Review Meta Analysis
Efficiency and safety of ketamine for pain relief after laparoscopic cholecystectomy: A meta-analysis from randomized controlled trials.
This meta-analysis aims to evaluate the effectiveness of intravenous infusion of ketamine for pain control after laparoscopic cholecystectomy (LC). ⋯ Intravenous ketamine infusion significantly reduced postoperative pain scores and opioid consumption after LC. In addition, there were fewer adverse effects in the ketamine groups. Higher quality RCTs are still required for further research.
