NCT07552701

Brief Summary

Laparoscopic cholecystectomy (LC) can cause moderate-to-severe postoperative pain from visceral, referred shoulder, and incisional sources. Multimodal analgesia is recommended, but opioids carry significant side effects. Ultrasound-guided interfascial plane blocks offer a safe alternative. The Modified Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA) blocks T5-T12 dermatomes, while the Recto-Intercostal Fascial Plane Block (RIFPB) provides sensory blockade across the upper anterolateral abdomen. This study compares the postoperative analgesic efficacy of bilateral M-TAPA versus bilateral RIFPB in patients undergoing LC.

Study Arms (2)

M-TAPA Group

ACTIVE COMPARATOR

M-TAPA Group: Patients receiving ultrasound-guided bilateral Modified Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA) using 20 ml of 0.25% bupivacaine per side, applied at the 10th rib level beneath the costochondral perichondrium after surgery while under anesthesia.

Procedure: M-TAPA Group

RIFPB Group

ACTIVE COMPARATOR

RIFPB Group: Patients receiving ultrasound-guided bilateral Recto-Intercostal Fascial Plane Block (RIFPB) using 20 ml of 0.25% bupivacaine per side, injected into the interfascial plane between the rectus abdominis muscle and the 6th-7th costal cartilages just below the xiphoid process, applied after surgery while under anesthesia.
