Postoperative Nausea and Vomiting and Acupuncture/Acupressure

Phase 2

Completed

• Conditions: Postoperative Vomiting; Nausea
• Interventions: Device: Acustimulation

• Registration Number: NCT00965367
• Lead Sponsor: National Research Centre of Complementary and Alternative Medicine, Norway

Brief Summary

Postoperative nausea and vomiting (PONV) remain a significant challenge in the investigators practice. However, pharmaceutical prophylaxis can imply unpleasant adverse effects. It would therefore be appropriate to consider the use of non-pharmacological methods in preventing PONV. Acupuncture and acupressure are reported to be effective preventive treatment for PONV, and the adverse effects are minimal.

Consequently, the investigators will investigate if acupuncture and acupressure can be implemented as a supplementary to the ordinary treatment in children undergoing surgery for tonsillectomy and/or adenoidectomy. The study will also focus on the feasibility for acupuncture and acupressure in the operation theatre. The study and inclusion/exclusion decisions are conducted after the "intention-to-treat" principle. 126 patients are included, divided into two groups:

1. Treatment Group - standard treatment and acupuncture performed after induction of anaesthesia, acupressure administered before awakening

2. Control Group - standard treatment

The primarily endpoints in this study are nausea, retching and vomiting. The effect of acupuncture/acupressure will be studied with regard to any association with possible factors of predisposition to PONV, as well as with other factors registered during the study. Adverse effects from the acupuncture site and wristband will be registered.
