TAP Block vs LAWI for Analgesia Post-cesarean Section
Study Details
Study Description
Brief 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

Active Comparator: TAP block group 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. |
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.

Active Comparator: LAWI group 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 |
Procedure: 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 Measures
Primary Outcome Measures
- degree of pain at rest and on movement (hip flexion and coughing) at 2, 4, 6, 12, and 24 hours postoperatively [24 hours]
, 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).
Secondary Outcome Measures
- measures the time to the first postoperative opioid dose [24 hours]
- cumulative opioid consumption at 2, 4, 6, and 12 hours. [12 hours]
