Virtual Reality for the Management of Pain and Anxiety in Patients Undergoing Implantation of Pacemaker or Implantable Cardioverter Defibrillator: A Randomized Study.

Background: The Virtual Reality Headset (VRH) is a device aiming at improving patient's comfort by reducing pain and anxiety during medical interventions. Its interest during cardiac implantable electronic devices (CIED) implant procedures has not been studied.

Methods: We randomized consecutive patients admitted for pacemaker or Implantable Cardioverter Defibrillator (ICD) at our center to either standard analgesia care (STD-Group), or to VRH (VRH-Group). Patients in the STD-Group received intra-venous paracetamol (1 g) 60 min before the procedure, and local anesthesia was performed with lidocaine. For patients of the VRH-Group, VRH was used on top of standard care. We monitored patients' pain and anxiety using numeric rating scales (from 0 to 10) at the time of sub-cutaneous pocket creation, and during deep axillary vein puncture. Patient comfort during the procedure was assessed using a detailed questionnaire. Morphine consumption was also assessed.

Results: We randomized 61 patients to STD-Group (n = 31) or VRH-Group (n = 30). Pain and anxiety were lower in the VRH-Group during deep venous puncture (3.0 ± 2.0 vs. 4.8 ± 2.2, p = 0.002 and 2.4 ± 2.2 vs. 4.1 ± 2.4, p = 0.006) but not during pocket creation (p = 0.58 and p = 0.5). Morphine consumption was lower in the VRH-Group (1.6 ± 0.7 vs. 2.1 ± 1.1 mg; p = 0.041). Patients' overall comfort during procedure was similar in both groups.

Conclusion: VRH use improved pain and anxiety control during deep venous puncture compared to standard analgesia care, and allowed morphine consumption reduction. However, pain and anxiety were similar at the time of sub-cutaneous pocket creation.
