IntroductionIn this study, we retrospectively analysed healing times of ambulatory burn patients after silver-based dressings were introduced in late December 2005, and compared the results with those obtained before.Patients And MethodsData were collected in November-December 2005 and in January-February 2006. We excluded from the study: (i) admitted patients; (ii) patients with mixed superficial partial thickness and deep partial thickness burns; (iii) patients with full-thickness burns; and (iv) operated patients that came for follow-up. We recorded the age, sex, cause (flame vs scald), burn depth, dressings used and healing times.ResultsWe selected 347 patients corresponding to 455 burned areas (64.4% superficial and 35.6% deep; 47.7% treated in 2005 and 52.3% in 2006). During the years 2005 and 2006, there was an increase in the use of silver-based dressings (2005, 9.7%; 2006, 38.7%; chi-squared test, P < 0.001) and a decrease in the use of paraffin gauzes (2005, 66.4%; 2006, 40.3%; chi-squared test, P < 0.001). The healing time of overall burns and of superficial burns showed no significant differences between 2005 and 2006. However, in deep partial thickness burns, a significant reduction was present (2006, 19; 2005, 29 days; Student's t-test, P < 0.01). Among all dressings, paraffin gauzes had the shortest healing times in superficial burns (5 days); with silver-based dressings in deep burns, the healing times were nanocrystalline silver (16 days) and silver carboxymethylcellulose (21 days).ConclusionsResults of our retrospective study would suggest that paraffin gauzes are a valuable option in superficial burns, while silver-based dressings are preferable in deep burns.
