Virtual Reality for Pain Management During High‐Resolution Manometry: A Randomized Clinical Trial

Abstract

ObjectiveHigh‐resolution esophageal manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. HRM is typically performed in the office with local anesthesia only, and many patients find it unpleasant and painful. The aim of this study was to examine the effects of the use of a virtual reality (VR) headset on pain and anxiety outcomes in patients with dysphagia undergoing HRM.MethodsPatients with dysphagia were prospectively recruited and randomized to undergo HRM with and without VR distraction. Data collected included the State‐Trait Anxiety Inventory‐6 (STAI‐6), the Short‐Form McGill Pain Questionnaire, heart rate, and galvanic skin response (GSR) tracings.ResultsForty subjects completed the study, including 20 subjects in the intervention arm and 20 in the control arm. There was evidence of a significant positive effect of VR on calmness (p = 0.0095) STAI‐6 rating, as well as on physiologic measures of pain with significantly decreased GSR rise time (p = 0.0137) and average rate of change of conductance change (p = 0.0035).ConclusionThe use of VR during HRM catheter insertion increased calmness compared to control. Change of skin conductance was also reduced in the VR group, suggesting decreased physiologic pain. This study supports the consideration of the use of VR as a distraction tool to improve patient comfort during HRM.Level of Evidence2 Laryngoscope, 2023
