Review Meta AnalysisTopical application of ketamine to prevent postoperative sore throat in adults: a systematic review and meta-analysis.
Postoperative sore throat is a leading undesirable postoperative outcome. Ketamine is an N-methyl-d-aspartate receptor antagonist and its topical application is used for chronic pain and oral/throat indications. We conducted a systematic review to assess the efficacy of preoperative, topical ketamine application for preventing postoperative sore throat. ⋯ Preoperative, topical ketamine application may be more effective than non-analgesic methods in preventing postoperative sore throat. The number of studies did not suffice to determine the place of topical ketamine among agents to prevent postoperative sore throat.
