ObjectiveTo evaluate the efficacy of incisional ropivacaine infiltration by presternal multi-orifice catheter to manage poststernotomy pain in pediatric cardiac surgery.DesignA prospective, randomized, and double-blind comparative study.SettingAt a single-institution tertiary referral cardiac center.ParticipantsThe study comprised 200 children undergoing cardiac surgeries through a midline sternotomy.InterventionsChildren were allocated randomly to 1 of 3 groups. Group A (n = 65) and group B (n = 64) received 0.375% ropivacaine infusion and intermittent bolus, respectively, by presternal multi-orifice catheter, whereas Group C (n = 64) did not receive any local anesthetic (LA) drug. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl was given as rescue analgesia, respectively.Measurements And Main ResultsPain was assessed by a Modified Objective Pain Score (MOPS) for 48 hours postextubation. Group B had significantly lower early MOPS at the first hour, but in the later period, the mean MOPS was lower in group A. The requirement of the first rescue analgesia was 3 ± 1.51, 6.1 ± 2.26, and 2.6 ± 0.87 hours for groups A (n = 60), B (n = 60), and C (n = 60), respectively. The 48-hour fentanyl consumption was significantly lower (p < 0.001) in group A (0.5 ± 0.68 µg/kg) and group B (0.7 ± 0.86 µg/kg) than the control group (3.4 ± 0.68 µg/kg). The length of intensive care unit stay was lower (p < 0.001) in groups A and B than in group C; however, the length of hospital stay was comparable (p = 0.07).ConclusionLA bolus and infusion through presternal multi-orifice catheter provided effective analgesia postoperatively. However, the bolus was more efficacious in the early phase but equivalent in later periods. Therefore, bolus and LA infusion can be used for steady poststernotomy pain relief in children undergoing cardiac surgeries.Copyright © 2023 Elsevier Inc. All rights reserved.
