Pre- and post-debridement wound cultures from patients undergoing serial surgical debridement of infected wounds were compared with outcomes 30 days postoperatively. One-hundred patients were enrolled; 35 were excluded for incomplete culture data. Sixty-five patients were evaluated for species counts, including Coagulase negative Staphylococcus (CoNS), and semiquantitative culture data for each debridement. The post-debridement cultures on the date of closure had no growth in 42 patients (64.6%) of which 6 dehisced (14.3%), and 36 remained closed; with no statistically significant difference in dehiscence rates (p=0.0664). Pre-debridement cultures from the 1st debridement of the 65 patients showed 8 patients had no growth, 29 grew 1 species, 19 grew 2 species, and 9 had 3-5 species. There was a reduction in the number of species and improvement of semiquantitative cultures with each subsequent debridement. The dehiscence rate for those who had 2 debridements (n=42) was 21.4% at 30 day follow-up and 21.7% in those who had 3 debridements (n=23). The number of debridements had no statistical significance on dehiscence rates. The presence of CoNS on the day of closure was a statistically significant risk for dehiscence within 30 days (p=0.0091) postoperatively. This data demonstrates: (1) positive post-debridement cultures (scant/rare, growth in enrichment broth) at the time of closure did not affect overall dehiscence rates (p=0.0664), (2) the number of species and semiquantitative culture results both improved with each subsequent debridement, (3) the number of surgical debridement did not influence postclosure dehiscence rates. (4) Positive cultures containing CoNS at the time of closure is a risk factor for dehiscence (p=0.0091) UR - https://dx.doi.org/10.1111/wrr.12509 ER -
