title: Post-cardiotomy intra-aortic balloon counter pulsation: application and prognostic evaluation.
abstract: Cardiac assistance by intra-aortic balloon counter pulsation was studied in 113 cardiac surgical cases comprising 91 male and 22 female patients. This included 82 percent of patients having coronary artery bypass surgery, while 18 percent were operated for valvular lesions. It was observed that the time of institution of cardiac assistance by intra-aortic balloon counter pulsation, following cardiac surgery, was of prime importance to decrease patient mortality. It was lowest (16%) when the balloon was inserted for assistance before termination and highest (50%) when there was delay of more than 15 minutes following termination of cardiopulmonary bypass. Early balloon assistance significantly lowered the pulmonary capillary wedge pressure and usually 1:2 augmentation was more effective, probably because of existing tachycardia in most patients. Advances in catheter technology have reduced the vascular complication at the insertion site. Percutaneous insertion had less local complications (13.3%) than open arteriotomy technique (31.2%). Similarly with sheathless insertion, complications were less (6.6%) in comparison to sheathed insertion (21.7%). Proper placement of balloon avoided position-related complications and there was no compromise of blood flow through left internal mammary artery as noticed in our series.
