RESUMO
The perioperative management of 286 patients scheduled for open heart surgery has been described. Mortality associated with anaesthesia (0.4 percent), patient monitoring and measurement (0.4 percent) and cardio-pulmonary bypass (1.4 percent) has been low. Morbidity produced by these techniques has been reversed with supportive therapy. It is concluded that the techniques of anaesthesia, patient monitoring and measurement, and cardiopulmonary by-pass as reported herein are acceptable and safe for the patient undergoing open heart surgery. Operative mortality in the majority (114 patients) age group of 10-20 years has been relatively low (18 percent). However, cardiac failure is dominant as a major cause of early (operative) and late mortality. It is the authors' opinion that technical problems of intracardiac repair and cardio-pulmonary bypass in patients below 5 years, and errors in deciding operability have largely contributed to refractory cardiac failure. It is hoped that more critical selection of patients for operation and greater experience in operative techniques, would result in a decrease in operative deaths (AU)
