Comparison of Quadratus Lumborum Block 2 and Transversus Abdominis Plan Block for Postoperative Analgesia in Abdominal Surgery

In abdominal surgeries, USG guided Quadratus Lumborum 2 blocks are performed for postoperative analgesia. For this purpose, Quadratus Lumborum Block 2 (QLB 2) are frequently used blocks.

The aim to this study was to evaluate the postoperative analgesia of preoperative trunk blocks, intraoperative hemodynamic changes with the unblocked control group, Modified Aldrete Recovery Score (MADS) 9 in the recovery unit, Numerical pain scale (NRS) in the service department, It is aimed to examine and compare the time it reaches on the 1st, 2nd and 24th hours after this period. Patient satisfaction is also evaluated in the ward.

In abdominal surgeries, USG guided TAP blocks are performed for postoperative analgesia. For this purpose, TAP blocks are frequently used blocks.

The aim to this study was to evaluate the postoperative analgesia of preoperative trunk blocks, intraoperative hemodynamic changes with the unblocked control group, Modified Aldrete Recovery Score (MADS) 9 in the recovery unit, Numerical pain scale (NRS) in the service department, It is aimed to examine and compare the time it reaches on the 1st, 2nd and 24th hours after this period. Patient satisfaction is also evaluated in the ward.

There was no intervention. All patients will receive pre-oxygenation with O2 100% for 3 min. Anesthesia will be induced by using fentanyl 1μg/kg, propofol 1.5-2 mg/kg, and atracurium 0.5 mg/kg will be used for muscle relaxation. Anesthesia will be maintained by controlled ventilation with oxygen and air (50:50) with the target of EtCO2≈ 35-40 mmHg, isoflurane 1:1.5 minimum alveolar concentration (MAC). Anesthesia will be discontinued and tracheal extubation will be done once the patient fulfills the extubation criteria.Tramadol 100 mg i.v. Before 15 min end of surgery. The patient control analgesia device will administer all patients.
