Abstract
Introduction: Our primary aim was to examine postoperative complications in cardiac surgery patients and their relationship to the use of cardiopulmonary resuscitation (CPB). A secondary aim was to evaluate the association of postoperative complications with outcome measures. Material and Methods: Single-institution observational study of consecutive cardiac surgery patients over 1 year. Five cardiac cases and 15 extracardiac cases were studied. CPB use, CPB parameters, demographics and Risk Adjusted Classification of Congenital Cardiac Surgery (RACHS-1) levels were evaluated as complication risk factors. Outcomes examined included duration of mechanical ventilation, length of stay in pediatric hospital, length of stay, and mortality. Results: Logistic regression analysis, after adjusting for age, sex, prior sternotomy, and RACHS-1 level, provided insufficient evidence for an association between CPB support and the incidence of cardiovascular or extracardiac problems. For patients receiving CPB, longer duration of CPB, higher RACHS-1 levels, and lower CPB temperature were associated with more cardiovascular events (P < .01). Longer CPB duration and higher RACHS-1 levels were associated with more cardiovascular complications (P = .006). Postoperative complications were associated with longer ventilator time, longer pediatric heart failure hospital stay, longer hospital stay, and death (P < .01). Conclusion: Postoperative complications occurred in 43% of pediatric cardiac procedures with and without CPB. Complications include longer use of ventilators, pediatric heart failure and hospital stay, and increased mortality.
