Abstract

The cardio pulmonary bypass (CPB) is used in heart surgery for circulatory and respiratory replacement. The effectiveness of this technique, as well circulatory as respiratory goes and will go to spread its use far beyond the strictly surgical field. The unexpected starts on CPB include not provided starts, anticipated stars, and renewed stars. The not provided starts concern going on CPB for a cardiac or respiratory failure, not reacting to the conventional techniques of cardiopulmonary resuscitation and rare cases of inability to access the airway in emergency. This could be an exceptional complement to external cardiac massage. The anticipated departures involve patients in the operating room for cardiac surgery for which the establishment of the CPB has to treat with emergency life threatening brutal cardiac failure on valvular or coronary artery disease. The renewed starts are being on CPB or after weaning of CPB. It is being CPB to change a failed oxygenator responsible for a tissue hypoxia or replace a piece of tube main circuit of the CPB. A new start on CPB after weaning is essentially for circulatory assistance made necessary by postcardiotomy heart failure, by side effects of protamine injection, excessive bleeding or intra cardiac thrombosis. The oxygenator replacement techniques in emergency are exposed. This techniques demand a well trained and mobile medical and para medical staff.
