of 30 to 60 feet of sand or clayey sand, followed by a 5 to 20 feet stratum of highly plastic clay and a very porous weathered limestone layer underneath as shown in Figure 8-13. Remediation of sinkholes in Florida was typically accomplished by installing grout pipes within and around the depression/drop-out, and pump a sand/cement/fly ash grout in the soil above the sinkhole. The purpose of grout is to prohibit vertical seepage and compact soils disturbed by the sinkhole formation and fill any open voids left in the soil. Sinkholes were identified from loss of drilling fluid, which is indicative of vertical seepage that causes soil erosion into limestone. Grout holes for the sinkhole remediation project were drilled into the limestone layer at 5 feet from each other in three rows extending beyond the sinkhole limits. The treatment required 13 pipes for the sinkhole at depths ranging from 46 to 77 feet. Cost of grout for a highway sinkhole remediation project in 2003 that required 408 cubic yards of grout was $45,000, which was about two-thirds of the total project cost. The foamed grout strength was measured in the laboratory as 290 psi as compared to ~4000 psi of a typical grout, but pumped relatively easily at low pressures. The quarry geology is heavily karstic with several large cavities, and the hydraulic gradient increased with depth of 8-54 excavation. The source of inflow was determined to be the Mississippi river located about 3280 feet from the quarry from which two conduits measuring almost 20 Ч 30 feet, which were centered at 250 feet and 305 feet below grade, carried a 35,000 gallons/minute inflow to the quarry floor, which was more than 330 feet below grade as shown in Figure 8-14.
