Comparative Study Between Ultrasound Guided versus Transperitoneal Transversus Abdominis Plane Block For Cesarean Section Analgesia

Objectives : To compare between transperitoneal guided transverse abdominis plane (TAP) block versus ultrasound (US) guided TAP block. As regards, time of fi rst call of analgesia, patient satisfaction, the amount of additional analgesic needed for 24 h postoperatively, duration of the procedure and complications encountered in each procedure. Background : Pain after caesarean section is often characterized by majority of cases as moderate to severe. TAP block is a recently introduced regional procedure which provide analgesia to anterior abdominal wall, which is guided by US or transperitoneal surgical approach. Methods : Randomized, double-blind research on 70 women who underwent elective caesarean section distributed into two groups each is 35 women. Group ST: transperitoneal guided TAP block was delivered after uterine closure and good hemostasis. Group UT: ultrasound-guided TAP block was done after closure of skin. Results : The fi rst call of analgesia was statistically comparable between both groups ( P ¼ 0.528). Conclusion : Ultrasound-guided and surgical TAP blocks had the same safety and had the same effectiveness in achieving postoperative analgesia after caesarean section.
