Background and Aims Immersive Virtual Reality(VR) simulator used in anaesthesia for relaxing images, videos and sounds, to engage the patient from the distraction of surgery.3-D environment puts patient in hypnotic state and reduces Phobias and stress levels. Virtual reality distraction decreases routine intravenous sedation and procedure-related pain during preoperative blocks(1).’VR for Peripheral Regional Anaesthesia (VR-PERLA Study)’, demonstrated benefit in improved patient satisfaction levels . Aim – 1. Primary outcomes are to study patient self reported satisfaction levels with and without VR . 2.Secondary outcomes were patient anxiety levels monitored with or without VR and reduced sedation requirements.

Methods 1. 15 Patients for elective orthopaedic surgery were consented for VR under Loco-regional anaesthesia ( Adductor canal , axillary , interscalene blocks). VR initiated on arrival to Anaesthesia room. Comparison were made with 15 similar patients undergoing similar procedures without VR. 2. Self-reporting patient‘s satisfaction on five-point Likert scale ((1 = very dissatisfied, 2 = dissatisfied, 3 = neutral, 4 = satisfied, and 5 = very satisfied.

1. Modified Observer’s Assessment of Alertness and Sedation (MOAA/S) scale 6-point scale .

Results 2. MOAA/S scales were 5 in all patients having VR, with appropriate response to verbal stimuli . 3.Likert scale- all VR patients were satisfied.

Conclusions 1. Both Primary and secondary outcomes met through VR use. 2. Onset of peripheral nerve block, administration of systemic analgesics, Pre-op anxiety & analgesic history pre-op were significant determinant factors for patients’ level of satisfaction. 3.VR reduces anxiety & sedation requirement levels in Loco-Regional anaesthesia and improves satisfaction with more Haemodynamic stability.
