Context: Regional anesthesia may attenuate adverse physiological stress responses associated with cardiothoracic surgery. In this study, hemodynamic stress response at the different time of surgical stimuli was compared between patients receiving general anesthesia (GA) along with caudal epidural analgesia with GA with intravenous analgesia in pediatric population undergoing open-heart surgery. Aims: This study aims to compare the hemodynamic response at the different time of surgical stimuli and postoperative pain score, in pediatric patients undergoing open-heart procedures. Settings and Design: We designed a prospective randomized controlled trial to study hemodynamic effects between Group I and Group II. Fifty patients were randomly allocated equally into Group I (GA + caudal epidural) and Group II (GA + intravenous analgesia) by sealed envelope technique. Subjects and Methods: After obtaining approval from Institutional Ethical Committee, this prospective study was conducted in 50 American Society of Anesthesiologist Classes II and III pediatric patients aged between 1 and 12 years posted for cardiac surgery in our institution. Statistical Analysis: ANOVA, two-way ANOVA, and Student's test. Results: The heart rate, systolic blood pressure, diastolic blood pressure and mean blood pressure variations were compared between Groups I and II at different time intervals. The variations were found to be significantly higher at the time of skin incision and 2 min after skin incision in Group II as compared to Group I. Pain score was compared between the groups and was found to be significantly lower with Group I (2.5 ± 1.2) as compared to Group II (4.6 ± 1.7), P = (0.004). Conclusions: Caudal analgesia with GA (Group I) was found to have better hemodynamic control and significantly better postoperative pain relief in the first 24 h after awakening.
