Different types of anesthetics have different effects on heart rate variability. However It has not yet been reported whether this difference in effect remains at recovery time after anesthesia.~Several studies have been reported that preoperative heart rate variability predicted the occurence of postoperative nausea and vomiting. However, whether the difference in heart rate variability after anesthesia is related to the difference in postoperative nausea and vomiting has not been studied. Therefore, this study aims to observe whether propofol and sevoflurane have differences during recovery period after anesthesia in heart rate variabiliy. In addition, we want to examine that these differences during recovery period in heart rate variability can predict the occurrence of nausea and vomiting within 24 hours after surgery.

The aim of this study is observe whether propofol and sevoflurane have different effects on heart rate variability during recovery and the differences can predict the occurrence of postoperative nausea and vomiting.
