Virtual reality distraction during uterovaginal brachytherapy applicators' removal: A pilot comparative study

Area of Science:

• Oncology
• Radiotherapy
• Pain Management

Background:

• Cervical brachytherapy requires applicator removal, which can cause patient anxiety and pain.
• Current methods like nitrous oxide (N₂O) conscious sedation have limitations.

Purpose of the Study:

• To evaluate virtual reality (VR) distraction as an alternative to N₂O for reducing anxiety and pain during uterovaginal brachytherapy applicator removal.
• To assess the feasibility and patient experience with VR during this procedure.

Main Methods:

• A prospective study involving 35 patients undergoing cervical brachytherapy.
• Patients were randomized to receive either N₂O conscious sedation or VR distraction.
• Anxiety and pain were measured using STAI-E and Visual Analogical Scales (VAS).

Main Results:

• The VR group showed comparable or lower anxiety and pain scores compared to the N₂O group.
• While preparation time was longer for VR, the removal duration was similar.
• Four patients in the VR group reported mild side effects like nausea or dizziness.

Conclusions:

• Virtual reality distraction is a feasible and acceptable alternative to N₂O for managing pain and anxiety during brachytherapy applicator removal.
• Further randomized trials are necessary to confirm VR's efficacy and identify optimal patient candidates.
