Postoperative Nausea and Vomiting
Conditions
Brief summary
Introduction: Current rates of postoperative nausea and vomiting (PONV) experienced by outpatient surgery patients are as high as 20-30%. Electroacustimulation (EAS) therapy has been demonstrated to be effective in controlling these symptoms, but trials identifying their efficacy in the outpatient surgery population are lacking. This study integrates conventional pharmacotherapy with alternative medicine in prevention of PONV. Materials and Methods: One hundred twenty two patients undergoing surgery procedures at an outpatient surgery center were randomized to two treatment arms. The first arm was standardized pharmacologic PONV prevention typical for patients undergoing outpatient surgery, while the second arm employed the use of ReliefBand, an FDA-approved electroacustimulation (EAS) device with pharmacologic treatment to relieve symptoms of PONV and pain. EAS is a derivative of acupuncture therapy that uses a small electrical current to stimulate acupuncture points on the human body and is thought to relieve nausea, vomiting and pain. Outcomes measured were post-op questionnaires evaluating pain and nausea symptoms, emetic events, the need for rescue medications and the time to discharge.
Interventions
Electroacustimulation (EAS) is a derivative form of acupuncture therapy where a small current of electricity instead of a needle is used to stimulate an acupoint on the human body in an effort to create therapeutic effects.

| Post-operative Nausea Scores | 24 hours | Nausea is scored on a scale of 1-10 where 1 is least nauseated and 10 is severely nauseated. Nausea scores will be collected 30, 60, and 120 minutes after surgery. |
