Filter by:In a single-blind, crossover, randomized, controlled trial with 40 participants we aim to demonstrate superior anaesthetic efficacy of lidocaine-23%-tetracaine-7% (IMP2) gel over EMLA 5% cream (IMP1) at comparable safety in sharp wound debridement of chronic leg ulcers. This is a monocentric investigator initiated trial conducted in the University Hospital Zurich. In this longitudinal trial, participants receive a sequence of different treatments (treatments on different days) and therefore are randomly assigned to one of two treatment sequences. One-half of participants will first receive IMP1 (first treatment visit, randomized) and then IMP2 (second treatment visit, crossover); the other half of participants the reverse sequence (first treatment visit: IMP2, second treatment visit: IMP1). Primary Objective: We want to show that IMP 2 (lidocaine-23%-tetracaine-7% gel) is more effective in pain reduction than IMP 1 (EMLA® 5% cream) in sharp wound debridement.
Venous ulcers are defined by the presence of open lesions which represent the final stage of chronic venous disease or post-thrombotic syndrome. The risk factors for the development of venous ulcers include age, obesity, female sex, trauma, immobility, factor V mutation, thrombosis, venous agenesis. Recommendation by the current guidelines includes compression and advanced dressing. However, in several cases, they fail to change patients' outcome. The aim of this study is to identify an alternative therapy to treat venous trophic lesions not responding to traditional therapeutic approaches using extracellular vesicles obtained from autologous serum.
