Summary

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

Detailed description

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.

Conditions

• Postoperative Pain
• Open Abdominal Surgery

Interventions

Type	Name	Description
PROCEDURE	Bilateral Erector Spinae Plane (ESP) Block	Administered after the induction of general anesthesia and before the surgical incision. Local anesthetic (0.25% ropivacaine or 0.25% bupivacaine) will be injected for a total of 20-40 mL
DRUG	Standard Postoperative Analgesia	Patients receive 1000 mg of IV paracetamol every 6 hours postoperatively. If a patient experiences a Visual Analogue Score (VAS) of more than five at any time, they receive rescue analgesia in the form of nalbuphine 4mg
