Abstract
Introduction: Postoperative nausea and vomiting (PONV) is a common side effect of all types of surgeries, especially so in bariatric surgery. Dexmedetomidine (DX) is an α2-agonist that may be useful as an adjunct prophylactic medication for PONV. This meta-analysis aims to evaluate the efficacy of DX in reducing the incidence and severity of PONV in laparoscopic bariatric surgeries.
Materials and methods: Databases were searched for articles with the determined MESH terms and keywords before February 2022. Identified articles were screened and 13 randomised clinical trials (RCTs) were included in this meta-analysis based on the inclusion criteria. Data were extracted from the articles and statistical analysis was performed using Review Manager.
Results: Administration of DX significantly reduced the incidence of PONV and Numerical Rating Scale (NRS) scores for PONV. The outcome was probably due to the intrinsic sympatholytic effect of the medication, reduction of postoperative pain and total postoperative opioid usage. DX showed better efficacy as PONV prophylaxis if the duration of surgery was < 120 minutes. Delivery of DX as a continuous infusion without a loading dose before infusion was found to be effective in reducing PONV compared to infusion after a loading dose.
Conclusion: Administration of DX can reduce the incidence of PONV in patients undergoing laparoscopic bariatric surgery. However, further studies are required to investigate the optimal dose of DX as an antiemetic, considering its side effects to increase the applicability of our results in future guidelines for laparoscopic bariatric surgery.
期刊介绍：
Published since 1890 this journal originated as the Journal of the Straits Medical Association. With the formation of the Malaysian Medical Association (MMA), the Journal became the official organ, supervised by an editorial board. Some of the early Hon. Editors were Mr. H.M. McGladdery (1960 - 1964), Dr. A.A. Sandosham (1965 - 1977), Prof. Paul C.Y. Chen (1977 - 1987). It is a scientific journal, published quarterly and can be found in medical libraries in many parts of the world. The Journal also enjoys the status of being listed in the Index Medicus, the internationally accepted reference index of medical journals. The editorial columns often reflect the Association''s views and attitudes towards medical problems in the country. The MJM aims to be a peer reviewed scientific journal of the highest quality. We want to ensure that whatever data is published is true and any opinion expressed important to medical science. We believe being Malaysian is our unique niche; our priority will be for scientific knowledge about diseases found in Malaysia and for the practice of medicine in Malaysia. The MJM will archive knowledge about the changing pattern of human diseases and our endeavours to overcome them. It will also document how medicine develops as a profession in the nation. We will communicate and co-operate with other scientific journals in Malaysia. We seek articles that are of educational value to doctors. We will consider all unsolicited articles submitted to the journal and will commission distinguished Malaysians to write relevant review articles. We want to help doctors make better decisions and be good at judging the value of scientific data. We want to help doctors write better, to be articulate and precise.
