PURPOSE
The purpose of this study was to examine the effects of the evidence-based clinical practice guidelines on Postoperative Nausea and Vomiting (PONV).
METHODS
The research design was a non-equivalent control group with a non-synchronized design. The participants were the patients undergoing gynecologic laparoscopy. Data were collected from July, 2014 through January, 2015. The participants in the experimental group (n=35) received an assessment of risk factors of PONV, aroma therapy, and P6 acupressure method as recommended in the guidelines. Those in the control group (n=35) received usual nursing care. Data were analyzed by mean, standard deviation, t-test, chi2-test using SPSS/WIN 19.0 program.
RESULTS
The occurrence of nausea and vomiting, the level of nausea and vomiting, and the need for antiemetic medicine in the experimental group were significantly less than those in the control group after surgery. The levels of postoperative pain and the amounts of time for nursing activities in the experimental group were significantly reduced than those in the control group after surgery. The levels of satisfaction were significantly higher in the experiment group than that of the control group.
CONCLUSION
The evidence-based guidelines is recommended for nursing practice as a guidance for managing PONV and helping the recovery of patients after laparoscopic surgery.

PURPOSE
The study was done to investigate the effect of ethanol inhalation on postoperative nausea in patients using Patient Controlled Analgesia (PCA).
METHODS
The data were collected from June 1st 2006 to September 30th, 2007. The subjects were 70 patients who had had orthopedic surgery under general anesthesia. The levels of the Visual Analogue Scale (VAS) was used to measure postoperative nausea. The experimental group was given ethanol inhalation using ethanol pads and the control group received normal saline pads. All participants were instructed to take two deep sniffs with the pad one inch from the nose. This was repeated every five minutes for three doses. The collected data were analyzed using SPSS/WIN 12.0 program.
RESULTS
The study supported all hypotheses. "The experimental group given first dose of ethanol inhalation would have a lower level postoperative nausea compared to the control group"(t = -5.900, p = .000). "The experimental group given second doses of ethanol inhalation would have a lower level postoperative nausea compared to the control group"(t = -7.507, p = .000). "The experimental group given third doses of ethanol inhalation would have a lower level postoperative nausea compared to the control group"(t = -6.685, p = .000).
CONCLUSION
According to these results, the ethanol inhalation can be considered an effective nursing intervention for relieving the postoperative nausea in patients using PCA.
