Effect of Fresh Gas Flow Differences on Postoperative Nausea and Vomiting

The aim of this study is to investigate the effect of fresh gas flow applied during general anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing septorhinoplasty surgery. Patients who agree to participate in the study will be divided into three groups according to the fresh gas flow applied: low flow (0.5 lt/min) (Group L), medium flow (2 lt/min) (Group M) and high flow (4 lt/min) (Group H), and the postoperative nausea and vomiting data of the groups will be compared.
