Wound Infiltration

ACTIVE COMPARATOR

Cesarean delivery performed under spinal anesthesia (intrathecal bupivacaine 12.5 mg and intrathecal fentanyl 15 µg). At the end of surgery, 30 mL bupivacaine 0.25% will be injected subcutaneously in the surgical wound (15 mL on the upper and lower sides) by the obstetrician before skin suturing. Sham procedure will be performed after surgery. Standard analgesia (ketorolac and paracetamol) and fentanyl patient-controlled analgesia will be administered postoperatively.

Transversus abdominis plane block

EXPERIMENTAL

Cesarean delivery performed under spinal anesthesia (intrathecal bupivacaine 12.5 mg and intrathecal fentanyl 15 µg). After completion of surgery, bilateral ultrasound-guided TAP block will be performed using 20 mL bupivacaine 0.25% on each side. Standard analgesia (ketorolac and paracetamol) and fentanyl patient-controlled analgesia will be administered postoperatively.

Interventions

Performed at the L3-4 or L4-5 interspace using 27- or 25-gauge spinal needle.

Transversus abdominis plane blockWound Infiltration

Bupivacaine 12.5 mg will be administered in the subarachnoid space.

Transversus abdominis plane blockWound Infiltration

Fentanyl 15 µg will be administered in the subarachnoid space.

Transversus abdominis plane blockWound Infiltration

Lower segment cesarean section using the Pfannenstiel incision and exteriorization of the uterus.

Transversus abdominis plane blockWound Infiltration

30 mL bupivacaine 0.25% will be injected subcutaneously in the surgical wound (15 mL on the upper and lower sides) by the obstetrician before skin suturing.

Wound Infiltration

Sham procedure will be performed after surgery by moving the ultrasound probe and pressing a covered spinal needle on both sides of the patients' abdomen.

Wound Infiltration

Bilateral ultrasound-guided TAP block using 20 mL bupivacaine 0.25% on each side. A 7-12 MHz linear array probe and 22-gauge needle will be used. The probe will be placed transversely above the iliac crest in the anterior axillary line and the needle will be introduced in-plane with the probe from medial to lateral.

Transversus abdominis plane block

IV ketorolac 30 mg/8 h starting at the end of surgery.

Transversus abdominis plane blockWound Infiltration

Oral paracetamol 1 gm/8 h starting 4 h after surgery.

Transversus abdominis plane blockWound Infiltration

Intravenous fentanyl: bolus dose = 20 µg, lockout interval = 7 min, 4-h dose limit = 200 µg, with no background infusion.
