Laparoscopic gynecological surgery causes postoperative pain.The primary objective of this study is to compare the effect of ultrasound (US)-guided oblique subcostal transversus abdominis plane block (OSTAP) on 24-hour total analgesic consumption with transmuscular quadratus lumborum block (TQLB).
Patients between the ages of 18-65, who will undergo laparoscopic gynecological surgery, American Society of Anesthesiologists (ASA) class I-II-III, Body Mass Index (BMI) in the range of 18-25 kg/m², and who will use 3 or 4 trocar for surgery will be included in the study. Patients will be randomized into two groups. OSTAP block will be performed for OSTAPB group and TQL block will be performed for TQLB group. Patients will be administered postoperative 4x500 mg iv paracetamol as needed (if Visual Analogue Scale (VAS) score is 4 or higher). If the VAS score remains at 4 or higher 30 minutes after paracetamol administration, 1 mg/kg iv tramadol will be administered as a rescue analgesic (with a daily maximum dose of 400 mg). The primary outcome is to compare the total analgesic consumption within the first 24 hours after surgery. The secondary outcome is to compare the time to the first postoperative analgesic requirement, VAS scores at rest and on movement, and assess the impact of these two blocks on the quality of recovery using the QOR-15 scale

Postoperative 24 hours total analgesic consumption
The primary outcome is to compare the total consumption of paracetamol and tramadol within the first 24 hours after surgery.
Time frame: 24 hours postoperatively
The time to the first analgesic requirement, VAS scores and QOR-15 scores of the patients
The secondary outcomes are to compare the time to the first postoperative analgesic requirement, VAS scores at 0, 30th min and 1, 2, 6, 12, 18, 24th hours at rest and on movement, and assess the impact of these two blocks on the quality of recovery using the QoR-15 scale. A visual analogue scale (VAS) requires the patient to rate their pain on a scale of 0-10, where 0 represents no pain and 10 represents the worst pain imaginable. The QoR-15 scale is a unidimensional measurement of quality of recovery measured in five domains: physical comfort, pain, physical independence, psychological support, and emotional state. The QoR-15 scale provides a score ranging from 0 to 150, with a high score indicating a good quality of recovery.
Time frame: 24 hours postoperatively
