Research Abstract |
Postoperative nausea and vomiting is one of the most common complications, but its mechanism is unknown. In the present study, we studied the c-Fos expression in the area postrema for the purpose of investigating whether intraoperative hypotension causes postoperative nausea and vomiting. Hypotension significantly increased c-Fos expression in the area postrema of the rats received isoflurane or propofol anesthesia. Although we could not confirm the evidence by behavioral experiments, it is possible that nervous excitement in the area postrema by intraoperative hypotension causes nausea and vomiting.
