Surgical complications of extracorporeal circulation

Complicaciones quirúrgicas de la circulación extracorpórea

Introduction: extracorporeal circulation in cardiovascular surgery replaces cardiac and pulmonary function, which generates functional and systemic changes that expose the patient to complications. Objective: to determine the intra and postoperative in operated by cardiovascular surgery with extracorporeal circulation. Methods: descriptive cross-sectional study. We analyzed 139 clinical records of adults from January 2009 to June 2011. The variables analyzed were demographic, comorbidities, procedures performed, pump times and occlusion of the arterial line, myocardial protection used and hospital stay. The complications were analyzed with the statistical program stata. Results: the systems with greater complications were cardiac 79%, circulatory 50% and pulmonary 48%. The average age was 61 years, 64% were women. The most frequent antecedents were 81% arterial hypertension, 36% smoking and 35% dyslipidemia. There was evidence of 14% of intra-surgical complications and 86% postoperative complications. Conclusions: the use of extracorporeal circulation leads to greater postoperative complications. Those who presented arterial hypertension, smoking and dyslipidemia were more predisposed to cardiac, circulatory and pulmonary complications, as well as those who had prolonged occlusion of the arterial and pump lines.
