Osteopathic Manipulative Treatment for Post-Operative Nausea and Vomiting

Osteopathic Manipulative Treatment (OMT) as Possible Prophylaxis Against Post-Operative Nausea and Vomiting (PONV) in Patients Receiving Inhalational Anesthesia

The purpose of this study is to determine if Osteopathic Manipulative Treatment (OMT) is effective in reducing nausea and vomiting experienced by patients recovering from anesthesia. OMT is a treatment in which the physician places his hands on areas of the body and applies pressure to correct disturbances in one area that may be related to a problem in another area of the body. Osteopathic Manipulative Medicine is a specialty for a physician who uses OMT.

The hypothesis of this study is when OMT is combined with standard-of-care prophylactic anti-emetic therapy in patients following administration of inhalational anesthesia, in comparison to a control group receiving only standard-of-care anti-emetic prophylaxis there will be a reduction in the incidence and severity of PONV.

Study Overview

• Status: Completed
• Conditions: Postoperative Nausea and Vomiting
• Intervention / Treatment: Procedure: Osteopathic Manipulative Treatment

Detailed Description

This research study is a prospective, randomized, single-blinded, controlled, clinical trial under the principal investigator, Hollis King, DO, PhD with the University of North Texas - Health Science Center, Texas College of Osteopathic Medicine. The purpose of this study is to determine the effectiveness of osteopathic manipulative treatment (OMT) as an adjunctive modality to standard medical care for reduction of post-operative nausea and vomiting (PONV). This is the first attempt to study the treatment of PONV utilizing OMM; this study is being conducted as a pilot study

The hypothesis of this study is when OMT is combined with standard-of-care prophylactic anti-emetic therapy in patients following administration of inhalational anesthesia, in comparison to a control group receiving only standard-of-care anti-emetic prophylaxis there will be a reduction in the incidence and severity of PONV.

Two aims will guide this study toward evaluation of the hypothesis:

AIM I: To demonstrate the effect of OMT and standard care on the number of episodes of emesis experienced post-operatively by subjects having undergone anesthesia utilizing inhalational anesthesia (alone or in combination with intravenous anesthetics). All subjects will receive the treatment or "no-treat" protocol to which they are randomized. Data will be collected prior to discharge from the post-anesthesia care unit (PACU) to enumerate the episodes of emesis experienced by each study subject. Subjects will be asked to complete the Ambulatory Surgery-Rhodes Index of Nausea, Vomiting, and Retching (AS-RINVR) 24-48 hours following surgery when a post-study questionnaire is completed.1

AIM II: To demonstrate the effect of OMT and standard care on the intensity of nausea experienced post-operatively by subjects having undergone anesthesia utilizing inhalational anesthesia (alone or in combination with intravenous anesthetics). Following a subject's completion of the treatment protocol (or "no-treat" if so randomized), the nausea visual analog scale (VAS) validated by Boogaerts will be employed at 30 minutes, 1 hour, and 24-36 hours following their post-operative, post-anesthesia treatment protocol. Results will be compared between the control and experimental group for differences.

Osteopathic manipulative medicine (OMM) and OMT seek, in general, to facilitate a more optimal and often faster return to health and homeostasis. Though individuals largely seek out OMT for alleviation of structural and musculoskeletal complaints, its uses have been speculated and discovered to have effects also on physiologic mechanisms. Osteopathic manipulative treatment maneuvers to the head, neck, and upper thoracic spine may impart postulated mechanisms for PONV.3 Successful treatment will be measured by the reduction of PONV, as evaluated on several outcome measures, in a group of subjects receiving post-operative OMT along with standard-of-care treatment over those in the control group only receiving standard-of-care treatment for their PONV. Successful completion of all of the above specific aims will not only validate the hypothesis of this study but will also establish the study's effect and feasibility for future study. Additionally, this pilot study will establish the statistical trends needed to establish effect size data which is needed for power analysis and sample size estimates for future studies.
