The role of postoperative ketamine infusion in ERAS protocols following elective open abdominal surgeries, a systematic review and meta-analysis

Postoperative ketamine infusion within ERAS protocols appears effective in reducing both pain and opioid consumption without significantly impacting PONV or adverse effects. These findings suggest ketamine may be a valuable adjunct in ERAS for elective open abdominal surgeries, though variability in results indicates that optimal dosing and administration strategies require further investigation to maximize patient recovery benefits and minimize side effects.
