title: Effectiveness of Ginger Essential Oil on Postoperative Nausea and Vomiting in Abdominal Surgery Patients.
abstract: BACKGROUND
  The purpose of this study was to examine the effectiveness of aromatherapy with ginger essential oil on nausea and vomiting in abdominal surgery patients.
  
  
  METHODS
  This was a quasi-experimental study with a nonequivalent control group and repeated measures. The experimental group (n = 30) received ginger essential oil inhalation. The placebo control group (n = 30) received normal saline inhalation. The level of postoperative nausea and vomiting was measured using a Korean version of the Index of Nausea, Vomiting, and Retching (INVR) at baseline and at 6, 12, and 24 h after aromatherapy administration. The data were collected from July 23 to August 22, 2012.
  
  
  RESULTS
  Nausea and vomiting scores were significantly lower in the experimental group with ginger essential oil inhalation than those in the placebo control group with normal saline. In the experimental group, the nausea and vomiting scores decreased considerably in the first 6 h after inhaled aromatherapy with ginger essential oil.
  
  
  CONCLUSIONS
  Findings indicate that ginger essential oil inhalation has implications for alleviating postoperative nausea and vomiting in abdominal surgery patients.
