Official title

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

Overview

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.

Detailed description

LSG is defined as first-line bariatric surgery for patients at high surgical risk with better surgical outcomes. Effective postoperative pain management is essential for early mobilization, and reduction of the risk of morbidity and mortality. Opioids, due to their potent analgesic effects are used as a component of multimodal analgesia in the postoperative period. Despite their advantages, opioids may be related to pulmonary complications such as atelectasis and impaired alveolar gas exchange, apnea; postoperative delayed recovery due to ileus, nausea, and vomiting; and prolonged hospital stay. The use of interfascial plane blocks for pain management has increased recently, as ultrasonography (USG) has become a part of daily routine. Interfascial plane blocks provide effective postoperative analgesia.

Additionally, reducing postoperative opioid consumption helps to provide hemodynamic stability and promote early mobilization. Studies are showing M-TAPA block to be effective for postoperative analgesia for abdominal surgeries, and some studies continued comparing its effect in laparoscopic sleeve gastrectomy with other plane blocks. There are also case reports showing the effectiveness of the M-TAPA block in LSG patients. M-TAPA block's effect on LSG patients has not been studied yet. The investigators hypothesize that the M-TAPA block performed in patients undergoing laparoscopic sleeve gastrectomy would reduce opioid consumption in the first 24-hour period after surgery.

Interventions

  • Procedure M-TAPA block
    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
  • Procedure Postoperative pain management
    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

Primary outcome measures

  • Opioid consumption [Time frame: Changes from baseline opioid consumption at postoperative 0, 2, 4, 8, 16, and 24 hours]
Secondary outcome measures (3)
  • Pain scores [Time frame: Changes from baseline pain scores at postoperative 0, 2, 4, 8, 16 and 24 hours]
  • Need for rescue analgesia (tramadol) [Time frame: Postoperative 24-hour period]
  • Adverse events [Time frame: Postoperative 24-hour period]
