Modified Thoracoabdominal Nerve Plane Block In Laparoscopic Sleeve Gastrectomy
Evaluation of Effectiveness of Ultrasound-Guided Modified Thoracoabdominal Nerve Plane Block Through Perichondrial Approach (M-TAPA) for Postoperative Analgesia Management in Patients Undergoing Laparoscopic Sleeve Gastrectomy Operation

INTERVENTIONAL
Conditions
Summary
Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed into the costochondral aspect at the 9th-10th costal level by injecting local anesthetics deep into the chondrium. It provides blockage of both the anterior and lateral cutaneous branches of the thoracoabdominal nerve. Studies show that M-TAPA block is effective for postoperative analgesia and other abdominal surgeries, but its effect on patients undergoing LSG surgery has not yet been studied. The hypothesis is that the M-TAPA block performed in patients undergoing Laparoscopic Sleeve Gastrectomy (LSG) Operation would reduce opioid consumption in the first 24 hours period after surgery.

Interventions
After the wound closure is completed and the patient is still under genaral anesthesia the M-TAPA block ill be performed. As the patient is in the supine position, the high-frequency linear US probe (11-12 MHz, Vivid Q) and a 22-G 80-mm needle (Stimuplex® Ultra 360®, Braun, USA) will be placed in a sagittal position at the costochondral junction at the level of the 9th and 10th ribs. After the rib and the external oblique, internal oblique, and transversus abdominis muscles are visualized on USG, using an in-plane technique, the block needle will be advanced and the block location will be confirmed by injecting 5 ml of saline between the internal oblique and transversus abdominis muscles. Once the block location is confirmed, 30 ml of 0.25% bupivacaine (Buvicaine ®) will be applied on each side. The total volume will be 60 ml.
ibuprofen 400mg (Ibuprofen-PF®) intravenous (IV), and tramadol (Contramal®) 100 mg IV will be administered to all patients 20 minutes before wound closure. After surgery, Ibuprofen 400 mg will be given three times a day. A patient-controlled analgesia (PCA) system containing 10 mcg/ml fentanyl will be provided to all patients without continuous infusion. Patients can administer boluses of 0.35 mcg/kg with a 15-minute lockout period and a maximum dose of 100 mcg per hour. Another anesthesiologist will assess patients after surgery. If the patient's pain score (NRS) is 4 or higher, IV tramadol (Contramal®) 100 mg will be given as a rescue analgesic.
