The effects of stimulation of acupressure point p6 on postoperative nausea and vomiting: a review of literature.

Author information

  • 1Anesthesiologists Associates PC, Chattanooga, TN, USA.


Postoperative nausea and vomiting (PONV) can complicate and delay patient recovery from general and neuraxial anesthesia. Even with a new generation of anesthetic drugs and antiemetics, a high number of patients are affected by PONV. PONV has a multifactor etiology, but there are ways to reduce its occurrence. Although it is not a traditionally recognized method, stimulation of acupressure points, specifically P6, has been identified as a potentially effective method of reducing PONV. This study is a state of the science paper reviewing research on both pharmacologic and nonpharmacologic prophylaxis and various methods of acupressure. It was conducted to add information to the currently available knowledge regarding PONV in hopes of stimulating the use of acupressure for treatment of PONV. The study is divided into six categories: pathophysiology of PONV, background studies of PONV, nonpharmacologic prophylaxis, pharmacological prophylaxis, acupressure and related techniques, and benefits of routine antiemetic prophylaxis.
