virtual reality and coping with procedural pain in burn patients

Conditions: Burns; Virtual Reality; Anxiety; Pain

Summary: the main aim of the project is to reduce the feeling of procedural pain (when changing bandages) in burn patients through a developed and pilot-verified application for virtual reality (hereinafter vr). the first study on this topic was conducted in the us on two pediatric patients. in addition to pharmacological pain therapy, there are a number of non-pharmacological options (eg, relaxation techniques) that are based on distracting attention from the feeling of pain. vr appears to be the most promising of these options and, in addition to distraction, it also reduces anxiety and depressive symptoms and enhances patient cooperation. the studies also agree on the beneficial role of immersivity; a sense of immersion in vr.

the project was preceded by a pilot verification to select an appropriate approach for implementing the research design, including the development of a new vr application that took into account current technological advancements in this field. as part of the pilot verification, a custom application was created based on experiences with existing vr applications designed for therapeutic purposes for burn trauma patients in collaboration with space s.r.o. patients meeting the selection criteria (e.g., extent of burns, consent to participate in the study, and other relevant factors) were included in the study after the second dressing change in the dressing room. it was during these dressing changes that procedural pain occurred, first during the removal of old dressings and then during the removal of necrotic tissue and the application of new dressings. each of these painful procedures was divided into two parts: 1) removal of old dressings; 2) removal of necrotic tissue and application of new dressings. in the study, pain sensation was repeatedly measured using the nprs (numeric pain rating scale) and bspas (burns specific pain anxiety scale) for both parts in at least 30 patients. before each dressing change, it was randomly determined whether the vr would be used during the first part (removal of old dressings) or only during the second part (removal of necrotic tissue and application of new dressings). additionally, the part involving vr was further assessed using a short immersion inventory, the igroup presence questionnaire (ipq). in the end, it was possible to evaluate the effect of vr on pain management during dressing changes in patients with burn trauma. the investigators will continue to measure several variables. the feeling of nausea will be assessed in a virtual environment on an ordinal scale from 0, indicating no nausea, to 10, indicating the worst imaginable nausea. age will be recorded and categorized into six ordinal groups ranging from 18 to 70 years and older. the type of medications participants are currently taking will be recorded, categorized into six levels, including options ranging from none to five types of medications, such as strong opioids and analgesics. the total body surface area (tbsa) burned will be measured, with categories ranging from 0.4% to 45% or more. additionally, the investigators will assess how the burn was caused, with categories including electro trauma, scalding, chemical trauma, frostbite, and flame burns. they will also evaluate participants\&#39; gaming and vr experience, determining whether participants consider themselves gamers, play games regularly, or have personal experience with virtual reality. these measurements aim to provide a detailed understanding of the participants´ conditions and their responses during the study.

Eligibility criteria:
inclusion criteria: * sustained a thermal injury covering a total body surface area of 0.4% or more * actively receiving therapy for the injury * proficient in the czech language exclusion criteria: * presence of facial burns * acute psychotic illness * neurodegenerative diseases * other neurological conditions associated with potential cognitive impairment
