Summary

Adequate pain control after cesarean delivery is a major concern for both parturients and obstetrician, and it usually comprise 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 .

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 and wound infiltration, are superior to placebo, however, it is unknown which of them provides better analgesia after cesarean delivery because of a scarcity of randomized clinical trials.

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

Conditions

  • Postoperative Pain Control

Interventions

PROCEDURE

Ultrasound-guided transversus abdominis plane (TAP) block 0.25% bupivacaine.

After preparing the skin with antiseptic solution, a linear high frequency ultrasound probe will be placed abdominal wall between the iliac crest and the costal margin. A Spinal needle 22g attached with flexible tubing to a syringe filled with saline will be used to perform the block then introduced through the skin anteriorly in the plane between the internal oblique and transversus abdominis muscles with its tip lying in the mid axillary line. To assist with identifying these structures, The final position of the probe will to be no further anterior than the anterior axillary line. If satisfactory views are not obtained, the TAP block will not be performed. Hydro dissection with saline (2-5 ml) will be used to separate the fascial layers. After aspiration to exclude inadvertent vascular puncture, 20 ml of the 0.25% bupivacaine will be injected . TAP block will be performed in a similar fashion on the opposite side.
