Summary

This study aimed to compare two ways of managing pain during abdominal surgery in people aged 50-70 with isolated systolic hypertension. One method uses opioids, the other uses an epidural. The goal was to see which leads to shorter hospital stays and fewer complications. However, the study was withdrawn before enrolling any participants.
