Aim is to compare the postoperative analgesic efficacy of M-TAPA block and TAP block and their effect on opioid consumption in patients undergoing open total abdominal hysterectomy (TAH) surgery.
There were three randomized groups: Group M (M-TAPA block) (n=15), Group T (TAP block) (n=15) and Group C (no block) (n=15). All patients had standard general anesthesia. Group M had bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery. Group T patients had TAP block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery. Group Control had only tramadol for postoperative pain. Numerical rating scale (NRS) was used to assess postoperative pain on 1st, 6th, 12th and 24th hour after the surgery. Total tramadol consumption was calculated.

|---|---|---|---|
| M-TAPA block | Active Comparator | Patients had bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery for postoperative pain control. |
|
| TAP block | Active Comparator | Patients had bilateral TAP block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery for postoperative pain control. |
|
| Control | No Intervention | Control group patients were not subjected to any block or local infiltration anesthesia. Their postoperative pain was relieved with tramadol (intravenous) administration. |

| M-TAPA block | Other | Following sterile conditions for bilateral M-TAPA block application, the transducer was inserted on the chondrium in the sagittal plane at the 9-10th rib level. Subsequently, a deep angle was created with the probe for visualization of the underside of the costochondrium. The sonovisible needle tip was placed just below the chondrium and saline (5 ml) was injected for site confirmation. After the confirmation, 20 ml of 0.25% bupivacaine was administered for each group for a total of 40 ml of local anesthetic. Blocks were applied using an 80 mm sonovisible needle with a 6-10 MHz linear probe under the guidance of a portable ultrasound. M-TAPA block with the same standard technique and drug dose was applied to the contralateral side for each group of M-TAPA patients. |

| Comparing the numerical rating scale scores | 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. | Postoperative 24 hours |

| TAP block | Other | After the necessary sterilization conditions were established, the linear ultrasound probe was sterilely coated and placed in the middle of the iliac crest with the end limit of the ribs. Starting with skin, the layers in descending order, subcutaneous adipose tissue, external oblique muscle, internal oblique muscle, transversus abdominis muscle, and peritoneum were identified. As the tip of the 80 mm sonovisible needle passed through the muscular layers and fascia, a fascial click was felt and the needle was advanced with ultrasound in a controlled manner. After receiving the second click sensation (passage of the fascia of the internal oblique muscle), the location of the needle was fixed and frequently aspirated and applied to the plane so that 20 ml of 0.25% bupivacaine was applied to each side. (40 ml in total) |
