Assessment of patient experience with virtual reality during regional nerve block at an ambulatory surgery center

Joseph Hodapp M.D., Cora Steindl NP, Cynthia Khoo M.D., PhD

Introduction:

  • Reduce perioperative anxiety in pediatric patients,  pain during wound care in burn patients, and cancer-related symptoms during chemotherapy infusions

  • Decrease the use of analgesics and sedatives during adductor canal catheter placement all while also being associated with improvement in procedure-related pain

  • Intraoperative use during upper limb surgery under regional anesthesia with increase in patient satisfaction and decrease in anxiety and intraoperative hemodynamic changes

  • Aim: Assess if VR is feasible to implement in our outpatient surgery regional block patients and determine the barriers from a patient perspective.

Study Design

  • IRB approval 63889 for prospective, non-randomized, single-center trial

  • Location: Redwood City Outpatient Surgical Center

  • Inclusion criteria: Age 18+, receiving preoperative regional block

  • Large language model  to  identify themes from qualitative responses

Results & Discussion

  • According to the Patients

    • With VR: improved satisfaction and decreased pain during block

    • Key pros to VR: soothing, distracting

    • Key cons to VR: fogging with mask, uncertainty, lack of awareness 

  • Limitations: small sample, not randomized, 45% attrition rate 

  • Areas for further research:

    • Addressing the negative themes:

      • Trialing multiple size headsets 

      • Trialing different virtual reality scenes

    • Development of educational materials for patients and staff to facilitate utilization of virtual reality in the perioperative setting.
