Ultrasound-guided Bilateral Modified-thoracoabdominal Nerves Block Through a Perichondrial Approach in Patients Undergoing Laparoscopic Cholecystectomy
Ultrasound-guided Bilateral Modified-thoracoabdominal Nerves Block Through a Perichondrial Approach in Patients Undergoing Laparoscopic Cholecystectomy
This study will define the postoperative analgesic effect of ultrasound-guided bilateral modified-thoracoabdominal nerves block through perichondrial approach (M-TAPA) and compare the control group in patients undergoing laparoscopic cholecystectomy.
Laparoscopic cholecystectomy is the most common laparoscopic procedure and causes moderate to severe postoperative pain. The M-TAPA block was described by Tulgar et al. for postoperative analgesia of abdominal surgeries. However, studies showing the analgesic efficacy of this block are lacking. In this prospective interventional trial, the investigators aim to define the efficacy of M-TAPA block for laparoscopic cholecystectomy surgeries under general anesthesia.
This study will be conducted as a single-center, prospective, randomized, double-blinded trial in a university hospital. Patients scheduled for elective laparoscopic cholecystectomy will be screened for enrollment in the study. After randomization, the patients in the Group M-TAPA will receive bilateral M-TAPA block at the beginning of the operation defined by Tulgar et al or no intervention (Group N). An anesthesiologist who performed M-TAPA block will not involve in the data collection. Other health care workers who will involve in the evaluation of postoperative pain scores, vital parameters, nausea and vomiting, anti-emetic and opioid consumption will be blinded to group assignment.
