A Quality Improvement Project to Determine the Effect of Aromatherapy on Postoperative Nausea and Vomiting in a Short-Stay Surgical Population.

Postoperative nausea and vomiting (PONV) is a major concern for short-stay surgical patients because it can delay discharge and cause preventable postoperative complications, which in turn can increase hospital costs. Evidence suggests that aromatherapy effectively reduces PONV, either as a monotherapy or in conjunction with pharmacologic antiemetics. This quality improvement project investigated the effectiveness of aromatherapy in reducing PONV in a short-stay surgical population. The outcome of this project supported the hypothesis that the administration of blended aromatherapy would result in a significant decrease in patients' self-reported ratings of nausea. This finding suggests that aromatherapy is an appropriate adjunct therapy for decreasing patient nausea and vomiting in this short-stay surgical unit and may help prevent discharge delays in this population.
