Regional Anesthesia Abdominal Blocks and Local Infiltration After Cesarean Delivery: Review of Current Evidence

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

OBJECTIVE

To evaluate the effects of transversus abdominis plane (TAP) block on postoperative recovery 24 h after cesarean delivery under general anesthesia.

METHODS

A 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.

RESULTS

The 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.

CONCLUSIONS

Following 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.

Enhanced Recovery after Surgery: Cesarean Delivery

This review summarizes the importance of enhanced recovery after surgery (ERAS) implementation for cesarean deliveries (CDs) and explores ERAS elements shared with the non-obstetric surgical population. The Society for Obstetric Anesthesia and Perinatology (SOAP) consensus statement on ERAS for CD is used as a template for the discussion. Suggested areas for research to improve our understanding of ERAS in the obstetric population are delineated. Strategies and examples of anesthesia-specific protocol elements are included.

Effect of Bilateral Quadratus Lumborum Block Type I on Patient Satisfaction and Incidence of Chronic Postsurgical Pain Following Cesarean Section-A Randomized Controlled Trial

BACKGROUND

Quadratus lumborum block (QLB) provides a reduction in pain scores and opioid consumption after cesarean section (CS). Intrathecal morphine (ITM) is still considered as the gold standard of acute postoperative pain therapy, but it does have some significant side effects. The aim of this clinical study was to evaluate whether performing the quadratus lumborum block type I in patients undergoing CS would be associated with an increased satisfaction of pain therapy and a decreased incidence of chronic postsurgical pain (CPSP).

METHODS

Sixty patients scheduled for elective CS were enrolled. All patients received spinal anesthesia and were randomly allocated to either the QLB group (received bilateral quadratus lumborum block type I with the use of 24 m mL 0.375% ropivacaine) or the control group (received no block). The level of satisfaction was evaluated using a three-step scale and the answers provided in a questionnaire regarding the patients' satisfaction with the method of postoperative pain treatment in the first 48 h. After a 6-month period, all patients were interviewed to evaluate the incidence and possible severity of CPSP.

RESULTS

Satisfaction scores were significantly lower in the QLB group than in the control group (p = 0.0000). There were no significant differences between the QLB and control groups regarding the occurrence of chronic postsurgical pain after 6 months following CS (p = 0.102). No statistical differences between the groups were recorded when we compared the results of the questionnaire after a period of 48 h from CS (the number of participants were limited in number).

CONCLUSIONS

QLB type I is an analgetic option that increased the satisfaction of parturients with pain therapy after CS compared to patients who did not receive the block, and there is a tendency for a lower incidence of CPSP.
