Recently, it has been reported that topical irrigations of liquid sevoflurane on the bed of painful wounds produce a rapid, intense, and lasting analgesic effect. In this paper, A cohort of 112 patients with painful pressure ulcers who were refractory to opioids (or who exhibited undesirable adverse events to them) was treated with topical sevoflurane as per local institutional policy. These patients were recruited from an intensive care unit for a period of 3 years. The main aim was to determine the effectiveness of topical sevoflurane in reducing the pain of PUs and reducing the ulcer area. Study findings are reported and discussed herein and suggest that sevoflurane is a viable and promising treatment option for PUs.
Vascular ulcers (VU) constitute a major cause of pain and disability, and significantly compromise quality of life. VU have a natural tendency to become chronic and in many cases exhibit anunsatisfactoryresponse to many of the standard therapeutic options.The case of a 73 year-old Caucasian female with severe pain and poorly-controlled pain (Visual Analogic Scale-VAS-of 8-9) due to three lower leg long-standing VUs is reported and discussed herein. The patient was treated with topical instillations of undiluted sevoflurane as per institutional off-label protocol (starting doses of 1mL/cm 2 twice a day, and up-titrated according to response to a maximum of 7 mL twice daily). The VAS score dropped to 0-1 shortly after initiation of therapy and remained stable throughout treatment up until the closure of the observations. Subsequently, opioid therapy was gradually tapered down and ultimately abandoned.Sevoflurane application resulted on adequate and sustained pain management of refractory VU, with no significant side effects. On account of its beneficial effectivity and safety profiles, topical sevoflurane emerges as an add-on alternative for the long-term management of VU, and potentially other painful conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
