Modified Thoracoabdominal Nerve Plane Block In Living Liver Donors

NCT06300372 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

No results posted yet for this study

Summary

Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed deep 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. As there are studies showing M-TAPA block to be effective for postoperative analgesia for other abdominal surgeries, its effect on patients undergoing living liver donor surgery has not been studied yet. We hypothesize that M-TAPA block performed in living liver donors would reduce opioid consumption in the first 48 hours after surgery.

Conditions

  • Liver Failure
  • Acute Postoperative Pain

Interventions

PROCEDURE

M-TAPA plane block

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 (Pajunk Sonoplex Nanoline Stim Cannula, Germany) 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 bilaterally (60 ml in total).

PROCEDURE

Postoperative pain management

For preemptive analgesia, morphine (Morfin ®) 0.05mg/kg and Ibuprofen 400mg IV (Ibuprofen®) will be administered to all patients before the surgical incision. An additional dose of ibuprofen 400mg IV, meperidine (Aldolan ®), and tramadol (Contramal®) 1mg/kg IV will be administered to all patients 30 minutes before wound closure.10 mcg/ml fentanyl containing PCA will be connected to all patients without infusion and boluses 0,35 mcg/kg,15-minute lockout period, maximum 100 mcg per hour. Postoperative patient evaluation will be performed by another anesthesiologist. If the NRS score is ≥ 4, 0.5 mg/kg IV meperidine (Aldolan®)will be administered as a rescue analgesic.
