Abstract

Objective: Randomized controlled trials indicate regional anesthesia (RA) improves postoperative outcomes with reduced pain and opioid consumption. Therefore, we hypothesized children who received RA, regardless of technique, would have reduced pain/opioid use in routine practice.

Methods: Using a retrospective cohort, we assessed the association of RA with perioperative outcomes in everyday practice at our academic pediatric hospital. Patients 18 years or below undergoing orthopedic, urologic, or general surgeries with and without RA from May 2014 to September 2021 were categorized as single shot, catheter based, or no block. Outcomes included intraoperative opioid exposure and dose, preincision anesthesia time, postanesthesia care unit (PACU) opioid exposure and dose, PACU antiemetic/antipruritic administration, PACU/inpatient pain scores, PACU/inpatient lengths of stay, and cumulative opioid exposure. Regression models estimated the adjusted association of RA with outcomes, controlling for multiple variables.

Results: A total of 11,292 procedures with 3160 RAs were included. Compared with no-block group, single-shot and catheter-based blocks were associated with opioid-free intraoperative anesthesia and opioid-free PACU stays. Post-PACU (ie, while inpatient), single-shot blocks were not associated with improved pain scores or reduced opioid use. Catheter-based blocks were associated with reduced PACU and inpatient opioid use until 24 hours postop, no difference in opioid use from 24 to 36 hours, and a higher probability of use from 36 to 72 hours. RA was not associated with reduced cumulative opioid consumption.

Discussion: Despite adjustment for confounders, the association of RA with pediatric pain/opioid use outcomes was mixed. Further investigation is necessary to maximize the benefits of RA.
