title: Prophylactic use of intra-aortic balloon pumps in open heart surgery.
abstract: During a 1-year period, intra-aortic balloon pumps (IABPs) were used in open heart surgery on 57 patients. Indications were prophylactic usage for coronary artery bypass grafting (CABG) in 52 patients, prophylactic usage for valve replacement in three patients, and cardiopulmonary bypass (CPB) weaning during valve replacement in two patients. The 52 CABG patients comprised 94.5% of all CABG procedures during the period. Sheathless 8 Fr IABPs were used in all cases. The 57 patients using IABPs were analyzed. The mean duration of IABP use was 41.7 h. Morbidity was not associated with using IABPs. There was one case of balloon rupture. Hemostasis was performed easily after removing IABP catheters by compressing the groin for approximately 15 min. The lowest blood pressure during anastomosis or cardiac arrest was also assessed. The lowest peak pressure was 55.9 ± 17.3 mm Hg for patients with IABP still turned on, and the lowest mean pressure was 34.7 ± 6.5 mm Hg for patients with IABP temporarily turned off. Peak blood pressure after CPB was 73.8 ± 17.8 mm Hg. During open heart surgery under anesthesia with the low blood pressure presented by this series, use of IABPs enabled patients to tolerate the procedure. In conclusion, aggressive use of IABPs is easy, safe, and effective with no related morbidity.
