Summary

This trial tests whether combining two pain-relief methods—a nerve block (erector spinae plane block) and a low-dose spinal morphine injection—works better than either alone for patients recovering from major midline abdominal surgery. The goal is to see if the combo improves pain control and cuts down on opioid use in the first 48 hours after surgery. The study enrolls adults scheduled for elective or emergency laparotomy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: intrathecal morphine and erector spinae plane block
What this could lead to: If it works, this combination could offer better pain relief and reduce the need for strong opioids after major abdominal surgery.
What could go wrong: This is a small, early-stage trial, so results may not apply to all patients. Adding spinal morphine carries risks like itching, nausea, or breathing problems.
