|Official Title:||Postoperative Nausea/Vomiting and Acupressure Can Acupressure With Wristbands Reduce the Use of Antiemetics for the Treatment of Postoperative Nausea and Vomiting?|
- Effectiveness of acupressure for postoperative nausea in terms of less use of antiemetic drugs [ Time Frame: one year ] [ Designated as safety issue: Yes ]
Study the effectiveness of acupressure for nausea in all surgical patients undergoing surgery at the Lovisenberg Diakonale hospital.
Effectiveness is monitored by the use of antiemetic drugs compared to a similar period before the wristbands were introduced as standard care at the hospital.
- Reduction in use of antiemetic medication as a consequence of the introduction of acupressure wristband [ Time Frame: One year ] [ Designated as safety issue: No ]
The study will be conducted with a one-group pretest-posttest design, measuring the consumption of antiemetics during a three month period before the implementation (baseline), and during the implementation period. The numbers of surgical operations will be the denominator in the two fractions.
This secondary outcome might also be regarded as the primary outcome as the amount of antinausea medication is the major outcome measure

Nausea and vomiting after surgery and anaesthesia are inconvenient and undesirable physiological and psychological events. In addition to causing distress and discomfort for the patient, retching and vomiting can increase the risk of pain and bleeding, resultant resource use, and prolong stay at the postoperative ward and hospital. The mechanisms behind Postoperative nausea and vomiting (PONV) are complicated, and many of the trigger factors are still unknown. Several types of pharmaceutical antiemetics are in use, but drug therapy is only partially effective in preventing or treating PONV. In 2008 we conducted a trial to assess the effectiveness of acupuncture and acupressure (acustimulation) in reducing postoperative retching and vomiting in children undergoing tonsillectomy and/or adenoidectomy. The results were promising, and the article is published in Acupuncture in Medicine in March 2011.
Cochrane systematic reviews show the effect of acupuncture and acupressure in postoperative antiemetic treatment. The reviews show no clear difference in the effectiveness of P6 acupoint stimulation for adults and children, or for invasive and non-invasive acupoint stimulation. Moreover, there was no reliable evidence for differences in risks of postoperative nausea or vomiting after P6 acupoint stimulation compared to antiemetic drugs.
Aim and objective:
Acupressure wrist bands are less expensive compared to most antiemetics, and the adverse effects of acupoint stimulation are minimal. Accordingly, a reduction in cost-benefit by the use of wristband, is apparent. Considering the results from earlier research along with the promising results from our trial, we are encouraged to implement acupressure into our standard anaesthetic procedures. A reduction of the use of antiemetics will be a parameter on the effectiveness of acupressure.
The aim of this quality improvement study is to implement acupressure as a supplement to the ordinary prophylactic treatment of PONV in our hospital. The objective is to observe whether use of acupressure wristbands reduces the consumption of antiemetics for the treatment of postoperative nausea and vomiting.
