Virtual reality for preoperative anxiety: what the research shows
Few moments in care are as anxious as the wait before surgery. Among the approaches studied to ease it, virtual reality already gathers consistent evidence from randomized trials — in adults and, especially, children.
The hours before an operation are, for many people, the most anxious part of the whole experience — the wait, the unknown, the operating room itself. That anxiety is not only unpleasant: in children especially it is linked to a more difficult recovery. Among the non-pharmacological approaches studied to ease it, virtual reality already has a consistent base of evidence from randomized trials. It is worth seeing what they show.
The mechanism: distraction and preparation
Virtual reality is used here in two distinct ways, and the difference matters:
- Distraction — immersing the patient in a calm, absorbing environment that pulls attention away from the wait and the clinical setting. Attention is finite; an engaging virtual world leaves less of it for anxious anticipation.
- Preparation (exposure) — walking the patient, beforehand, through what will actually happen: the rooms, the steps, the sounds. The unknown is a large part of preoperative fear, and making it familiar reduces it.
Reviews comparing the two suggest the distraction approach tends to show the stronger effect, though both are used.
What the randomized trials say
Here the evidence comes from controlled trials, not just observation:
- A meta-analysis of 10 randomized controlled trials with around 813 patients found preoperative anxiety significantly lower in the virtual-reality groups than in controls.
- Across a broader review of 29 studies, 25 (86%) showed statistically significant reductions in preoperative anxiety after a VR intervention, with a pooled effect size that is moderate and consistent.
- Reviews focused on pediatric surgical patients report the same significant benefit — important because anxiety before anesthesia is both common and consequential in children.
That virtual reality lowers preoperative anxiety is supported by multiple meta-analyses of randomized trials — in adults and children alike — which is a stronger footing than single studies provide.
The limits it is honest to mention
- Effects are measured around the perioperative window; this is about easing a specific, time-limited anxiety, not treating an anxiety disorder.
- Studies vary in headset, content, and whether they distract or prepare, which widens the range of reported effects.
- It is a complement to good clinical communication and care, not a replacement for either.
Important note: virtual reality for preoperative anxiety is a complementary approach used under clinical supervision. It does not replace anesthetic assessment, premedication where indicated, or the reassurance of the surgical team. This article is informational and does not constitute clinical advice.
The role of RVer
RVer is an immersive virtual reality therapy system designed for healthcare environments and certified as a Class I Medical Device by Infarmed, in compliance with the European regulation MDR 2017/745. It is built to deliver calm immersion that staff can start in seconds in a pre-op bay or day-surgery unit — simple to use, hygienic between patients, and with no collection of patient clinical data.
When the wait before surgery is unavoidable but the anxiety around it is not fixed, immersive virtual reality offers a low-risk, drug-free way to make it calmer — always as a complement to attentive clinical care.
