The present study assesses the efficacy and safety of topical sevoflurane in chronic venous ulcers and its impact on analgesia and healing. This retrospective study included 30 patients older than 65 years with painful refractory chronic venous ulcers. Patients were treated with topical sevoflurane prior to the usual ulcer cleaning every 2 days for a period of 1 month. Treatment was initiated with a saline solution, followed by direct irrigation of 1 ml of liquid sevoflurane over the wound size, which was measured as cm2 . Sevoflurane had a fast, intense and long-lasting analgesic effect. Latency time ranged from 2 to 7 minutes (3·9 ± 1·5 minutes), and duration varied from 8 to 18 hours (12 ± 2·9). The mean ulcer size was 8·4 ± 9·7 cm2 . There was a progressive decrease in size in all patients, with a mean size of 4·2 ± 5·4 cm2 at the end of the study. There were no adverse systemic effects. Local adverse effects were mild and transient, including pruritus, erythema and heat. Topical sevoflurane is a new, efficient and safe therapeutic alternative in painful chronic venous ulcers, refractory to usual analgesic treatment. It can improve the ulcer-healing process that shortens the cicatrisation period.
