Comparison of the Analgesic Effects of Local Anesthetic Infiltration and Ultrasound-Guided Rectus Sheath Block in Laparoscopic Cholecystectomy Operations: A Prospective Randomized Controlled Study

Laparoscopic cholecystectomy is a very commonly performed and painful surgical procedure. The etiology of pain is complex and commonly includes pain related to trocar insertion sites, pain secondary to carbon dioxide insufflation, visceral pain, and shoulder pain. Various analgesic medications and regional anesthesia techniques are used for postoperative pain management. Abdominal wall blocks are frequently utilized to reduce opioid-related adverse effects.

Rectus sheath block is a regional anesthesia technique that blocks the anterior cutaneous branches of the lower thoracic nerves (T7-T12) and is used for analgesia in laparoscopic surgeries. Several studies have demonstrated that local anesthetic infiltration provides effective analgesia in laparoscopic cholecystectomy. Although rectus sheath block is an old technique traditionally used in midline surgeries, its analgesic use in laparoscopic procedures has increased in recent years.

In this prospective randomized clinical trial, we aimed to compare the effects of Local Anesthetic Infiltration and Rectus Sheath Block on opioid consumption and pain scores in laparoscopic gallbladder surgery.
