| Popis: | BACKGROUND: Some authors claim that the clinical methods often employed to assess chronic venous leg ulcers (CVLU) are based on subjective interpretation. The treatments based on a subjective characterization could become a trial-and-error therapy, resulting in longer evolutions and high recurrence rates. PURPOSE: The aim of this work was to compare numeric parameters from acute and chronic venous leg ulcers to identify potential objective nonhealing parameters. METHODS: The study was performed with hospital outpatients from 2016 to 2019. Cohorts were established according to the ulcer evolution time. Data collected related to ulcer characteristics included exudate pH, lactate and glucose concentrations, temperatures, microbiology findings, and imaging study results. RESULTS: Approximately 83% of the examined ulcers were chronic. Seventy-one percent of CVLUs and 59% of the acute ulcers had a pH ≥8. A high variability was found for the concentration of glucose and lactate in exudates of both acute and chronic ulcers. Variations of temperatures of normal skin (ΔT1) and periulcer zone (ΔT2) in reference to the wound bed temperature with values above 1 could indicate the presence of an inflammatory process and be used as a new potential marker of inflammation. All the acute ulcers and 88% of CVLUs showed |
