Summary

Midline incisions provide easy, rapid and excellent exposure of the abdominal cavity and are particularly used for complex, diagnostic or emergency procedures.

However, midline incisions transect the nerve fibers passing in the mediocaudal direction of the abdominal wall, which causes more postoperative pain than other incisions.

Postoperative pain and delayed return of bowel function are thought to be the main factors that prevent early recovery and discharge.

or surgical procedures where parietal pain is the main component of postoperative pain, TAPB can be used as a simple and effective analgesic technique with the added advantage of preserved motor and bladder function.

Quadratus lumborum block can be used as an analgesic technique in all surgeries such as proctosigmoidectomy, hip surgery, above-knee amputation, abdominal hernia repair, breast reconstruction, colostomy closure, radical nephrectomy, lower extremity vascular surgery, total hip arthroplasty, laparotomy and colectomy.

Our study aimed to compare the effects of bilateral oblique subcostal TAPB with bilateral QLB2 and QLB3 performed under ultrasound guidance in midline incision laparotomies on total opioid requirement in the first 24 hours postoperatively, early postoperative pain intensity, time to first rescue analgesic requirement, nausea, vomiting and pruritus.

To evaluate this hypothesis, we compared TAPB and QLB in a prospective, randomized, single-center clinical study. The primary endpoint of our study was the comparison of total morphine consumption in the first 24 hours postoperatively.
