Purpose: The purpose of this study was to quantify the incidence of post discharge nausea and vomiting (PDNV) in patients undergoing general anesthesia for third molar extraction and also identify any risk factors associated with PDNV.Methods: 70 patients were enrolled for this prospective clinical study. The primary endpoint was the incidence of nausea and/or vomiting after discharge from the clinic up to 7 postoperative days. Logistic regression analysis was applied to identify and quantify the impact of relevant risk factors.Results: A total of 42 patients completed the study. The overall incidence of nausea for the study was 56.1% and vomiting was 14.8%. The incidence of nausea on Day 1 was 48.8%. The incidence of nausea decreased to 14.6% on the next day after surgery and 4.8% on Day 7. Females had higher incidence of nausea compared to males but the results were not statistically significant. There was no association between anesthetic medications, history of motion sickness, opioid consumption, antibiotic usage and smoking status and nausea.Conclusion: Post discharge nausea affects a significant number of patients after general anesthesia for third molar extractions. Further studies with larger study populations are needed to identify potential risk factors for post discharge nausea.
