Complications are the major causes of illness and death after burning and most of them stem from the burn wound. Their origin and importance are reviewed with emphasis on problems and growing points in knowledge. Fluid leakage from the circulation into the burn is the cause of hypovolemic shock, but the underlying permeability changes in the burn are only partly understood. Other nonbacterial complications include acute cardiac failure, acute anemia, hemolytic jaundice, renal failure, encephalopathy, complex hypermetabolic effects including pseudodiabetes, gastric and duodenal ulceration, deep vein thrombosis and pulmonary embolism, pulmonary and glomerular microthrombosis, hepatic jaundice, and arterial thrombosis. Involvement of the airway in conflagrations carries special hazards like glottic edema and inhalation of irritant fumes. Nowadays, bacterial causes are dominant and these remain the main challenge. Bacterial infection and invasion of the burn are usually responsible for septicemia, bronchopneumonia, and pyelonephritis although other sources also contribute. Indirect manifestations of septicemia include paralytic ileus, acute gastric dilatation, toxic myocarditis, and some cases of renal failure. Therapeutic complications like agranulocytosis, thrombocytopenia, and colitis occur at times. High concentrations of oxygen given therapeutically can produce fatal aseptic hypoxic pneumonitis.

An 86-year-old man with previous normal renal function was hospitalized because of renal insufficiency. He had a long history of atherosclerotic heart disease, mild hypertension and pulmonary embolism, requiring anticoagulant therapy. In view of the normal-sized kidneys and absence of casts in the urinary sediment, a diagnosis of atheroembolic renal disease was made. The patient's renal function deteriorated, but he refused hemodialysis. Death occurred within a few weeks. At autopsy, severe aortic atherosclerosis was observed and atheroembolic renal disease was confirmed as the cause of renal failure. Occasionally, renal failure can be the sole manifestation of spontaneous atheroembolic disease. This possibility should be considered if the physician is called upon to establish the diagnosis when renal insufficiency develops in atherosclerotic patients.

Very significant morbidity and mortality continue to accompany lower extremity amputations. In this study 90 patients underwent 110 amputations over a 4 year period. The overall complication rate was 40 per cent and the overall mortality rate 12.2 per cent. The patients at greatest risk were the above knee amputees greater than 60 years of age with peripheral vascular disease. Amputation of the lower extremity must be recognized as a major, life-threatening procedure. Careful preoperative evaluation of cardiac, pulmonary, and nutritional status along with efforts to prevent sepsis, pneumonia, pulmonary embolism, gastrointestinal ulceration, and renal failure are necessary if the mortality accompanying these procedures is to be reduced.

Heparin disappearance after injection and plasma levels during continuous infusion were studied in normal subjects and patients with thrombophlebitis, pulmonary embolism, renal failure, and liver failure. Heparin removal in normal subjects after 75 u/kg was nearly linear with a clearance of 0.64 ml/min/kg, SD +/- 0.11. Clearance varied inversely with dose. Heparin clearance in pulmonary embolism (0.80 ml/min/kg +/- 0.23) was significantly accelerated compared both to normals (P less than 0.005) and to thrombophlebitis patients (0.55 ml/min/kg +/- 0.19, P less than 0.01); the disappearance was more curvilinear in thrombophlebitis and pulmonary embolism than in normal subjects (P less than 0.025). Continuous infusion heparin requirements were greater in pulmonary embolism than in thrombophlebitis, in accordance with pharmacokinetic predictions. The pattern and rate of disappearance in renal disease was similar to normal subjects; in liver disease clearance was accelerated (0.86 ml/min/kg +/- 0.28) and disappearance curvilinear. Because of accelerated clearance, the initial dose of heparin in pulmonary embolism should be greater (25 u/kg/h) than in thrombophlebitis (10-15 u/kg/h). Variability within patient groups necessitates some laboratory control of dosage.

Thrombosis of the inferior vena cava rarely occurs. However, it mostly develops by continous growth from thrombosis of the deep leg and pelvic veins. Thrombus formation in the inferior vena cava carries a potentially lethal risk because of possible involvement of the renal veins with consecutive renal failure or development of fulminant pulmonary embolism. Therapy of choice consists in early diagnosis and immediate thrombectomy. Choice of the operative procedure is of the utmost importance for immediate and late results. Our technique consists of inserting a balloon catheter via a side vessel of the internal jugular vein and placing it into an infrarenal position, where it is blocked, thereby preventing blood flow from the area to be cleared. Three cases in which this technique was employed are presented.

Fifty-seven patients with colonic injuries were treated by primary repair with or without exteriorization. Forty-six of these had other associated major intra-abdominal, intrathoracic, and musculoskeletal injuries. All had minimal contamination of the peritoneal cavity and were operated upon within 6 hours of injury. None showed any evidence of anastomical leakage or breakdown. Minor complications occurred in 12 patients (21%). Two deaths (3.5%) resulted, but neither was attributable to the repair of the colon; one died from renal failure and the other from pulmonary embolism. On the basis of this study, it is concluded that most isolated injuries of the colon resulting from low-velocity bullets and sharp objects can be closed primarily if peritoneal contamination is minimal and antibiotics are administered immediately after injury, during operation, and post-operatively.

An 85-year-old female diabetic was admitted in coma, having been on antidiabetic treatment with the biguanide derivative "Silubin retard", 600 mg/d, for one-and-a-half months. The anion deficiency was 57 mmol/l, pH 6.9, suggesting the diagnosis of lactic acidosis in the absence of other causes of metabolic acidosis. Blood lactic acid levels of more than 16.65 mmol/l (150 mg/100 ml) confirmed the diagnosis. Administration of 875 mmol sodium bicarbonate over 12 hours corrected the deficiency. On admission to hospital there had been slight pre-renal failure. Myocardial infarction developed as a result of tissue hypoxia but did not prove clinically important. On the second day there were signs of a compensated disseminated intravascular coagulopathy with upper gastro intestinal haemorrhage. The woman died suddenly 18 days later of pulmonary embolism.

Fifty-five patients of mean age 69 (range 41-96) years with rectal cancer (Dukes' A:B:C, 11:24:20) underwent anterior resection using a double stapling technique under the care of one consultant surgeon between 1983 and 1988. The mean distance of the anastomosis from the anal margin was 7.2 (range 4-13) cm. The clinical leak rate was 9 per cent (five patients). There were three postoperative deaths from pulmonary embolism, lower limb ischaemia and renal failure. On prospective follow-up, 35 patients had no evidence of local or systemic cancer a median of 32 (range 24-84) months after operation; seven have died from unrelated diseases and ten from metastatic cancer. Pelvic recurrence, in four patients at 9, 11, 12 and 50 months, has occurred only in association with widespread metastasis. These results suggest that the theoretical risks of an increase in the local recurrence rate of rectal cancer after resection using a double stapling technique are not substantiated.

Four years after an HIV infection and without any preceding illness characteristic of AIDS, a 24-year-old woman developed dyspnoea on exertion and peripheral oedema. She had for several years been an intravenous drug addict and contracted hepatitis A and B. There were no symptoms of the HIV infection. Clinical, radiological and echocardiographic examination demonstrated right ventricular failure caused by pulmonary hypertension not due to pulmonary embolism or another known aetiology. The patient died suddenly 9 months after the diagnosis from heart failure. Autopsy established primary pulmonary hypertension with pathognomonic plexogenic pulmonary arterial disease which had led to cor pulmonale with overload myocarditis. Although there had been no clinical signs of renal failure, there was histological evidence of mesangioproliferative glomerulonephritis and non-destructive interstitial nephritis. This case demonstrates that, in addition to the typical AIDS-associated diseases, other rarer syndromes may, in uncertain ways but connected with the HIV infection, decide the prognosis of such patients.

Spinal cord injury increases the risk of many life-threatening medical problems, including respiratory failure, pulmonary embolism, and renal failure. Respiratory failure results from paralysis of muscles of inspiration (which impairs oxygen transport to alveoli) and of expiration (which impairs cough and predisposes to pneumonia and atelectasis). Respiratory failure in patients with spinal cord injury can be prevented by proper positioning of the patient, training of ventilatory muscles, pulmonary toilet, and aggressive use of antibiotics and bronchodilators. When respiratory failure occurs, it can be managed by administration of oxygen, intubation, and mechanical ventilation, and in instances of paralysis of the diaphragm, by diaphragmatic pacing. The risk of deep vein thrombosis and pulmonary embolism in acute spinal cord disease is increased by the immobilization of the patient and abnormalities in clotting factors. Thrombotic disease in spinal cord disease can be prevented by intermittent calf compression and heparinization. If pulmonary embolism develops, the patient should be started on a regimen of warfarin for at least 3 months. If anticoagulation is contraindicated, a Greenfield filter can be placed. However, concurrent use of quad cough places the patient at increased risk for complications from the Greenfield filter. Chronic pyelonephritis and systemic amyloidosis are the most common causes of renal failure in the patient with spinal cord disease. Renal failure can be prevented by maintaining a low postvoid residual volume, avoidance of indwelling catheters, use of medications that are not nephrotoxic, and rapid treatment of infection. Hemodialysis and peritoneal dialysis can extend the life of the patient with spinal cord disease in whom renal failure develops, and successful use of renal transplantation has recently been reported.
