IntroductionThe aim of this systemic review and meta-analysis was to assess the impact of prophylactic use of esketamine on postoperative depression and quality of life in patients.Evidence AcquisitionWe searched for all articles on esketamine in patients after surgury in electronic data bases, including PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, up to the June 2023.The included studies compared the impact of using esketamine and placebo on postoperative depression and quality of life in patients through randomized controlled trials. The outcome measurements consist of postoperative depression and indicators that can reflect the impact on patients' post Cochrane Risk of Bias tool in Review Manager 5.4 tool was adopted to assess the risk of bias.Evidence SynthesisThe study included a total of 11 randomized controlled trials with 1447 participants. This meta-analysis demonstrated that the prophylactic use of esketamine alleviated postoperative depressive symptoms (standardized mean difference [SMD]: -0.61; 95% confidence interval [CI]: -0.96 to -0.25; P=0.0008) and incidence (relative risk [RR]:0.37;95% [CI]: 0.22 to 0.62; P=0.0001), reducing the occurrence of postoperative depression, anxiety, and chronic pain. Additionally, it improved postoperative sleep quality and enhanced the postoperative quality of life for patients.ConclusionsProphylactic use of esketamine during the preoperative and anesthesia period has shown significant benefits in improving postoperative quality of life.
