Abstract

Introduction: In this retrospective cohort single-institutional study, we report the outcomes of implementing a standardized protocol of multimodal pain management with thoracic epidural analgesia via the acute pain service (APS) for patients undergoing ventral hernia repair with mesh placement and abdominal wall reconstruction.

Methods: The primary outcome evaluated was postoperative 72-h opioid consumption, measured in intravenous morphine equivalents (MEQ). Secondary outcomes included hospital length of stay (LOS) among other outcomes. The two cohorts were the APS versus non-APS group, in which the former cohort had an APS providing epidural and multimodal analgesia and the latter utilized pain management per surgical team, which mostly consisted of opioid therapy. Using1:1 propensity-score-matched cohorts, Wilcoxon signed-rank test was used to calculate the differences in outcomes. A p < 0.05 was considered statistically significant.

Results: There were 83 patients, wherein 51 (61.4%) were in the APS group. Between matched cohorts, the non-APS cohort's median [quartiles] total opioid consumption during the first three days was 85.6 mg MEQs [58.9, 112.8 mg MEQs]. The APS cohort was 31.7 mg MEQs [16.0, 55.3 mg MEQs] (p < 0.0001). The non-APS hospital LOS median [quartiles] was 5 days [4, 7 days] versus 4 days [4, 5 days] in the APS group (p = 0.01).

Discussion: A dedicated APS was associated with decreased opioid consumption by 75%, as well as a decreased hospital LOS. We report no differences in ICU length of stay, time to oral intake, time to ambulation or time to urinary catheter removal.
