Transversus abdominis plane block improves postoperative recovery following cesarean delivery under general anesthesia: A propensity score matched retrospective cohort study

Abstract

AbstractObjectiveTo evaluate the effects of transversus abdominis plane (TAP) block on postoperative recovery 24 h after cesarean delivery under general anesthesia.MethodsA propensity‐score‐matched, retrospective cohort study was used. A total of 173 pregnancies resulting in elective cesarean delivery under general anesthesia between March 2021 and March 2022 were analyzed retrospectively. Patients receiving TAP block were compared with those receiving only intravenous analgesia. The Quality of Recovery 15 (QoR‐15) score, assessed 24 h postoperatively using a 15‐item questionnaire, was the primary outcome. Secondary outcomes included time to first ambulation, time to first flatus postoperatively, ability to tolerate ambulation, visual analog scale (VAS) score, hospitalization cost, and postoperative nausea and/or vomiting.ResultsThe total QoR‐15 score 24 h postoperatively in the TAP group was significantly higher than in the Control group (P < 0.001). Patients in the TAP group had higher Bruggemann comfort scale scores (P < 0.001), could better tolerate early postoperative ambulation (P < 0.001), and had shorter time to first ambulation (P < 0.001) and flatus (P < 0.001). Correlation analysis demonstrated an inverse relationship between the cumulative VAS pain scores, time to first postoperative ambulation, time to first flatus, and total QoR‐15 score 24 h postoperatively.ConclusionsFollowing cesarean delivery under general anesthesia, TAP block combined with intravenous analgesia can improve postoperative recovery and shorten the time to postoperative ambulation and recovery of intestinal function.
