Brief summary
The aim is to compare the postoperative analgesic effects of Subcostal Transversus Abdominis Plane Block (S-TAP) versus Rectus Sheath Block (RSB) in patients undergoing laparotomy with midline abdominal incision.
Detailed description
Patients were divided into two randomized groups: Group 1 (S-TAP group, n=30) and Group 2 (RSB group, n=30). All patients will receive the same standard general anesthesia per hospital protocol. All blocks will be applied with the same ultrasonography and block equipment, and by the same physician. All patients will receive Paracetamol 1gr and Dexketoprofen 50mg intravenous (IV) 10 minutes prior to skin closure. After the surgery was completed, patients in Group 1 will receive subcostal transversus abdominis plane block (S-TAP) with 20 mL of 0.25% bupivacaine bilaterally (with a total volume of 40 mL). Patients in Group 2 will receive rectus sheath block (RSB) with 20 mL of 0.25% bupivacaine bilaterally (with a total volume of 40 mL). Routine analgesic procedure consisting of 3x1gr Paracetamol and 2x50mg Dexketoprofen will be followed postoperatively for 24 hours. Numeric Rating Scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hours after the surgery. Tramadol 50mg IV will be administered as a rescue analgesic for all patients if NRS score is equal to or higher than 4. Total Tramadol consumption will be calculated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Numeric Rating Scale (NRS) Scores | Postoperative 24 hours | Numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean the most severe pain that the patient ever had. 0 point means there is no pain. Higher scores mean worse outcome. |
| Total tramadol consumption | Postoperative 24 hours | Postoperative total rescue analgesic need was recorded as milligram in unit. |
