Abstract
INTRODUCTION: Post-operative nausea and vomiting (PONV) are a common post-operative problem in anesthesia. The incidence of PONV in patients undergoing cesarean sections is very high. Post-operative nausea and vomiting have many negative impacts on the patient, baby, family, and health care system. Therefore, appropriate evidence-based knowledge regarding the prevention and management of PONV for those high-risk patients is a timely and very important issue to address to decrease the associated complications. METHODS: A comprehensive literature search was conducted in Pubmed/Medline, Cochrane reviews, and google scholar including those studies published in the English language from 2010 up to 2021. The methodological quality of the included studies was appraised by the Cochrane risk of a biased assessment tool for intervention and non-interventional studies. RESULT: The search strategy identified a total of 10,540 articles from different electronic databases. 33 articles were selected for screening after duplicates were removed; finally, 17 articles were included for critical appraisal and 16 articles were excluded with reasons. The included articles consist of 15 RCT, 1 non-control prospective cohort, and 1 cross-sectional study. CONCLUSION: Pieces of evidence revealed that all obstetrics patients undergoing cesarean section should be given multimodal PONV prophylaxis. It is shown that a multimodal approach by a combination of different antiemetic agents should be preferred and most effective in preventing intraoperative and postoperative nausea and vomiting for patients undergoing cesarean section because of the complex pathophysiology of nausea and vomiting.
