Brief summary

Objective: To investigate the postoperative analgesic efficacy of M-TAPA block and its effect on opioid consumption in patients undergoing laparoscopic cholecystectomy (LC) surgery. Place and Duration of Study: Department of Anesthesiology and Reanimaton, Sivas Cumhuriyet University, Sivas, Turkey, from April 2023 to May 2023. Methodology: There were two randomized groups: Group M-TAPA (n=21) and Group Control (no block) (n=21). All patients had standard general anesthesia. Group M-TAPA patients had bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery. Group Control had only tramadol for posteperative pain. Numerical rating scale (NRS) and visual analogue scale (VAS) were used to assess postoperative pain. Total tramadol consumption was calculated.

Interventions

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. Same procedure applied to the contralateral side.

Intervention model description

There were two randomized groups: Group M-TAPA (n=21) and Group Control (no block) (n=21). All patients had standard general anesthesia. Group M-TAPA patients had bilateral M-TAPA block with 0.25% bupivacaine (total volume of 40 ml) at the end of the surgery. Group Control had only tramadol for posteperative pain.

Design outcomes

Primary

MeasureTime frameDescription
numerical rating scale scorespostoperative 24 hoursnumerical 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.
