Perioperative Ketamine for Analgesia in Spine Surgery: A Meta-analysis of Randomized Controlled Trials.

ABSTRACT: STUDY DESIGN:A meta-analysis of randomized controlled trials (RCTs). OBJECTIVE:The aim of this study was to evaluate the effectiveness of perioperative supplemental ketamine to reduce postoperative opioid analgesic consumption following spine surgery. SUMMARY OF BACKGROUND DATA:Although low-dose supplemental ketamine has been known to reduce pain after surgery, there is conflicting evidence regarding whether ketamine can be effective to reduce opioid consumption following spine surgery. METHODS:Comprehensive search of PubMed, the Cochrane Central Register of Controlled Trials for prospective RCTs, Web of Science, and Scopus. Patients who received supplemental ketamine were compared with the control group in terms of postoperative morphine equivalent consumption, pain scores, and adverse events. Mean differences (MDs) and 95% confidence intervals (CIs) were used to describe continuous outcomes. Odds ratios (ORs) and 95% CIs were applied to dichotomous outcomes. RESULTS:A total of 14 RCTs comprising 649 patients were selected for inclusion into the meta-analysis. Patients who were administered adjunctive ketamine exhibited less cumulative morphine equivalent consumption at 4, 8, 12, and 24?hours following spine surgery (all Ps??0.05). CONCLUSION:Supplemental perioperative ketamine reduces postoperative opioid consumption up to 24?hours following spine surgery. LEVEL OF EVIDENCE:1.
