Key take away

Compared to local wound infiltration, TAP block efficiently decreased postoperative pain and total 24-hour postoperative opioid and analgesic consumption in women who underwent C-section.

Background

A randomized controlled double-blinded clinical trial aimed to compare the pain-reducing effectiveness of transversus abdominis plane (TAP) block and Wound site Infiltration following C-section under spinal anesthesia.

Method

All patients received an explanation of the US-guided TAP block or local wound site Infiltration procedure, as well as instruction on how to utilize the visual analogue scale (VAS). Following clearance from the medical ethics committee, 198 randomly chosen patients (gestational age ≥ 37 weeks) between the age of 19-40 years and  were enrolled in the research. Participants were segregated into the TAP group, Wound site infiltration group, and Control group with 66 subjects in each group.

Result

Patients with TAP block had considerably lower pain scores for 12 to 16 hours after surgery compared to those with wound site infiltration, as shown in Figure 1:

People with TAP block required cumulative less analgesia in the first 24 hours.

Conclusion

Bilateral TAP block is more effective than wound site infiltration for postoperative pain alleviation and reduction in total 24-hour postoperative opioid and analgesic intake in women who had cesarean delivery under spinal anesthesia. TAP block yielded longer-lasting and more efficient analgesia.
