Brief Summary

Laparoscopic cholecystectomy is one of the most frequently performed procedures and has a short postoperative hospital stay. Even though laparoscopic cholecystectomy results in less postoperative pain than open cholecystectomy, severe pain is a common complaint, particularly in the first 24 hours. The effectiveness of ultrasound-guided inter-fascial plane blocks has recently come to the fore in the field of regional anaesthesia and pain management.

This study will be a randomized double-blinded clinical study to compare the postoperative analgesic efficacy of ultrasound guided bilateral modified thoracoabdominal nerve block through perichondrial approach and ultrasound-guided bilateral external oblique intercostal plane block in patients undergoing elective laparoscopic cholecystectomy.

After approval from the research ethics board of RIMS, Imphal, a total number of 58 patients (18-65 years, ASA I and II, BMI < 30kg/m2) will be randomized into one of the two groups (n=29) after taking written informed consent from the patients. Following anaesthesia induction and patient intubation, group M-TAPA will receive a modified thoracoabdominal nerve block through a perichondrial approach with 20ml of inj. Ropivacaine 0.25% bilaterally and group EOIPB will receive an external oblique intercostal plane blocks with 20ml of Inj. Ropivacaine 0.25% bilaterally.

Postoperatively patients will be shifted to PACU, where the assessment of VRS scores, will be recorded at designated periods. Total analgesic consumption up to 24 hours, and time of first rescue analgesia will be recorded. Data will be recorded in a proforma tabulated in the EXCEL software and analyzed using IBM SPSS Version 26 software. A p-value of less than 0.05 will be taken as statistically significant.
