Transversus Abdominis Plane Block Versus Wound Infiltration for Analgesia After Cesarean Delivery

"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."
