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.

A prospective analysis of 155 patients with pulmonary embolism was undertaken to describe the radiographic characteristics of associated pleural effusions and related abnormalities. Approximately one half of these patients had pleural effusions. Patients with other potential causes of effusion, such as heart failure, pneumonia, or cancer, were eliminated from further analysis. In the remaining 62 patients, radiographic evidence of pulmonary infarction accompanied pleural effusions in one half of the cases. One third of patients with parenchymal consolidation had no evidence of effusion. Atelectasis and other nonspecific radiographic abnormalities occurred in less than one fifth of the cases. Typically, pleural effusions were small and unilateral, appeared soon after symptoms of thromboembolism began, and tended to reach their maximal size very early in the course of the disorder. Pulmonary infarction was associated with larger effusions that cleared more slowly and were more often bloody in appearance on thoracentesis. Chest pain occurred in all but one patient and was a valuable diagnostic clue. Pain and pleural effusions were always ipsilateral and almost always unilateral, but neither correlated well with the presence or time course of infarction. Effusions that were delayed in onset or that enlarged late in the course were associated with recurrent pulmonary embolism or superinfection. These radiographic features may be helpful in the diagnosis and management of pulmonary embolism.

Following episodes of pulmonary embolism, the presence of thrombi in the pulmonary arteries leads to severe respiratory insufficiency and chronic right heart failure. We have operated upon 16 such patients, nine men and seven women from 23 to 68 years of age. All had severe dyspnea, 14 had chronic cor pulmonale, six had mental disturbances with syncope, and four had severe cardiac failure. The presence of clots was demonstrated by pulmonary angiography, and the permeability of the distal arterial bed was ascertained by selective injection of the bronchial arteries. In all cases but two a lateral thoracotomy was used so that the obstructed arterial branches could be approached distally. The inferior vena cava was always ligated to prevent recurrences. There were six operative deaths, three from cardiac failure, one from acute pulmonary edema, one from hemothorax, and one following a pyothorax. Ten patients are surviving after 6 months to 10 years. One is still limited because of significant pleuropulmonary sequelae. Six are enjoying good results with marked improvement in their functional limitations, a significant drop in the pulmonary artery pressure, and radiological permeability of previously obstructed arteries. Three are excellent condition--completely asymptomatic.

The effect of intermediate coronary care, with and without ECG monitoring, was compared with general medical ward care on the basis of mortality, resuscitation, and detection and treatment of arrhythmias from days 3 to 14 after admission in 2,095 cases of acute coronary heart disease. Mortality was significantly reduced (P less than .02), and number of successful resuscitations for ventricular fibrillation was increased (P less than .05) but only in the unit with monitoring. Number of arrhythmias detected was significantly increased, particularly incidence of ventricular ectopics and heart block (P less than .02). Number of arrhythmias corrected to sinus rhythm was increased, but not significantly. Death from pulmonary embolism fell (P less than .01). Review of causes of death and autopsies showed an increased proportion of deaths due to intractable heart failure and cardiogenic shock. Not only specially trained nurses, but also ECG monitoring, were necessary to obtain the benefits of this treatment.

Analysis of the clinical and autopsy reports of 200 deaths following surgery for colorectal cancer from 1956 to 1974, at the Dept. of Surgery, University of Heidelberg, revealed that pneumonia (24.5%) was the most common cause of death followed by peritonitis (22%), pulmonary embolism (15.5%), advanced tumor disease (14%), cardiac failure (9.5%), ileus (5.5%), and others (9%). The explanation for the postoperative mortality rate of 12% (cancer of colon) and 13.2% (cancer of rectum) lies in the fact that 82.5% of those who died postoperatively were beyond the age of 60, and 40.5% beyond 70 years at the time of surgery. Moreover, in 50.5% advanced tumors with regional and/or distant metastases were found. In 55.5% severe preoperative complications (ileus: 38%, peritonitis: 11%, abscess formation or hemorrhage: 6.5%) required an emergency operation. Only 38.5% of the procedures were considered for cure. Besides the need for early recognition of the cancer, intensification of pre- and postoper treatment appears to be the predominant task in the effort to decrease postoperative mortality.

In the last 3 years 93 cases of iliofermoral trombosis were treated by surgery. We prefer the method used by Brunner, but under general anaesthesia and using a Bentley-Autotransfusion-System (ATS). The average age of our patients was 55 years (age ranged between 17 and 87 years). No lethal pulmonary embolism was observed. 2, 1 percent of the patients died following apoplex or acute heart failure. Of 67 patients who were operated on 6 months ago or more 70 percent have no further complaints, 28 percent still have some residual edema and only 2 patients have a severe postthrombotic syndrome. 50 percent of 40 control-phlebograms demonstrated patency of all veins. 20 percent had short segmentary occlusions with definite signs of recanalisation, while in 27 percent of the cases occlusions of the lower leg and thigh were found, the iliac veins being free. Only 2 postoperative phlebograms showed a complete iliofemoral venous occlusion. Our results prove, that the operative thrombectomy is a successful method, with which the main complications of the iliofemoral thrombosis-pulmonary embolisation and postthrombotic syndrome-can difinitely be reduced. Also because of better long term results, the operative therapy of acute ilofemoral thrombosis should be generally prefered instead of conservative treatment.

Causes of death of 260 tumorous patients autopsied in 1974 were analyzed. Most common causes were inflammation and tumorous and non-tumorous organ insufficiencies; the others, in order of decreasing incidence, massive tumorous dissemination, infarct and haemorrhage. Pneumonia was predominating over the inflammatory causes although peritonitis and sepsis were also not rarely encountered. Death due to inflammation occurred most frequently in cases of myeloid-lymphoid, urogenital and gastro-intestinal tumours and in postoperative states. The incidence of insufficiencies due to tumorous or non-tumorous origin differed but slightly. Of the various organ insufficiencies, massive hepatic metastases, occlusion of the biliary duct and cardiac failure were the most common. In cases of tumors of the small pelvis, compression of the ureters led most often to death. Massive dissemination was observed most of all in breast and ovarian carcinomas. Myeloid-lymphoid tumors led to death through extensive organ infiltration in about one thirds of the cases. After hearth infarction, venous thrombosis was often followed by pulmonary embolism, however, coronary occlusion was also not rare. Death due to haemorrhage originated from acute or chronic ulcers of the gastrointestinal tract or from vascular invasion of tumors in the head and neck regions or from thrombocytopaenia induced by cytostatics.

Sixteen cases of chronic Q fever are described. In eight there was a history of exposure to infection from farms or farm products. All had valvular heart disease, involving the mitral valve in nine and the aortic valve in seven. Infection occurred on a prosthetic valve in two patients. Arterial embolism was common. Venous thrombosis occured in three patients, and pulmonary embolism occurred in three other patients. Complement fixing antibodies to phase 1 antigen were found in a titre of 1:200 or greater in all except two patients. In one of these post-mortem examination revealed rickettsial bodies in mitral valve vegetations, and in the other Coxiella burneti was isolated from heart valve tissue. The majority presented with infective endocarditis but two presented primarily with liver disease. All patients had evidence of liver involvement and in one this led to death from cirrhosis. Abnormal tests of liver function, particularly hyperglobulinaemia, raised alkaline phsophatase and abnormal bromsulphthalein retention were found in all patients. Hepatic histology was abnormal in all eight patients in whom it was studied. The commonest features were mononuclear cell infiltration of the portal tracts and prominence of the sinusoidal Kupffer cells. Patchy focal necrosis of parenchymal cells, granulomata, fatty change, and eosinophilia of the sinusoidal walls were also noted in several patients and cirrhosis developed in one. Six patients had a purpuric rash, and in 12 there was thrombocytopenia. It is suggested that the presence of hepatomegaly and liver involvement and thrombocytopenia may help to differentiate Q fever endocarditis from bacterial endocarditis. Raised serum IgM and IgA levels occured frequently, but with only a moderate dominance of IgM. Sheep cell agglutination and latex fixation tests for rheumatoid factor were occasionally positive. Several features of the disease suggest the possibility that immune-complex mechanisms may play a role in chronic Q fever. Treatment was with prolonged courses of tetracycline usually combined with lincomycin. Seven patients underwent valve replacement surgery for haemodynamic reasons. Five patients died; two from heart failure, one from cirrhosis, one seven days after valve replacement and one from intraperitoneal haemorrhage following percutaneous liver biopsy. Three patients have survived for more than five years, and another six for more than three and a half years after diagnosis. Of these nine patients, three received medical therapy alone and six required valve replacement as well. Antibiotics have been discontinued in four patients who have had valve surgery and three others. Six patients had received antibiotics for continuous periods varying from 29-62 months. In the period after stopping therapy varying from 15-21 months, no relapse has occured. A seventh patient, who had received antibiotics for four months prior to valve replacement, has survived 43 months after the withdrawal of antibiotics...

It was established by means of radioimmunoassay that the blood concentration of Digoxin in patients with congestive heart failure depends not only on the dose of the drug given, but also on the stage of cardiac insufficiency. With equal daily doses, higher Digoxin concentrations were observed in patients with more severe cardiac insufficiency. The analysis of the obtained data has demonstrated that in 75% of the patients with signs of digitalis intoxication the concentration of Digoxin in blood exceeded 2.5 ng/ml. In animal experiments it was established that a distinct reduction of the toxic threshold took place in rabbits with acute myocardial infarction, acute pulmonary embolism, congestive cardiac failure, this threshold being determined by the amount of intravenously injected Strophantin that causes persistent ventricular tachycardia.

Pulmonary embolectomy under cardio-pulmonary bypass was performed in five patients with massive embolism. Two survived and were ultimately discharged; two died after 40 and 101 days, respectively, of the underlying disease; one patient--operated on under a mistaken diagnosis--was maintained under assisted circulation but died after four days of the underlying disease (cardiac failure). Indications for pulmonary embolectomy under cardiopulmonary bypass should be widened, as it is the only life-saving measure in most cases. After moderately severe pulmonary embolism (lobar embolism) indications for surgical intervention must be individualised from case to case.
