The evidence

A sedation-sparing adjunct for procedural sedation in children

Cravero JP, Roback MG

UpToDate cites Smileyscope as a nonpharmacologic, sedation-sparing adjunct for procedural sedation in children.

The Infusion Therapy Standards of Practice

Gorski LA, Hadaway L, Hagle ME, Broadhurst D, Clare S, Kleidon T, et al.

The Infusion Therapy Standards of Practice uniquely name Smileyscope for vascular access pain management. The only VR device cited in the Standards.

Virtual reality for paediatric needle procedural pain

Chan E, Hovenden M, Ramage E, Ling N, Pham JH, Rahim A, et al.

Two randomised controlled trials, which are the largest RCTs in VR for procedural pain/anxiety to date. Examined children aged 4 to 11 years old, undergoing venous access procedures in the emergency department and outpatient phlebotomy. Found significant reductions in pain, anxiety, caregiver distress and use of restraints.

VR for routine immunisations in needle-phobic children

Makhijani A, Jenkins N, Kaufman J, Hoq M, Priestley S, Elia S, et al.

Pilot study in needle-phobic children, including children with developmental disabilities, all of whom were scheduled for sedation. VR was able to avoid sedation for the majority of children, as well as improve patient/family satisfaction.

Of families would recommend

Using VR to assist coping in children undergoing clinical procedures

Samnakay S, Bell E, Evans D, Sommerfield D, Sommerfield A, Hauser N, et al.

Routine use across oncology, immunology, diabetes and general anaesthetic induction. High acceptability and improved coping reported across a range of busy clinical settings.

Acceptability and usability of Smileyscope during burn procedures

Storey K, Dimanopoulos TA, Plummer K, Kimble R, Xiang H, Griffin B.

Burn dressing changes, with perspectives from patients, carers and clinicians. Rated highly acceptable and usable by all three groups, with reduced pain, anxiety and improved epithelial tissue healing time.

Enhancing paediatric MRI preparation with virtual reality tools

Johnson BP, Garrick A, Lawrence KA, Papafotiou J, Young T, Chen J, et al.

Qualitative study of current MRI preparation practices and the role of VR. Families and staff reported reduced stress and improved stillness, supporting sedation avoidance. Smileyscope's synopsis cites more than 90% general-anaesthetic avoidance in children originally scheduled for MRI under anaesthesia.

3D VR versus 2D video during induction of anaesthesia

Samnakay S, von Ungern-Sternberg BS, Evans D, Sommerfield AC, Hauser ND, Bell E, et al.

Randomised controlled trial comparing 3D VR with 2D video during the induction of anaesthesia in children. 3D VR reduced pre-induction anxiety more than 2D video.

A tailored COVID-19 vaccination pathway for children aged 5 to 11

Gordon SF, Lam J, Vasquez JT, Cercone R, Tenneti N, Hart J, et al.

Paediatric COVID-19 vaccination pathway in Victoria, Australia, ages 5 to 11. Well received as part of a child-friendly vaccination pathway increasing patient comfort and compliance, especially over a series of vaccinations.

Clinical efficacy of VR for acute procedural pain management

Chan E, Foster S, Sambell R, Leong P.

Systematic review and meta-analysis of 20 randomised controlled trials of VR during short clinical procedures. VR consistently lowered peak pain during short procedures. Immersive VR outperformed 2D and non-immersive VR.

VR in paediatrics: effects on pain and anxiety

Tas FQ, van Eijk CAM, Staals LM, Legerstee JS, Dierckx B.

Updated systematic review and meta-analysis of VR for paediatric pain and anxiety. Confirms VR reduces paediatric pain and anxiety. The Smileyscope trials are rated among the strongest evidence in the field.

VR during intrauterine device procedures

Collins J, Alexiuk N, Burgess J, Singh GJ, Forbes K, Jayadeva P, Day S.

London-based health service evaluation of VR during IUD and subdermal implant insertion, with a companion report on clinician experience.
