Intra-aortic balloon pump in coronary artery bypass graft - factors affecting outcome

The management of coronary artery bypass graft (CABG) patients, especially in high risk patients ,can be challenging as the postoperative periods may be characterized by a low cardiac output state. Inotropes used in the perioperative periods to increase cardiac output may be detrimental thus making the use of mechanical devices like intra-aortic Balloon pump (IABP) for circulatory assistance desirable. To study the use of intra-aortic balloon pump in coronary artery bypass patients in preoperative and post operative settings and factors that affect morbidity and mortality. Madras Medical Mission, Chennai, India. A retrospective study of 3974 consecutive patients who had CABG done between March 2007 and February 2011 with or without additional procedures. One hundred and seven (2.7%) patients had IABP instituted either pre-operatively or postoperatively when it was obvious the patient will need cardiac assistance. The demographic data, clinical features, the indications for insertion, management offered and outcome , the creatinine levels, the duration of intraarortic balloon pump, the intensive care unit(ICU) and Hospital stay were analyzed for means and standard deviations and Pearsons Chi-square test using SPSS 10.0 window soft ware version with significant value of p-value
