Summary

Adequate pain control after cesarean delivery is a major concern both for parturient and for obstetric anesthesiologists, and it usually comprises a combination of systemic and regional techniques.The transversus abdominis plane (TAP) block, affecting the nerves supplying the anterior abdominal wall, is a recently introduced, promising regional analgesic technique for a variety of abdominal and pelvic surgeries including cesarean delivery.(2,3) Infiltration of local anesthetic into the surgical wound (either as a single shot or using indwelling catheters) has long been used for postoperative analgesia.

Both the TAP block (4-6) and wound infiltration is superior to placebo; however, it is unknown which of them provides better analgesia after cesarean delivery because of a scarcity of randomized clinical trials. Only 2 studies compared the TAP block with wound infiltration after cesarean delivery with conflicting results, and another study compared it with continuous wound infusion and was prematurely terminated.

This study aimed to compare bilateral TAP block with single-shot local anesthetic wound infiltration for analgesia after cesarean delivery performed under spinal anesthesia. We hypothesized that the TAP block would decrease postoperative cumulative opioid consumption at 24 hours

Conditions

  • Cesarean Section

Interventions

DRUG

20 mL of bupivacaine 0.25%

In the infiltration group, at the end of surgery, 30 mL of bupivacaine 0.25% was injected subcutaneously in the surgical wound (15 mL in each of the upper and lower sides) by the obstetrician before skin closure. Sam procedure was performed by the primary investigator after completion of surgery by pressing a covered spinal needle on both sides of the patient's abdomen. In the TAP group, after completion of surgery, 20 mL of bupivacaine 0.25% was injected under direct visualization in the plane between the transversus abdominis muscle and the fascia deep to the internal oblique muscle on each side.
