Leukopenia in non-septic burn patients receiving topical 1% silver sulfadiazine cream therapy: a survey

The cause of early postburn leukopenia (EPBL) is unknown. The evidence suggests that treating burn wounds with 1% silver sulfadiazine cream (SSD) is contributory, but that other factors exist, possibly including burn stress. Differences of opinion exist as to whether SSD applications to the wounds of non-septic burn patients should be discontinued if EPBL develops. A survey of opinion in 101 North American burn treatment facilities and a review of the literature show a strengthening of the perception that EPBL, whether caused by SSD or not, holds little risk for the burn patient. The majority of burn patients are now being assigned to treatment strategies in which the onset of EPBL requires discontinuance of SSD only at WBC counts lower than 2,000/cu mm or not at all. This is significantly lower (p less than .02) than the mean of the values recorded in the literature. There is now substantial experience with continuing the SSD therapy in this setting regardless of the WBC count. No complications are reported therefrom.
