Background/Objectives: Pain management during minor surgical procedures in wound care across various etiologies is often underestimated in daily clinical practice. Pharmacotherapy remains the most effective and efficient method for pain reduction. However, growing concerns regarding the side effects of traditional analgesics and distressing psychosomatic experiences highlight the need for innovative non-pharmacological pain management strategies. The use of virtual reality (VR) has been suggested as a potential method to alleviate pain during medical procedures. The aim of this study was to assess the feasibility of virtual reality as a non-pharmacological approach to pain reduction during the debridement and dressing of hard-to-heal vascular wounds. Methods: This prospective observational study included a cohort of 100 patients who were consulted and treated at a specialized wound care clinic in the Podkarpacie region, Poland. Participant selection was based on predefined inclusion criteria. Patients were assigned to two groups: Group A, in which VR goggles were used, and Group B, in which standard care without VR was provided. All wounds were pre-treated with Lignocaine 2% gel for approximately 3–5 min before tissue debridement. Pain intensity was measured before the procedure, during the procedure, and 10 min after completion. A structured research questionnaire was used for data collection, consisting of two parts: sociodemographic data, functional assessment, wound characteristics, clinical scales, and the Numeric Rating Scale (NRS) for pain assessment before, during, and after the procedure. Results: A total of 100 participants voluntarily took part in the study, of whom 49.0% (n = 49) were male and 51.0% (n = 51) were female. The age of participants ranged from 43 to 89 years, with a mean age of 68.02 ± 10.0 years. A statistically significant difference in pain perception was observed between the pre-procedure and intra-procedure phases of wound debridement. The average pain increase in the Group with VR was lower than in the Group without VR (p = 0.006, effect size = 0.32). Conclusion: Pain occurrence and intensity during wound debridement are common challenges in clinical practice. The visual perception of a bleeding and treated wound may contribute to the psychogenic pain component. Virtual reality may serve as a simple adjunctive method to medical procedures by diverting attention away from surgical interventions. Further research, including psychological aspects of non-pharmacological pain management, is necessary in the context of wound care prevention and treatment.

Background: Critical illness leads to profound metabolic, neuroendocrine and immune disorders that affect the prognosis of patients treated in intensive care units (ICUs). The ketogenic diet, a high-fat and low-carbohydrate eating model, is gaining increasing importance as a potential metabolic intervention in the ICU. Preliminary data suggest that the ketogenic diet (KD) may support the control of seizures in a super-refractive epileptic state (SRSE), stabilize glycemia, reduce insulin demand, and modulate the immune response in sepsis. The aim of this review was to present a synthetic presentation of the current state of knowledge regarding use of the KD in intensive care patients. Methods: The review was carried out in accordance with the guidelines of the Joanna Briggs Institute and PRISMA-ScR. PubMed, Scopus, EBSCO, Web of Science, Google Scholar and Cochrane Library databases were searched (10–19 April 2026) using the Population–Concept–Context model. Full-text observational studies, randomized trials and reviews of the use of KDs in ICU patients were included. Data extraction was performed independently by two reviewers. Results: Of the 42 publications identified, seven studies were included in the analysis. The KD was feasible and safe in both critically ill adults and children. In SRSE, most patients achieved stable ketosis within a few days, which often allowed for reduction or discontinuation of anesthetics. In sepsis, the KD led to glycemic stabilization, reduced insulin demand and reduced immune deregulation; in one study, “after day 4, none of the patients in the KD group required insulin treatment.” The KD also showed beneficial effects on cellular bioenergetics and mitochondrial function. The safety profile was acceptable and adverse reactions were manageable with appropriate monitoring. Conclusions: The KD represents a promising, non-pharmacological metabolic intervention in intensive care, particularly in the treatment of SRSE and in the stabilization of glucose metabolism in sepsis and other critical conditions. Despite the growing number of positive clinical observations, the available evidence remains limited due to small samples, heterogeneous protocols, and a lack of randomized trials. Further, well-designed prospective studies are needed to determine optimal KD implementation protocols and identify the patient populations that benefit most.
