Delayed spontaneous rupture of the urinary bladder following augmentation enterocystoplasty is a serious life-threatening complication of uncertain etiology. Multiple factors are believed to contribute to the mechanism of bladder perforation. Ruptured augmented bladders share a common urodynamic pattern of high leak point pressure of the urethra, with sensory and mechanical tolerance of high filling pressure. This combination seems to be the main predisposing factor for spontaneous perforation. Other risk factors, including catheter trauma during intermittent self-catheterization, urinary retention due to mucus retention or noncompliance with the catheterization protocol, chronic infection, and decreased sensation of bladder filling, may play roles in the mechanism of rupture. Clinically, patients present with sepsis, abdominal pain and distension, ileus, fever, oliguria and peritoneal irritation. The diagnosis is made on low pressure cystography, although failure of cystography to demonstrate extravasation is not unusual. Aggressive surgical treatment consists of immediate exploration, primary repair of the perforation, drainage of the perivesical space, suprapubic cystostomy and broad-spectrum antibiotics. Longterm management includes a strict intermittent catheterization schedule, anticholinergic therapy and urodynamic evaluation. Failure to achieve a low pressure storage reservoir by conservative means entails an increased risk of recurrent perforation. In such cases further surgical intervention should be considered. We present a 21-year-old paraplegic man 5 months after augmentation enterocystoplasty who required operation because of spontaneous rupture of the augmented bladder. Spontaneous delayed rupture of the bladder should be considered in the differential diagnosis of acute abdomen in patients after augmentation enterocystoplasty. Early surgical treatment and subsequent monitoring of the low pressure reservoir are recommended.

Peritoneal dialysis was required in 20 (12.8%) of 156 neonates and infants for acute renal failure following open heart surgery using cardiopulmonary bypass. Cardiac diagnosis was TAPVD (7 cases), PA with IVS (2), ECD (2), coarctation of the aorta with VSD (2) and other cardiac malformations (7). The indication for dialysis was oliguria of less than 1.0 ml/kg over 4 hours resistant to volume repletion, inotropic agent and diuretics. Peritoneal dialysis was performed using dialysis catheter and glucose containing dialysis solutions. The mean predialysis BUN and serum creatinine were 30.4 mg/dl and 2.7 mg/dl respectively. The highest serum creatinine during dialysis was 4.5 mg/dl, and all but one patient had BUN level of under 100 mg/dl. Dialysis with glucose containing solution could allow sufficient fluid removal as a result, fluid overload was restored. Plasma protein and electrolytes balance were corrected within 48 hours. Two neonates and 4 infants survived. Thirteen patients died on dialysis: nine of those deaths were related to low cardiac output, 2 death were attributable to respiratory insufficiency, and 2 cases died due to sepsis. One infant died of an unexplained cardiac arrhythmia after renal failure had been improved. It is concluded that peritoneal dialysis is beneficial in neonates and infants who become oliguria following open heart surgery.

In a retrospective analysis of 2110 admissions to the pediatric intensive care unit, 564 cases of septic shock were identified (26.7% of the total admissions). Septic shock was defined in patients with: (1) clinical evidence of sepsis; (2) fever (greater than 38.3 degrees C) or hypothermia (less than 35.6 degrees C); (3) tachycardia; (4) tachypnea; and (5) inadequate organ perfusion. Inadequate perfusion was defined as hypotension or evidence of peripheral hypoperfusion (poor capillary refill or cyanosis with hypoxemia, oliguria, acidosis or altered mentation). Inotropic support was required to maintain an adequate blood pressure and perfusion in 268 of 564 patients (47.5%). Septic shock with confirmed bacterial infection occurred in 143 patients (143 of 564, 25.2%); these cases were caused by Haemophilus influenzae, type b (59 of 143, 41.3%), Neisseria meningitidis (26 of 143, 18.2%) and Streptococcus pneumoniae (16 of 143, 11.2%). Eight of 564 (1.4%) cases of septic shock were not clinically apparent on initial evaluation and were diagnosed within 24 hours after admission to the hospital. We conclude that septic shock occurs more frequently in children than previously appreciated and may develop after admission to the hospital.

Dobutamine administration has been shown to increase oxygen delivery in various conditions, but there are little data to document its effects in septic shock. We investigated the effects of dobutamine infusion at a rate of 5 micrograms/kg.min in 18 patients (mean 60 +/- 16 yr) with septic shock initially characterized by hypotension, oliguria, and hyperlactatemia in the presence of a documented source of sepsis. Early resuscitation had consisted of fluid administration and vasopressors when required. When added to this standard regimen, dobutamine had no significant effect on mean arterial pressure (MAP) (from 71 +/- 12 to 73 +/- 13 mm Hg), but markedly increased cardiac index (from 3.0 +/- 0.7 to 3.9 +/- 1.0 L/min.m2, p less than .001), stroke index (from 32 +/- 8 to 37 +/- 9 ml/m2, p less than .001) and oxygen transport (from 410 +/- 105 to 530 +/- 146 ml/min.m2, p less than .001). Oxygen consumption (VO2) increased concurrently (from 137 +/- 42 to 162 +/- 66 ml/min.m2, p less than .002). MAP increased (from 68 +/- 9 to 76 +/- 11 mm Hg) in 12 patients and decreased moderately (from 76 +/- 18 to 69 +/- 17 mm Hg) in six patients. The two subgroups of patients had similar hemodynamic profiles before the dobutamine infusion, but vasopressor therapy was already used in one of the 12 patients in the first subgroup and in three of the six patients in the second subgroup (p less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)

The retrospective study of acute renal failure (ARF) in patients with hematologic neoplasms was carried out. ARF occurred in 32 (6.1%) of 526 patients with hematologic neoplasms. Twenty-one (66%) patients recovered from ARF, but only 7 (22%) survived and were discharged from the hospital and 25 (78%) died of ARF or other complications. In 17 patients with leukemia or malignant histiocytosis, sepsis and/or disseminated intravascular coagulation were the most common causes of ARF, and all 17 patients died. In 11 patients with multiple myeloma, ARF was always attributable to the underlying disease, and the clinical course improved with the initiation of blood purification therapy (hemodialysis, plasma exchange) and chemotherapy. Five patients in blast crisis of chronic myelogenous leukemia or non-Hodgkin's lymphoma developed ARF as a result of tumor lysis syndrome. In this group, renal function improved with hemodialysis but only 2 patients survived. Patients with oliguria had worse outcomes than those without oliguria. Survival appeared to depend not on renal function but on the underlying disease, the cause of ARF, and other complications. These findings suggest that, in patients with hematologic neoplasms complicated by ARF, early initiation of blood purification therapy will improve the prognosis.

We have recently experienced a case of Vibrio vulnificus septicemia which occurred in a patient with hepatic cirrhosis, and as we were able to give early antibiotic treatment, the patient survived. We would like to report this case here together with another case experienced 2 years ago. Case 1 was a 58-year-old male who was attending our hospital as an outpatient for hepatic cirrhosis. At 5:30 pm on August 8, 1987, he consumed abalone and giant clam and at 9 pm complained of high fever with shaking chills. He was admitted to our department as an emergency case. Cefoperazone was administered resulting in a decline of fever on the following day. During the course of treatment he fell transiently into pre-DIC, but due mainly to the administration of antibiotics his condition was subsided. Case 2 was a 53-year-old male who was under medical care in our hospital for grave hepatic cirrhosis. On October 11, 1985, he consumed sushi and two days later suffered chills and pyrexia. A blood culture revealed Vibrio vulnificus. His condition improved transiently with administration of Cefazolin, but oliguria, hypotension and ascites occurred subsequently, and finally the patient died on the 22nd day.

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 septic syndrome can be defined using clinical criteria in patients with clinical evidence of an infectious process. The other criteria include fever or hypothermia, tachypnea, tachycardia, and evidence of impaired organ perfusion or function as manifested by either altered mentation, hypoxemia, elevated plasma lactate, or oliguria. A multicenter trial using these criteria found positive blood cultures in 45 per cent of 382 patients. The mortality rate was approximately 30 per cent and 25 per cent of the patients developed ARDS. With respect to these characteristics, this septic syndrome population was very similar to the more traditionally defined populations with sepsis. Using the septic syndrome definition may allow for earlier detection of septic patients and possibly allow for earlier therapeutic intervention. The septic syndrome may help identify a population of patients at risk for the various complications of sepsis (that is, ARDS), aid in the search for pathophysiologic mechanisms, and allow for pharmacological trials earlier in the disease process.

The sepsis syndrome represents a systemic response to infection and is defined as hypothermia (temperature less than 96 degrees F) or hyperthermia (greater than 101 degrees F), tachycardia (greater than 90 beat/min), tachypnea (greater than 20 breath/min), clinical evidence of an infection site and with at least one end-organ demonstrating inadequate perfusion or dysfunction expressed as poor or altered cerebral function, hypoxemia (PaO2 less than 75 torr), elevated plasma lactate, or oliguria (urine output less than 30 ml/h or 0.5 ml/kg body weight.h without corrective therapy). One hundred ninety-one patients with the sepsis syndrome were evaluated prospectively and comprised the placebo group of a multicenter trial of methylprednisolone in sepsis syndrome and septic shock. Forty-five percent of the patients were found to be bacteremic. Thirty-six percent of the patients were in septic shock (sepsis syndrome plus a systolic BP less than 90 mm Hg or a decrease from baseline in systolic BP greater than 40 mm Hg) on study entry. An additional 23% of the patients developed shock after admission with 70% doing so within 24 h of study entry. Shock reversal occurred with a 73% frequency. Twenty-five percent of the patients developed the adult respiratory distress syndrome (ARDS). Mortality for the patients with sepsis syndrome who did not develop shock was 13%. Mortality for the groups of patients with shock on admission and shock postadmission was 27.5% and 43.2%, respectively. Forty-seven percent of the bacteremic patients developed shock after study admission compared to 29.6% of the nonbacteremic patients (p less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)

The first 100 liver transplantations at the Mayo Clinic were performed in 83 patients, who required a total of 917 patient days in the intensive-care unit (ICU). The mean duration of stay in the ICU was 5.91 days after liver transplantation and 6.15 days for patients who subsequently required readmission to the ICU. During the immediate postoperative period, hypothermia and hyperglycemia invariably occurred. Later during the initial admission or on readmission to the ICU, there arose the possibility of infections and renal insufficiency. Prompt diagnosis and treatment are necessary for hypertension, hypokalemia, severe metabolic alkalosis, fever, altered mental status, oliguria, and signs of graft failure in liver transplant patients. In our patient series, selective bowel decontamination minimized the occurrence of gram-negative and fungal sepsis, and use of antihypertensive agents and correction of coagulopathies may have decreased the risk of intracranial bleeding in patients with hypertension and clotting defects. Anticipation of potential conditions postoperatively and early implementation of treatment are key factors in the successful ICU management of patients who have undergone liver transplantation.
