The number of patients undergoing long-term hemodialysis and peritoneal dialysis is growing in the United States. To provide adequate emergent care to these patients emergency physicians must understand the alterations in normal physiologies present in these patients and how this may affect care. Cardiovascular disease and infection (especially Staphylococcus aureus sepsis) are the leading causes of death among dialysis patients. These patients are also subject to a significantly higher incidence of life-threatening electrolyte disturbances, particularly hyperkalemia and hypercalcemia, than the general population. Suicide, cardiac tamponade, intracranial hemorrhage, bleeding disorders, and bowel infarction are also much more frequent. The inability of dialysis patients to excrete drugs, metabolites, toxins, and fluids significantly alters their responses to common emergencies and should directly influence their care. Failure to recognize these differences in physiology may result in the use of standard forms of emergency therapy that may compound, rather than treat, the underlying disorder. Although most dialysis patients who come into an emergency department have conditions that can, and should, be managed by their nephrologist, the presence of a life threatening emergency requires prompt, appropriate therapy by the emergency physician.

Five hundred and thirty-three patients in the Oxford renal unit were reviewed to determine the incidence of infection in one calendar year. There were 310 patients who received dialysis, 53 with acute renal failure and 211 with chronic renal disease. Renal transplant patients were not included in the study. Apart from infections related to dialysis access, patients on maintenance haemodialysis or continuous ambulatory peritoneal dialysis developed few serious infections unless they had another disease causing suppression of immune function. A total of 97 urinary tract infections were seen; in patients with chronic renal disease not receiving dialysis the incidence of urinary tract infection was significantly associated with increasing uraemia, with diabetes, and with treatment with azathioprine or cyclophosphamide. In patients with acute renal failure, Gram-negative septicaemia and fungal infections were important causes of morbidity and mortality, but cardiovascular disease caused 42 per cent of the deaths unlike results from other series where sepsis has been by far the commonest cause of death.

We reviewed the hospital records and autopsy data of all deaths occurring at a Level I Trauma Center during a 1-year interval to determine the epidemiology of traumatic death in a regionalized system of care: 1,581 patients were admitted and 106 died (6.6%). Nonsurvivors (NS) differed significantly from survivors (S) in age, Trauma Score, Injury Severity Score, and probability of survival, but there was no difference between NS and S in scene time or transport time. Of the NS 91.4% died within 7 days; only 8.6% died after 7 days. Central nervous system (CNS) injury was responsible for 48.1% of deaths, followed by hemorrhage (36.8%) and cardiovascular disease (5.7%). Sepsis was responsible for 5.5% of deaths. Secondary brain injury was found at autopsy in 66% of patients dying of CNS injury. The relatively small number of septic deaths may be due, in part, to improvements in treatment associated with regionalization of trauma care. The frequency of secondary brain injury, despite rapid transport and evacuation of mass lesions, suggests that it may play a major role in the pathophysiology of CNS death occurring in a trauma system.

During the year 1985, 462 cases of septicemia were collected by SES group; 417 observations could be exploited. 73 patients died (17.3%). The statistical analysis of epidemiological and clinical data argued to factors correlated with high mortality rate: a shock, an acute respiratory distress syndrome, a pulmonary portal of entry lead to a high mortality rate. The fatal outcome increased with the age of the patients. A documented immunodeficiency (granulopenia, cytotoxic chemotherapy...), a previous broncho-pulmonary, neurologic or cardiovascular disease were factors of risk. The pulmonary or cutaneous localisations occurring within a septicemic phase were significantly related to death. Among fatal cases of bacteremia, 25% were Staphylococci, 25% Enterobacteria, 20% Pneumococci, 7% Pseudomonas. Pseudomonas, then Pneumococcus, then Staphylococcus bacteremias looks to have a worse prognosis. The more serious cases were prescribed several antibiotics, significantly much more than the mild cases. These results are compared with the results of former series; the main prognosis factors of actual septicemia are elicited in here.

Seventy-four patients have had a one-stage proctocolectomy for the management of Crohn's disease. Indications for operation were: acute colitis 28 per cent, chronic colitis 39 per cent, perianal disease 13 per cent, proctitis and perianal disease 8 per cent, bleeding 5 per cent, coexisting colonic malignancy 7 per cent. There were two hospital deaths (2.7 per cent), both associated with sepsis. Late deaths (n = 13) were most commonly associated with reoperations for recurrent disease (n = 3), cardiovascular disease (n = 4) and colorectal carcinoma (n = 1). Postoperative complications were principally associated with sepsis. Cumulative reoperation rates at 5 and 10 years were 19 and 24 per cent respectively. Recurrence was unrelated to the age of the patients, the duration of disease, or the presence of ileal disease at the time of colectomy.

Between March 1963 and December 1983, 324 renal transplants were performed in 273 veteran patients at the Veterans Administration Medical Center, Nashville, Tenn. Cadaver donors were used in 273 transplants, with an overall one-year patient survival of 72.5% and one-year functional graft survival of 50%. Twenty-four living-related transplants were performed, with an overall one-year patient survival of 89% and one-year functional graft survival of 75%. For analytical purposes the 20-year transplant experience was divided into five eras. One-year patient survival increased from 45% in era 1 to 84% in era 5, while functional graft survival increased from 45% to 70%. Death has occurred in 139 patients, with sepsis being responsible for the largest number of early deaths. Cardiovascular disease was responsible for most late deaths.

Factors predictive of a fatal outcome were retrospectively studied in 248 patients admitted with Staphylococcus aureus septicemia during 1965-1982, 78 of whom had endocarditis. 77 patients were intravenous drug addicts and 47 of them had endocarditis. 48 patients (19.4%) died. The fatality rate in addicts and non-addicts from septicemia was 0% and 17.9% and from endocarditis 8.5% and 61.3%, respectively. After analyzing clinical and laboratory data available early in the course of the disease 4 risk factors were found both in septicemia and endocarditis: age greater than or equal to 60 yr, pre-existing cardiovascular disease, prior hospitalization within 30 days of onset of illness, and neurological symptoms and/or signs. In addition, in endocarditis a platelet count before therapy less than 100 X 10(9)/l and left-sided involvement were unfavourable prognostic factors.

A fulminant case of endophthalmitis due to Clostridium septicum is described. The patient presented with spontaneous gas gangrene panophthalmitis, with early visual loss and an air bubble in the anterior chamber. Death ensued, and necropsy revealed changes consistent with severe arterosclerotic cardiovascular disease, a relationship not uncommon in patients with clostridium sepsis. This association as well as the histopathology of the globe are discussed.

The cases of 135 consecutive elderly patients 70 years old or older who had valve replacement and related surgical procedures from October, 1977, through April, 1982, were reviewed. There were 75 men and 60 women. The mean left ventricular ejection fraction was 50.16 +/- 5%. The overall operative mortality was 8% (11 patients). The early operative deaths were related mainly to cardiac failure, low cardiac output, sepsis, and renal and multiorgan failure. To assess the operative risk, these 135 patients were compared with 312 younger patients (less than 70 years old) who had undergone similar procedures during the same period. The operative mortality in this group was 5.2% (16). In-hospital complications included arrhythmia (13%), psychosis (7.4%), respiratory failure (6.7%), renal failure (6.7%), cerebrovascular accident (5.2%), myocardial infarction (4.4%), and reoperation for bleeding (2.2%). Wound dehiscence occurred in 1.5% of the patients, and pulmonary emboli and sepsis developed in 0.7%. Of these complications, only the incidence of cerebrovascular accident appeared to be more common in the elderly group (5.2% versus 2.8%), but it had no statistical significance (p = 0.18). A follow-up of 3,892 patient-months was completed in 98.4% of the survivors. There were 8 late deaths (6.4%). Six were related to the valve or to ongoing cardiovascular disease. Thirty-four patients subsequently required medical attention: 4 had bleeding because of the anticoagulant; 3 required a blood transfusion; and 27 were hospitalized. Six were admitted for related cardiac conditions and 7, for observation of other conditions; 14 underwent surgical procedures not related to the cardiovascular system.(ABSTRACT TRUNCATED AT 250 WORDS)

A survey has been made of 150 cases of acute renal failure (A.R.F.) seen between 1962 and 1981. The overall mortality was 43.3%. The patients ranged from 7 to 75 years old. The mean age of all the patients was 47.2 years old. The mean age of the patients seen between 1970 and 1981 was 58.1 years old, 20 years older than those seen between 1962 and 1969. Despite increasing expertise in management of the complications of surgical, medical, and obstetric disorders, and considerable technical advances in dialysis, there was no decrease in mortality over the 20-year period of survey. Many factors have been identified as having an adverse influence on prognosis, such as age of patient, surgical origin, and complications. Mortality rate was high in the patients over 71 years old, postsurgical group (55.6%), and hepatorenal syndrome group (92.3%). Five major complications had an adverse influence: septicemia (57.1%), respiratory infection (61.1%), cardiovascular disorder (46.3%), hemorrhage (59.6%), unconsciousness (62.2%), and hepatic dysfunction (56.8%). Between 1970 and 1981 the mortality in the patients dialyzed up to 3 times was 81.3%, compared with 26.5% in those dialyzed from 4 to 19 times (p less than 0.01). In the former group severity of the underlying disorder had an adverse influence on prognosis. Although the A.R.F. may be controlled in the earlier stages of illness, many of these patients die of overwhelming infection or other complications.
