Wound debridement times of first surgical debridement. The debridement times (skin to skin) were recorded in surgical debridement procedures that were randomised to either conventional scalpels and pulsed lavage or VERSAJET as described in Materials and Methods. The data from wounds were subsequently analysed in accordance with whether or not they contained black necrotic tissue. There was marginal statistical evidence (P= 0·098) that the difference between the treatment groups in wound debridement time depended on the area of black necrotic tissue.
