Clinical Trial Summary

In this study, the postoperative analgesic effect of ultrasound-guided modified thoracoabdominal nerves blocks through perichondrial approach (M-TAPA) and oblique subcostal transversus abdominis plane block(OSTAP) will be searched in patients recruiting for laparoscopic cholecystectomy (LC) and the two groups will be compared in terms postoperative opioid consumption. The primary aim of this study is to compare the effects of ultrasound-guided (M-TAPA) and OSTAP blocks on opioid consumption after LC surgery. It is hypothesized that M-TAPA will reduce opioid consumption of the patients more than the OSTAP block.


Clinical Trial Description

Laparoscopy is a minimally invasive procedure, but postoperative pain is still the most common symptom after laparoscopic cholecystectomy (LC). Oblique subcostal transversus abdominis plane (OSTAP) block is a regional anesthesia technique defined for abdominal surgeries. Previously, several studies have reported that ultrasound-guided OSTAP blocks reduce postoperative pain scores after LC. M-TAPA block is performed by applying local anesthetic to the lower surface of the chondrium. This technique provides effective analgesia in the abdominal wall. 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, M-TAPA and OSTAP blocks will be performed under ultrasound guidance after administering general anesthesia and prior to the skin incision. An anesthesiologist who performed blocks 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, antiemetic, opioid consumption, and Quality of Recovery score will be blinded to group assignment. ;
