Does epidural analgesia really enhance recovery in pediatric surgery patients?

Purpose: We sought to determine the benefits of epidural anesthesia (EA) in pediatric surgical patients.

Methods: This study is a single-institution retrospective review of EA for pediatric patients undergoing thoracotomy or laparotomy from 2015 to 2020. Patients with recent or chronic opioid use were excluded. Urgent or emergent cases, patients with hemodynamic instability, or those with surgical complications that significantly impacted their post-operative course were also excluded. The primary objectives were comparison of pain scores and systemic opioid use between those patients with EA and those without EA.

Results: Epidural anesthesia was used in 151 (81.6%) laparotomies and 58 (77.3%) thoracotomies. EA use was associated with lower mean systemic opioid administration during the early post-operative period for laparotomy (POD#0-0.33 ± 0.3 oral morphine equivalents per kilogram (OME/Kg) with EA vs 0.93 ± 1.53, p < 0.001, POD#1-1.34 ± 1.79 OME/Kg with EA vs 2.61 ± 2.60, p < 0.001) and thoracotomy (POD#0-0.40 ± 0.37 OME/Kg with EA vs 0.68 ± 0.41, p = 0.008, POD#1-0.89 ± 0.86 OME/Kg with EA vs 2.02 ± 1.92, p < 0.001). There were no differences seen by POD#2. Average pain scores were significantly lower in patients with EA following laparotomy (POD#0-1.22 ± 0.99 with EA vs 1.75 ± 1.33, p = 0.008) and thoracotomy (POD#0-1.71 ± 1.13 with EA vs 2.40 ± 1.52, p = 0.04).

Conclusions: The use of EA in pediatric surgery patients was associated with lower pain scores despite lower systemic opioid requirements in the early post-operative period.
