Abstract
The general anesthetic sevoflurane is being repurposed as a topical analgesic for painful chronic wounds. This study was aimed to compare the analgesic effectiveness and safety of systemic analgesics alone or plus at-home topical sevoflurane for the management of patients with painful nonrevascularizable leg ulcers who were referred to a Pain Clinic by their attending vascular surgeons. We reviewed charts of patients treated in a single Pain Clinic with analgesic Standard of Care either alone (group SoC) or plus at-home topical sevoflurane (group SoC + Sevo), according to safety criteria. The area under the curve of pain over a year (AUC-Pain) was the primary outcome for analgesic effectiveness. Opioids were converted into Oral Morphine Milligram Equivalents. Groups SoC (n = 26) and SoC + Sevo (n = 38) were similar in baseline characteristics. Compared to SoC, median values [interquartile range] of area under the curve of pain for one-year follow-up were markedly lower for SoC + Sevo (54 [35-65] vs. 15 [11-23]; p < 0.000001, U Mann-Whitney test). Oral Morphine Milligram Equivalents were similar at baseline (SoC: 78.5 [22.5-135] vs. SoC + Sevo: 101.3 [30-160]; p = 0.753), but significantly lower for SoC + Sevo at three (120 [22.5-202.5] vs. 30 [0-80]; p = 0.005), six (120 [11.3-160] vs. 20 [0-67.5]; p = 0.004), nine (114.4 [0-154] vs. 0 [0-37]; p = 0.018), and 12 months (114.4 [0-154] vs. 0 [0-20]; p = 0.001). Multiple linear regression analysis revealed the addition of sevoflurane to be the most likely variable to explain this difference in outcome (ß:-33.408; p < 0.000001). Nine patients (24%) in SoC + Sevo had adverse effects attributed to sevoflurane, but only one patient needed to stop using sevoflurane due severe dermatitis. In conclusion, the addition of topical sevoflurane to the analgesic standard of care in patients with painful nonrevascularizable leg ulcers was a well-tolerated therapy that significantly improved pain control and allowed for a significant reduction in opioid consumption.

Abstract
Sevoflurane is being repurposed as a topical analgesic for painful wounds. Providing pre-charged sevoflurane syringes to irrigate wounds implies a potential risk of accidental intravenous injections. We assessed the potential of two concentrations (33% and 50% v/v) of three anesthetics, isoflurane, desflurane and sevoflurane, to produce hemolysis in vitro. Spectrophotometric absorbance was read at 576 nm. For both concentrations, the percentage of hemolysis (mean ± SD) was higher for isoflurane (29.7 ± 3.4% and 39.5 ± 5.3%), mild for desflurane (8.0 ± 0.5% and 6.5 ± 0.9%) and negligible for sevoflurane (0.7 ± 0.0% and 0.6 ± 0.1%), respectively. In conclusion, in contrast to isoflurane and desflurane, sevoflurane did not display hemolytic potential in vitro. However, the use of syringes preloaded with sevoflurane may still be problematic if it increases the possibility of inadvertent intravenous administration through increased risk of gas embolism and severe central nervous system depression.

Abstract
Objectives The general anesthetic sevoflurane is being repurposed as a topical analgesic for painful chronic wounds. We conducted a Bayesian cost-effectiveness analysis (CEA) comparing the addition of domiciliary topical sevoflurane to conventional analgesics (SEVOFLURANE, n = 38) versus conventional analgesics alone (CONVENTIONAL, n = 26) for the treatment of nonrevascularizable painful leg ulcers in an outpatient Pain Clinic of a Spanish tertiary hospital. Methods We used real-world data collected from charts to conduct this CEA from a public healthcare perspective and with a one-year time horizon. Costs of analgesics, visits and admissions were considered, expressed in €2016. Analgesic effectiveness was measured with SPID (Sum of Pain Intensity Difference). A Bayesian regression model was constructed, including “treatment” and baseline characteristics for patients (“arterial hypertension”) and ulcers (“duration”, “number”, “depth”, “pain”) as covariates. The findings were summarized as a cost-effectiveness plane and a cost-effectiveness acceptability curve. One-way sensitivity analyses, a re-analysis excluding those patients who died or suffered from leg amputation, and an extreme scenario analysis were conducted to reduce uncertainty. Results Compared to CONVENTIONAL, SEVOFLURANE was associated with a 46% reduction in costs, and the mean incremental effectiveness (28.15±3.70 effectiveness units) was favorable to SEVOFLURANE. The estimated probability for SEVOFLURANE being dominant was 99%. The regression model showed that costs were barely influenced by any covariate, whereas effectiveness was noticeably influenced by “treatment”. All sensitivity analyses showed the robustness of the model, even in the extreme scenario analysis against SEVOFLURANE. Conclusions SEVOFLURANE was dominant over CONVENTIONAL as it was less expensive and much more effective.

Topical Sevoflurane: A Novel Treatment for Chronic Pain Caused by Venous Stasis Ulcers. Anesth Pain Med 2021; 11:e112832. [PMID: 34221949 PMCID: PMC8241821 DOI: 10.5812/aapm.112832] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Revised: 02/14/2021] [Accepted: 02/14/2021] [Indexed: 11/16/2022] Open
Abstract
In the US, an estimated 1 - 2% of chronic venous insufficiency (CVI) patients (of 6 - 7 million nationwide) develop at least one venous stasis ulcer (VSU) during their illness. Of these, approximately 40% develop subsequent ulcers, making VSU prognostically poor. Current management of VSU is costly, with poor prognosis, high recurrence rate, inadequate pain management, and significantly reduced quality of life (QoL). Topical volatile anesthetic agents, such as sevoflurane, offer improved pain relief and symptom control in patients suffering from chronic VSU. The immediate impact of topical sevoflurane in reducing pain associated with ulcer bed debridement has several implications in improving the quality of life in patients with CVI induced ulcers and in the prognosis and healing of the ulcers. This review summarizes a topical formulation of a volatile anesthetic and its implications for the management of VSUs.

Abstract
Background: The aim of the study was to analyze the dynamics of pain severity and its predictors in a group of patients with chronic venous leg ulcers. Methods: A 12-week longitudinal study included 754 patients with chronic venous leg ulcers. Subjective severity of pain was measured at weekly intervals with an 11-point visual analogue scale (VAS). Results: A significant decrease in VAS scores has been observed throughout the entire analyzed period. Higher severity of pain during follow-up was independently predicted by the presence of pus and/or unpleasant smell from the ulceration during the first visit, as well as by the occurrence of posterior and/or circumferential ulcers. The presence of ulcer redness during the first visit was associated with lesser pain severity; also, a significant interaction effect between the ulceration redness and warmth was observed. Conclusions: Implementation of complex holistic care may contribute to a substantial decrease in the occurrence and severity of pain in a patient with venous leg ulcers. Pain control seems to depend primarily on clinical parameters and topography of venous ulcers. The predictors of pain severity identified in this study might be considered during the planning of tailored care for patients with venous leg ulcers.

Abstract
Proper symptom management to improve quality of dying is mandatory in palliative care patients. Home-based control of pain caused by leg ulcers is challenging, especially when the pain is severe and refractory to conventional analgesics, the patient is intolerant to opioids and refuses invasive measures. This was the case for an 87-year-old woman under oncological palliative care who suffered from a leg ulcer causing refractory pain, which produced suicidal ideation. Leg amputation was indicated, but she had signed a living will refusing any invasive measures. After obtaining written informed consent, sevoflurane was applied topically on the ulcer, which resulted in a rapid and long-lasting reduction of pain. Daily self-administration of sevoflurane successfully controlled the wound pain and the patient abandoned her suicidal ideation, the wound healed 35 days later, and her quality of dying improved remarkably. Topical sevoflurane deserves further research on ulcers of vascular and also neoplastic aetiology.

Abstract
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.

Abstract
OBJECTIVE Analgesic topical options to perform wound debridement are scarce. The purpose of this study was to communicate our experience using topical sevoflurane as analgesic for wound debridement. METHODS After approval by our institutional review board, medical records were reviewed for those patients who had previously accepted to be treated with off-label topical sevoflurane (1 mL/cm2) as an analgesic for sharp debridement of painful wounds, because it was previously approved by our institutional Pharmacy Regulatory Commission and Medical Management. According to this protocol, pain scores were measured by using a numerical rating scale (from 0 to 10 points) over a 10-hour period. Wound debridement was performed following routine procedures. RESULTS Medical records from 152 patients were reviewed. Baseline pain was severe (median, 7 points). After topical sevoflurane application, the analgesic effect was rapid (median pain score of 2 points at 5 minutes), and full debridement was feasible in most wounds (93%). The initial intense analgesic effect lasted for 30 minutes and then it subsided gradually over time to nearly reach baseline values after 10 hours. The patients estimated that the analgesic effect lasted several hours (median, 9 hours), and their overall satisfaction was high (median of 8 points on a scale ranging from 0 to 10). Fifty-two patients (34%) experienced itching. CONCLUSIONS Topical application of sevoflurane to painful wounds produced a rapid, robust, and long-lasting analgesic effect, which allowed for a high degree of wound debridement.

Abstract
ABSTRACT Objective: To evaluate the quality of life of people with chronic wounds and to compare this index with clinical parameters. Method: A cross-sectional study conducted between July 2014 and February 2015, evaluating people with chronic wounds in outpatient care during a nursing consultation, in the city of Guarapuava, Paraná. Quality of life was assessed by the Quality of Life Index - wounds version. Data were analyzed using the Mann Whitney test and T-test. Results: 53 people participated. The mean quality of life score was 22.65±3.08. The most significant scores in the analyzes were the family domain (27.71±2.94) with the highest mean score, and the health domain (18.91±4.58) had the lowest. Pain in walking (p=0.031) and using pain medication (p=0.002) presented a significant relation with overall score. There was a significant difference between the groups for the items pain at rest (p=0.022), pain in moving (p=0.006), using pain medication (p<0.001) and presence of infection (p=0.004), in the rest item (p=0.015) in the socioeconomic domain, and type of wound (p=0.05) and rest (p=0.041) in the psychological domain. Conclusion: The overall Quality of Life Index and by domains was classified as good and very good, where the family domain was better evaluated to the deriment of the health domain due to the clinical parameter of pain.
