Clinical Efficacy, Safety, and Feasibility of Using Video Glasses during Interventional Radiologic Procedures: A Randomized Trial

Purpose: To evaluate the clinical efficacy, safety, and feasibility of implementing video glasses in a variety of interventional radiologic (IR) procedures.

Materials and methods: Between August 2012 and August 2013, 83 patients undergoing outpatient IR procedures were randomized to a control group (n = 44) or an experimental group outfitted with video glasses (n = 39). State-Trait Anxiety Inventory (STAI) scores, sedation and analgesia doses, mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), pain scores, and procedure times were obtained. Complications and adverse events related to the use of video glasses were recorded. Postprocedural staff surveys and patient satisfaction surveys were completed.

Results: Women had greater preprocedural anxiety than men (P = .0056), and patients undergoing vascular interventions had greater preprocedural anxiety than those undergoing nonvascular interventions (P = .0396). When assessed after the procedure, patients who wore video glasses had significantly reduced levels of anxiety (-7.7 vs -4.4, respectively; P = .0335) and average MAP (-6.3 vs 2.1, respectively; P = .0486) compared with control patients. There was no significant difference in amount of sedation and analgesia, HR, RR, pain score, or procedure time between groups. No significant adverse events related to the use of video glasses were observed. Postprocedural surveys showed that video glasses were not distracting and did not interfere or pose a safety issue during procedures. Patients enjoyed using the video glasses and would use them again for a future procedure.

Conclusions: Video glasses can be safely implemented during IR procedures to reduce anxiety and improve a patient's overall experience.
