his randomized controlled trial aims to evaluate the efficacy of the bilateral erector spinae plane (ESP) block in reducing postoperative opioid consumption in patients undergoing open abdominal surgeries under general anesthesia

Patients undergoing abdominal surgeries experience severe postoperative pain. Conventional pain management methods, including opiates, may pose significant side effects. This study addresses the imperative need for optimizing postoperative pain management by systematically investigating the analgesic effects and complications associated with the bilateral ESP block. The study involves 46 patients allocated into two groups using a lottery method: a control group receiving standard pain control treatment, and an erector spinae block group receiving a bilateral ESP block in addition to standard pain control treatment. Pain intensity will be evaluated using a visual analogue scale (VAS) at 4, 8, 12, and 24 hours after the operation.
