Choosing the type of anesthesia in surgery is affected by intervention of many factors including adverse effects associated with anesthesia. Of these factors Post Operative Nausea and Vomiting (PONV) can be mentioned, which is the most common complication anesthesia professionals deal with that sometimes leads to other serious complications. Thus, choosing of appropriate anesthetic technique seems necessary to reduce the harmful effects of nausea and vomiting after surgery. In this study, by determining the most important risk factors, it is tried to identify patients with a high risk of developing PONV for prophylactic treatment and thus improve the quality of care parents receive. A total of 60 patients 20-60 years (30 males and 30 females) and in class 2 or 1 ASA were selected and randomly divided into two equal groups of 30. A group underwent regional anesthesia and the other general anesthesia. After surgery, during the first 24 hours were evaluated patients were analyzed for nausea and vomiting. The data were analyzed in SPSS software and the occurrence of nausea and vomiting in these two methods of anesthesia were compared. A significant difference was observed between the incidence of nausea and gender (P=0.01). Thus, the incidence of nausea after surgery in women was more than in men. However, there was no significant difference between the incidences of nausea, average age, smoking, BMI, blood pressure, and type of anesthesia. Moreover, in this study, according to a review of PONV in patients at the beginning of the recovery, 6 hours and 24 hours later, it was concluded that in the first 6 hours after inguinal hernia repair surgery this complication occurs more. In agreement with previous studies, gender and type of anesthesia are of the risk factors while age and body mass index were not of the main risk factors. About smoking, it appears that the differences between this study results with the majority of papers is due to differences in methods and precision in asking. https://biomedpharmajournal.org/vol8no2/comparison-of-the-occurrence-of-nausea-and-vomiting-following-general-and-regional-spinal-anesthesia-after-inguinal-hernia/ Nausea and vomiting after surgery General anesthesia Regional anesthesia
