Subcostal Transversus Abdominis Plane Block
Sponsor: Esencan Hospital
Summary
This non-randomized controlled study evaluated the efficacy of a right-sided unilateral Transversus Abdominis Plane (TAP) block for postoperative pain management in 60 adult patients undergoing elective laparoscopic cholecystectomy. Participants were equally divided into a control group receiving standard care and an intervention group that received an ultrasound-guided TAP block using 0.25% bupivacaine prior to extubation. While all patients received scheduled paracetamol and dexketoprofen, tramadol was administered as a rescue analgesic for resting pain scores of 5 or higher. The study's primary goal was to compare postoperative pain using the Verbal Numerical Rating Scale (VNRS) at 0, 6, 12, and 24 hours, with secondary outcomes tracking total rescue tramadol consumption, surgical variables, and postoperative complications to determine the TAP block's overall clinical benefit.

TAP Block
The TAP block was performed during the post-anesthesia phase before extubation. The procedure involved the use of an ultrasound system and a linear ultrasound transducer. To perform the TAP block, the linear probe was positioned 2 cm below the xiphoid to locate the rectus abdominis muscle and fascia. Moving the probe in a downward and lateral direction, the external oblique, internal oblique, and transversus abdominis muscles and fascia were identified over the oblique subcostal angle. A 1-2 ml dose of 2% lidocaine was then applied at the insertion site of the peripheral block needle. With the probe in the oblique subcostal position, the peripheral block needle was carefully advanced along the fascia of the transversus abdominis and internal oblique muscles, from the medial to the inferolateral area of the probe.
