A total of 4056 consecutive patients operated for benign biliary tract disease between January 1983 and June 1990 were reviewed retrospectively. There were 71 in-hospital deaths, representing 1.75% of morality rate. Cholecystectomy was performed in 2275 patients; common bile duct exploration was carried out in 1494, with operative mortality rates of 0.4% and 3.1% respectively. Sepsis was the leading cause of mortality. The second common cause of death was hepatic failure, and respiratory failure the third. Cardiovascular problems accounted for 11.3% of death, which was much lower than reports from western series. Other causes of mortality included hypovolemic shock, anaphylactic shock, epilepsy and hypoglycemia. Of the total 4056 patients, 28.5% underwent emergency surgery. The mortality rate for emergency surgery was 3.6 times higher than for those who underwent elective operations (p less than 0.005) Significantly higher mortality rates were also seen for those aged over 70 years and of male gender. Because the mortality rate of patients who underwent emergency operation due to acute inflammatory or obstructive complications were much higher than that of elective operation group, we suggested early surgical intervention for the symptomatic patients before complications occurred.

Respiratory complications are important causes of mortality in severe acute pancreatitis. We analyzed the pleuropulmonary complications that occurred in a series f 63 patients with severe acute pancreatitis. The most frequent were respiratory failure (52.4%) and bronchopulmonary infection (33.3%), both associated with sepsis and a high mortality rate. The initial laboratory workup included serial arterial blood gases and chest roentgenogram within the first 24 hours. The latter was useful to predict mortality. The tracheobronchial cultures isolated only enteral bacteriae. We conclude that pleuropulmonary complications are clearly related to the outcome of severe acute pancreatitis, specially when associated to sepsis.

Acute respiratory failure in pregnancy is an important cause of maternal and fetal morbidity and mortality. Causes include: ARDS, venous air embolism, beta-adrenergic tocolytic therapy, asthma, thromboembolic disease, pneumothorax, and pneumomediastinum. The most common predisposing diseases for ARDS complicating pregnancy are sepsis, pneumonia, aspiration of gastric contents, and amniotic fluid embolism. Knowledge of normal maternal-fetal physiology and determinants of fetal oxygen delivery (uterine blood flow, placental transfer, fetal circulation) can help sustain normal fetal development, usually without compromising maternal care. The increased microvascular permeability seen in ARDS is likely mediated by neutrophils, proinflammatory mediators (e.g., tumor necrosis factor, interleukin-1, arachidonic acid metabolites) and activation of the complement cascade. Treatment of respiratory failure in pregnancy is largely supportive, including mechanical ventilation, hemodynamic support, nutrition, and prophylaxis against thromboembolism. No specific therapy has as yet been proven effective for ARDS, other than treating the underlying cause. Respiratory failure from status asthmaticus is treated with vigorous bronchodilator therapy, high-dose glucocorticosteroids, magnesium sulfate, and careful ventilator management. Occasionally, more experimental therapies (e.g., isoproterenol infusion, halothane anesthesia) are indicated. Certain strategies can help prevent respiratory failure from aspiration of gastric contents, beta-adrenergic tocolytic therapy, and thromboembolic disease.

Extracorporeal membrane oxygenation (ECMO) is effective for newborns with pulmonary failure unresponsive to conventional therapy. However, ECMO for the older child and adult has been controversial and not widely utilized. Over 4 years, 24 patients (aged 4 months to 16 years; 11 boys, 13 girls) underwent venoarterial ECMO (duration, 7 to 19 days) for respiratory failure. The diagnoses were: viral pneumonia (7), hydrocarbon aspiration (6), sepsis with adult respiratory distress syndrome (ARDS) (2), bacterial pneumonitis (2), tracheal stenosis (1), bilateral pulmonary contusion (1), diaphragmatic hernia with ARDS (1), ketoacidosis with ARDS (1), pulmonary artery injection of hydrocarbon (1), drowning (1), and epiglottis with barotrauma (1). Pre-ECMO blood gas ranges (and means) were PO2 18 to 65 (46), and PCO2 47 to 112 (65). Nineteen patients received dopamine, dobutamine, or other inotrope for associated cardiac and/or renal failure. Cannulation for ECMO was through neck or groin vessels in 17, and sternotomy in 7. ECMO flow rates were 150 to 250 mL/kg/min, to maintain PO2 greater than 100 and PCO2 less than 40. Nine patients (41%) survived ECMO, with eight long-term survivors, (4 hydrocarbon aspiration or injection, 1 pulmonary contusion, 1 viral pneumonia, 1 ARDS, 1 barotrauma), three of whom have mild neurological deficit. All patients with sternotomy, and 8 of 15 with neck and/or groin cannulation, required 1 to 5 explorations for hemorrhage while on ECMO. All survivors had primarily pulmonary failure; patients with combinations of pulmonary, cardiac, and renal failure did not survive. ECMO can be life-saving in the child with isolated pulmonary failure, but its efficacy in patients with multiorgan failure is uncertain.

Pancreatic complications following cardiopulmonary bypass are infrequent but are associated with high mortality. All cases of pancreatic complications following cardiopulmonary bypass from 1972 to 1987 at a single institution were retrospectively reviewed. Of 5621 patients who underwent cardiopulmonary bypass, 25 (0.44%) sustained pancreatic complications. There were 15 cases of acute pancreatitis and 10 cases of pancreatic necrosis, with 11 deaths in the group reviewed, a mortality rate of 44%. Factors that were correlated with mortality associated with pancreatic complications in this study include preoperative hypotension, preoperative use of inotropic agents, and renal failure (preoperative and postoperative). Factors that have been previously associated with mortality from pancreatic complications in other studies, such as fluid sequestration, respiratory failure, sepsis, tachycardia, hypocalcemia, age greater than 55 years, and abnormal laboratory findings, were not found to be significantly associated with mortality in this study. Of the five patients for whom complete data were available, not one patient received greater than 800 mg of calcium per square meter of body surface area in the perioperative period. While the exact mechanism of pancreatic injury remains unclear, based on experimental studies and clinical correlation, it is likely that pancreatic ischemia remains a significant contributing factor. We conclude that no factor specifically associated with cardiopulmonary bypass was correlated significantly with mortality.

The clinical features of 22 postoperative multiple organ failure (MOF) patients, comprised of 8 with arterial disease (A-MOF) and 14 with gastrointestinal cancer (G-MOF), were investigated. Differences in the operative time, blood loss, and mortality were not significant. The initial organ impaired was the lungs in 78.6% of G-MOF patients and the heart or kidneys in all A-MOF patients. Infection developed in over 80% of both groups. In many A-MOF patients, the pneumonia or septicemia developed secondary to organ failure, while intraabdominal infection triggered respiratory failure in many G-MOF patients. Our organisms in infected specimens and their antibiotic sensitivities was valuable for the early administration of effective antibiotics. Upper gastrointestinal tract bleeding was important in the prognosis of both groups and occurred more frequently in A-MOF than in G-MOF patients. Consumption coagulopathy in A-MOF patients and DIC induced by infection in G-MOF patients mainly caused such bleeding. Preoperative administration of heparin was effective in improving coagulopathy. Furthermore, measurement of intramural pH with tonometer in the stomach and gastric irrigation with oxygenated perfluorochemicals were effective in the prediction and prevention of gastrointestinal bleeding.

The acute respiratory distress syndrome (ARDS) is a late complication in critically ill patients and its diagnosis is usually made when the syndrome is fully established. There is an increased interest in developing early markers that may help to identify ARDS in its initial stages. Calcitonin was recently reported as a useful serum marker to identify burned patients at risk for respiratory failure. We report a case with abdominal sepsis and ARDS, whose serum calcitonin level was 1000 pg/mL without other known clinical causes of hypercalcitoninemia and who died in multiorganic failure. The possible mechanisms of hypercalcitoninemia and its possible utility as marker of ARDS in critically ill patients is discussed.

In order to evaluate the changes in causes and outcome of acute renal failure (ARF) during the years 1975-1989, 710 patients treated in our dialysis center were analyzed. We compared the etiology, the severity and catabolic state of ARF, the techniques of renal replacement therapy, which were employed and the ages and mortality rates of these patients, who received dialysis therapy during the years 1975-79 (n = 227), 1980-84 (n = 240) and 1985-89 (n = 243). The number of postoperative, posttraumatic and non-traumatic cases of ARF was approximately the same in all three 5-year periods, only the frequency of postrenal failure decreased from 7% in the years 1975-79 to 3% in the years 1985-89. The incidence of sepsis as a major cause of ARF and the most important risk factor was comparably high in the surgical and medical patients during all of the periods, but it increased in the traumatic patients from 7% in the years 1975-79 to 28% during the last 5-year period. The prevalence of respiratory failure and jaundice as additional organ failures, the severity of ARF (oligonanuric-nonoliguric) and the metabolic state were not different in the three patient groups. The magnitude of rise in serum creatinine before the start of renal replacement therapy was significant lower in the last 5-year period in comparison to the years 1975-79 (p < 0.05). Hemodialysis was the treatment in choice of 98 and 93% of the cases during the first two periods, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Very recently, the concept of artificial intracorporeal oxygenation of blood for patients suffering from respiratory failure has been introduced into clinical practice through development of a totally implantable intravascular oxygenator (IVOX). We report on the use of such a device in a patient who developed severe respiratory insufficiency secondary to prolonged hypovolaemic shock and pneumonia following successful repair of a ruptured abdominal aortic aneurysm in September, 1990. Postoperatively, severe hypoxaemia occurred (AaDO2 548-602 torr) despite extensive mechanical ventilatory support. There was no obvious chance to overcome this situation by conventional therapeutic measures and the decision was made to institute IVOX therapy. Hypoxaemia was resolved immediately and both FiO2 and tidal volume could be reduced within hours. The patient's respiratory condition continued to improve over the next days leading to termination of IVOX therapy after 71 hours. However, the necessity of long-term ventilatory support secondary to recurrent pneumonia and sepsis, multiple abdominal reoperations for ischemic colitis and retroperitoneal abscess prolonged his recovery. He was discharged from the hospital after four months and is alive and well now 14 months after his operation. He is the first long-term survivor after IVOX therapy in Europe. IVOX may be successfully used in selected patients while the indications and it's potential role in the therapy of severe respiratory failure still need to be defined.

Five years of experience gained with the CryoCare Extremity Stabilization System (CESS) were evaluated in this study. Twenty-one patients underwent freezing amputation. Five patients died before undergoing surgical amputation. Symptomatic relief, control of odor, decreased demand on nursing staff, and appreciation of the family make this approach valuable even when long-term survival is not anticipated. Ten patients who underwent freezing amputation subsequently underwent surgical amputation and were discharged. Six patients underwent freezing and surgical amputation but died prior to discharge. The patients selected for the freezer application were deemed to be prohibitive operative risks because they were experiencing systemic toxicity from their ischemic limb and underlying diseases. Six patients demonstrated myoglobinuria prior to freezing which cleared with CESS. The physiologic amputation allowed stabilization of medical problems including cardiac arrhythmias, congestive heart failure, sepsis, renal failure, diabetes, and respiratory failure. Freezing of an ischemic extremity allows delay in amputation enabling physicians to achieve maximal medical stabilization. It permits symptomatic relief in patients whose long-term survival is not anticipated. Physiologic freezing amputation should be included in the repertoire of all surgeons.
