Caudal anesthesia in pediatric cardiac surgery: does it affect outcome?

摘要

OBJECTIVE: The purpose of this study was to examine the influence of caudal anesthesia on outcomes (pediatric intensive care unit [PICU] length of stay, hospital length of stay, ventilatory time, early extubation rate) in pediatric patients undergoing congenital heart disease repair requiring cardiopulmonary bypass (CPB). DESIGN: Retrospective. SETTING: University teaching hospital. PARTICIPANTS: Pediatric patients undergoing surgery to treat congenital heart disease between 1999 and 2002. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Thirty-four patients with atrial septal defect (ASD), 37 with ventricular septal defect, and 46 with tetralogy of Fallot (TOF) were included in the analysis. No differences were found in preoperative and intraoperative data between caudal and noncaudal group for each disorder. There was no difference between caudal and noncaudal groups in PICU and hospital stay. A statistically significant difference was found in the postoperative ventilatory time in patients with ASD and TOF between caudal and noncaudal groups. The early extubation rate was higher in the TOF caudal group compared with the noncaudal group. CONCLUSIONS: This retrospective study demonstrated that postinduction placement of caudal anesthesia does not affect PICU or hospital length of stay. A well-controlled prospective study is needed to confirm these findings.
