The survival from acute renal failure requiring renal replacement therapy was studied in 90 critically-ill patients admitted to an intensive care unit. Mean age (+/- SD) was 51 +/- 14.6 (range 17 to 81) years. Mechanical ventilation was required in 88 patients and 71 patients received total parenteral nutrition. Thirty-three per cent of patients left the intensive care unit alive and 24 per cent survived to leave hospital. Final survival was 20 per cent in medical patients (n = 49), 29 per cent in surgical patients (n = 38) and 100 per cent in obstetric patients (n = 3). Hypotension, requirement for inotropic support, oliguria and sepsis were all associated with a poorer prognosis. The mode of renal replacement therapy did not affect survival, but additional haemodialysis was required in 33 of 65 patients treated by continuous arteriovenous haemofiltration but none of 22 treated with continuous arteriovenous haemodialysis (p less than 0.001). APACHE II score was calculated for 87 patients. Mean APACHE II score was 26.1 +/- 6.9 (range 14 to 44). APACHE II score on admission predicted the likelihood of survival well. No patients with a score of more than 40 survived, compared to 40 per cent of those with scores of 10 to 19. Pre-existing organ insufficiency or immunosuppression meriting a CHE score of 5 was associated with a very poor survival (1 of 30 patients). APACHE II score is a reliable indicator of severity of illness and likelihood of survival in critically-ill patients with acute renal failure. The widespread adoption of APACHE II scoring for patients with acute renal failure requiring intensive care would facilitate medical audit and comparison of studies from various centres.

The pattern of acute renal failure in third-world countries is changing albeit at a slower pace compared to that in developed countries. Of the 1862 patients with acute renal failure requiring dialysis between 1965 and 1986 in a north Indian centre, 60, 15 and 25 per cent were related to medical, obstetrical and surgical conditions respectively. Among the medical patients, diarrhoeal diseases which caused 23 per cent of the total number of cases of acute renal failure in the period 1965 to 1974 caused only 10 per cent in 1981 to 1986. In the same period, acute renal failure due to sepsis and drugs increased while that due to copper sulphate poisoning and intravascular haemolysis showed a downward trend. Obstetrical acute renal failure declined from 22 per cent in 1965 to 1974 to 9 per cent during the period 1981 to 1986. This decline was chiefly due to a fall in cases of septic abortion, puerperal sepsis and postpartum haemorrhage. Surgical acute renal failure increased from 11 per cent during the period 1965 to 1974 to 31 per cent in the 1980s, predominantly due to an increase in patients with obstructive uropathy. Despite these favourable trends, the pattern of acute renal failure in the third world continues to be different from that in the developed countries.

A 38-year old quintipara with an unremarkable medical history suddenly complained of nausea during delivery, became pulseless and cyanotic, and lost consciousness. The ECG showed evidence of tachycardia, ventricular extrasystoles, and right-ventricular strain. Within 30 min there were also hemorrhage and a consumption coagulopathy (Table 1). Kerato-hyaline cell material was found in central-venous blood. Following cardiopulmonary resuscitation, emergency cesarean section, hemotherapy (Table 2), and intensive care (acute renal failure, ARDS, sepsis) the patient was able to be released with no permanent sequelae. The etiology, epidemiology, and clinical aspects of amniotic fluid embolism are discussed.

The best definition of risk factors for renal injury, irrespective of the aetiological agent, comes from observations in patients with acute renal failure. From such observations, two subdivisions have evolved, i.e., acute insults and host risk factors. Acute renal insults include: hypertension, sepsis, use of nephrotoxic drugs (e.g., aminoglycoside antibiotics and contrast media), haemoglobinuria or myoglobinuria, liver disease and extracellular volume depletion. Host risk factors include: advanced age, hypertension, gout and hyperuricaemia, diabetes mellitus, chronic renal failure and use of diuretics. Furthermore, the mechanism of acute renal injury can be correlated with different risk factors: for a tubular toxic agent, acting either directly on the cells or haemodynamically, a dose-dependency is characteristic; while for immunologically mediated injury, genetic predisposition is more important. The identification of risk factors for chronic toxic injury is confounded by the possibilities of multiple episodes of subclinical renal injury, the distinct possibility that a major component of the ageing process may be a loss of renal reserve, and a progressive body burden, of, e.g., cadmium, which may deplete intrinsic protective mechanisms. However, clinically relevant risk factors can alert the clinician to exercise additional caution when prescribing medications that are potentially nephrotoxic. Such factors include dehydration, pre-existing renal disease, age, co-existing diseases that cause renal ischaemia, gender, concomitantly administered drugs, and electrolyte abnormalities.

Oxidative metabolism of polymorphonuclear leukocytes (PMNs) in uremic patients is enhanced due to unknown serum or plasma factor(s) which are removed during hemodialysis. Respiratory burst activity is diminished in both PMA-stimulated and unstimulated states compared to healthy controls. Hemodialysis treatment normalizes stimulated hydrogen peroxide production and decreases unstimulated hydrogen peroxide production. Several authors found that resting and stimulated chemiluminescence (CL) during hemodialysis correlate with complement activation, whereas other authors describe the development of CL using dialyzer membranes with only mild anaphylatoxin formation. Alterations in PMN carbohydrate metabolism in uremic patients improve during HD. These alterations may be responsible for disturbances in phagocytosis. Degranulation during HD also occurs in the absence of complement activation. Calcium channel blockers decrease activation of PMNs when dialyzers with only little anaphylatoxin formation are used. Acute renal failure and sepsis induce activation of PMNs. Hemodialysis with membranes made of cuprophan leads to further activation of these PMNs and may contribute to granulocyte dysfunction.

All patients (n = 1308) admitted to a multidisciplinary intensive care unit (ICU) during a 5-year period (1979-83) were followed prospectively. The in-unit mortality was 18% and the in-hospital mortality (mortality during ICU-stay plus mortality during the ensuing hospital stay) was 29%. Increasing age was associated with increasing in-hospital mortality, up to 40% mortality rate in patients aged 80 years and older. Using multiple logistic regression analyses, prognostic factors for mortality were identified. Risk factors for death in the ICU included age, cardiovascular diseases, sepsis, adult respiratory distress syndrome and acute renal failure. Cancer did not appear as a risk factor. The mortality during the ensuing hospital stay, however, was significantly influenced by cancer as well as the aforementioned risk factors. When controlled for severity of illness, expressed by the level of organ system failure after 48 h of ICU treatment, only sex, sepsis and severity of illness showed significant influence on the mortality in the ICU, and only sex and severity of illness significantly influenced mortality during the ensuing hospital stay after discharge from the ICU.

The use of aminoglycosides and cephalosporins is fairly often complicated by acute renal failure (ARF), particularly so if overdoses are used and baseline renal function is impaired. The course of ARF and outcome of treatment have been analyzed in 51 patients. ARF was caused by a nephrotoxic effect of aminoglycosides, cephalosporins or a combination thereof (ARF, type A) in 30 (58.8%) patients, and a combination with other factors (hypotension, arterial hypertension, sepsis) in 21 (41.2%) patients (ARF, type B). Nephrotoxic effect was more commonly produced by a ceporin-gentamicin combination (in 34 (66%) of 51 cases). Nineteen (55.8%) of the 34 patients died, in spite of extracorporeal detoxication treatment (peritoneal dialysis, hemodialysis), which way be attributed to a severe original condition (mostly, due to severe sepsis, original functional renal insufficiency, etc.) rather than the nephrotoxic effect of antibiotics. Hyperazotemia without marked oliguria is a specific feature of ARF, induced by nephrotoxic action of antibiotics. Preventive principles are proposed.

Size limitations and technical barriers prohibit the use of many conventional mechanical circulatory support systems for postcardiotomy ventricular dysfunction in pediatric populations. Extracorporeal membrane oxygenation (ECMO), frequently used to treat neonatal respiratory failure, can provide cardiac support and is effective treatment of postoperative myocardial failure in children. From 1981 to 1987, 10 patients aged 2 days to 5 years were maintained on ECMO for 15 to 144 hours (mean duration, 92 +/- 16 hours) after cardiotomy. Operative procedures included repair of tetralogy of Fallot (2 patients), closure of a ventricular septal defect (2), the Senning procedure for transposition of the great arteries (1 patient), repair of interrupted aortic arch with closure of a ventricular septal defect (1), repair of a partial atrioventricular septal defect (2), closure of a ventricular septal defect with excision of an anomalous muscle bundle (1), and the Fontan procedure (1). Venoarterial ECMO was established in all 10 children. Six patients underwent transthoracic right atrium-ascending aorta cannulation, 3 had right internal jugular vein-right common carotid artery cannulation through a cervical incision, and 1 had right internal jugular vein-left axillary artery cannulation. Eight of the 10 patients were successfully weaned from ECMO, and 7 are long-term survivors. There were 3 deaths; 1 was caused by cardiac and acute renal failure complicated by sepsis two days after decannulation, another occurred 19 days after atrioventricular septal defect repair, and 1 was caused by massive pulmonary hemorrhage. Major hemorrhage developed in 3 patients while on ECMO; 2 required premature decannulation for mediastinal bleeding from operative sites and ultimately survived, and 1 died of respiratory failure as a result of endobronchial bleeding. We conclude that the use of ECMO in pediatric populations for transient postoperative ventricular dysfunction improves survival with limited overall morbidity.

An immunologically normal 70-year-old male developed fever and disturbance of consciousness after aortocoronary bypass; this was followed by diarrhea, systemic erythroderma and granulocytopenia. He died as a result of sepsis and acute renal failure. The skin biopsy showed basel vacuolar degeneration, epidermal eosinophilic necrosis and invasion of T-lymphocytes. The autopsy showed necrotic small interlobular bile ducts, severely hypoplastic bone marrow and widespread necrosis of lymphoid tissue. Based on these clinicopathological findings, we made a diagnosis of graft-versus host reaction after transfusion.

We reported a case of halothane-induced fulminant hepatitis with acute renal failure which developed 6 days after reexposure to halothane. The patient was a 58-year-old female. She had a history of liver dysfunction after exposure to halothane 6 years previously. She had surgical treatment of clubfoot under halothane anesthesia in other hospital. Preoperative physical examination and laboratory data were normal. On the 6th post-operative day she abruptly developed high fever and general fatigue. Next day, she was transferred to our hospital. At admission, fulminant hepatitis complicated with acute renal failure was diagnosed with severe liver and renal damage. She was immediately treated with plasma exchange, glucose-insulin therapy, and hemodialysis. Serum transaminase level returned to normal value within a week. However, despite repeated hemodialysis, renal function did not improve, and she died of P. aeruginosa sepsis on 28th day after the operation. It may be suggested that in this patient hypersensitivity to halothane has persisted during the six years.
