Aromatheranv Effective Treatment for Postoperative Nausea

摘要

Patients undergoing surgery with general anesthesia often have the adverse side effect of postoperative nausea. The authors hypothesize that aromatherapy may reduce postoperative nausea. Aromatherapy is appealing because it is (1) noninvasive; (2) anymedical staff or patient can use it; and (3) it costs less than antiemetic medication (i.e., medicines that treat nausea and vomiting). However, it is unknown which aromas or combinations of aromas are effective in reducing postoperative nausea. The purpose of this prospective, 4-arm, placebo-controlled clinical trial was to examine the reduction in severity of post-surgery nausea using several essential oils compared with placebo.
