Summary

This study watches 500 adults aged 65 and older who are having major abdominal surgery. It compares those who get an ultrasound-guided nerve block for pain relief to those who get standard pain management. The goal is to see if the nerve block group has fewer lung complications within the first week after surgery. No new treatments are given—the study just observes what happens in regular hospital care.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of patients aged 65 years and older who are scheduled to undergo elective major abdominal surgery under general anesthesia. Eligible participants will be managed in a tertiary care hospital and will be allocated to either a fascial plane block group or a control group receiving standard perioperative analgesia. The study aims to evaluate postoperative outcomes in an elderly surgical population with comparable baseline characteristics.
