Summary

This study looked at whether giving ketamine during surgery and methadone after surgery can prevent a condition called opioid-induced hyperalgesia, where painkillers actually make you more sensitive to pain. 113 adults having open colorectal surgery took part. The goal was to see if this approach reduces the area of increased pain sensitivity around the surgical wound and lowers overall pain and opioid use.
