Analgesic Effect of M-TAPA on LC

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.
