Efune PN, et al. - The incidence of postdischarge nausea and vomiting in day surgery patients was determined in this prospective observational study. Researchers also investigated demographic, intraoperative, and postoperative variables that impact the risk. The reported incidence of postdischarge nausea and vomiting was 14%. An increase in the risk was noted due to intraoperative and postdischarge opioids. The risk was further accentuated because of long-acting intraoperative opioids.
