Clinical Trial Summary

Adequate pain control after cesarean delivery is a significant concern both for parturients and obstetric anesthesiologists. Transversus Abdominis Plane (TAP) block and local Wound infiltration with anesthetics are alternatives for reducing the severity of pain, total analgesic consumption, and opioid side effects. Both the TAP block and wound infiltration are superior to placebo; however, it is unknown which provides better analgesia after cesarean delivery because of a scarcity of randomized clinical trials. So, we hypothesized that the TAP block would decrease postoperative pain and postoperative cumulative opioid consumption at 24 hours

Intervention

Procedure:
• Transversus Abdominis Plane Block
A 22-gauge spinal needle was introduced from medial to lateral in-plane to the ultrasound probe, and 20 mL of bupivacaine 0.25% was injected under visualization in the plane between the transversus abdominis muscle and the fascia deep to the internal oblique muscle on each side.
• Local anesthetic wound infiltration
40 mL of bupivacaine 0.25% was injected subcutaneously into the surgical wound (20 mL on each of the upper and lower sides) by the obstetrician before skin closure

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	degree of pain at rest and on movement (hip flexion and coughing) at 2, 4, 6, 12, and 24 hours postoperatively	, using a visual analog scale (VAS) score for pain intensity reported on 0-10-point scale for analysis. (0 = no pain and 10 = the worst possible pain).	24 hours
Secondary	measures the time to the first postoperative opioid dose		24 hours
Secondary	cumulative opioid consumption at 2, 4, 6, and 12 hours.		12 hours
