Pain, Quality of Life, and Functional Capacity With Topical Sevoflurane Application for Chronic Venous Ulcers: A Retrospective Clinical Study

Initial VAS was 8.8 ± 1.3 points and at the twelfth cleaning VAS was 0.8 ± 1 points (p = .001). Latency time ranged between 2 and 7 m and duration ranged between 8 and 18 h. It improved quality of life (83 ± 14 points before treatment vs. 50 ± 14 at the twelfth cleaning) and functional capacity (82 ± 13.3 before treatment vs. 91 ± 11.6 points at the twelfth cleaning) (p = .001). The safety profile was favourable with mild and self limited local cutaneous adverse effects, including pruritus, erythema, and heat. No systemic toxicity was detected. Topical sevoflurane may be a therapeutic alternative for painful CVU with a fast, intense, and long-lasting analgesic effect.
