Combining a nerve block with intrathecal morphine for better pain relief after major abdominal surgery
Official title: Efficacy of Adding Intrathecal Morphine to Erector Spinae Plane Block for Postoperative Analgesia After Midline Laparotomy: A Prospective Randomized Study
Run by Sohag University · NCT07720739 · Data updated 2026-11-12
This study tests whether adding intrathecal morphine to an erector spinae plane block helps adults have less pain and use fewer opioids in the first two days after a midline laparotomy.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are adults (ASA I–III) undergoing elective or emergency midline exploratory laparotomy who can consent and understand pain rating scales.
✕Probably not a fit
Patients with contraindications to regional or neuraxial anesthesia, morphine hypersensitivity, chronic daily opioid use, substance use disorders, or severe respiratory or neurologic conditions may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
In adults undergoing elective or emergency midline laparotomy, researchers compare the combination of an erector spinae plane block with intrathecal morphine to either technique alone for postoperative analgesia. The goal is to determine if the dual approach provides superior pain control and lowers opioid consumption within 48 hours after surgery. The study is interventional and involves neuraxial and regional anesthesia methods, with safety and pain outcomes monitored. Results could influence analgesic strategies for major abdominal surgery.
Why it matters
Potential benefit: If successful, patients may experience better pain control and reduced opioid use after surgery.
How similar studies have gone: Previous research has explored regional blocks and intrathecal opioids separately; combining these approaches is a newer strategy with potential for added benefit.

Inclusion Criteria Patients scheduled to undergo elective or emergency midline exploratory laparotomy. American Society of Anesthesiologists (ASA) physical status I, II, or III. Intact cognitive ability to comprehend study procedures, use the Numeric Rating Scale (NRS) accurately, and provide informed consent. Exclusion Criteria Contraindications to regional or neuraxial anesthesia (e.g., patient refusal, localized infection at needle insertion sites, known coagulopathy (INR \>1.5 or platelet count \<80,000/\\mu L), or un-pausable therapeutic anticoagulation). Known allergy or severe hypersensitivity to local anesthetics or morphine. Chronic pain conditions requiring daily opioid consumption for \>3 months preoperatively. Documented history of substance use disorder. Severe chronic respiratory disease (e.g., COPD requiring home oxygen therapy, or severe obstructive sleep apnea not managed with CPAP). Neurological or psychiatric conditions that compromise sensory perception or communication. Surgical incisions planned to extend significantly past the midline. Severe spinal deformities or a history of spinal surgery at the targeted block/injection interspaces. Concurrent enrollment in any other interventional clinical trial.
