Optimization of Post-Operative Therapy for Nausea or Vomiting

Post-Operative Therapy for Nausea or Vomiting


Lead sponsor: University of California, Davis

Source University of California, Davis
Brief Summary

This is a single site, prospective, randomized controlled study designed to evaluate the impact of acupressure when used as an initial treatment before rescue medications in the treatment of post-operative nausea and/or vomiting at UCD.

Detailed Description

Each individual will only participate in the post anesthetic care unit starting from when the patient's nurse or anesthesiology team deems that the patient needs treatment for PONV. It ends when the patient is discharged from anesthesiology care.

Patients will be asked to score nausea before randomized treatment of acupressure or medication, and to score nausea after treatment.

Intervention type: Procedure

Intervention name: Acupressure

Description: Specifically trained personnel will apply pressure on the wrists bilaterally at the P6 point for up to 3 minutes. The P6 point is located three fingerbreadths from the wrist crease on the volar surface of the arm between the palmaris longus and flexor carpi radialis. In the event of failure in the acupressure group, further treatments will be identical to the control group. Since Ondansetron is the standard Post Anesthetic Care Unit treatment, it will be first line rescue therapy except in the case that the patient has received 8mg in the past 6 hours. If needed, further antiemetic pharmacologic treatments may include, but are not limited to, phenergan, metoclopramide, haloperidol, diphenhydramine or propofol at the clinical discretion of the patient's anesthesiology care team.

Arm group label: Acupressure
