An enzyme mixture containing bromelain (NexoBrid®) was found to be suitable for enzymatic debridement of burn wounds, as determined by the criteria of patient comfort and pain, selectivity, and efficiency. Nevertheless, daily experience showed that pretreatment of burn wounds with several other clinical agents may inhibit debridement efficiency. Therefore, the current study was performed to identify those agents and evaluate their debridement inhibition capabilities. ⋯ We recommend using polyhexanide-containing agents (Prontosan®) to rinse and presoak burn wounds. Pretreatment of burn wounds with agents containing silver and copper should be avoided. Experimentally, we found a partial inhibition of NexoBrid® activity at the distinct pH values of 3 and 11.

Burn injuries are generally considered to be among the most painful. However, there is little evidence to support this. It is also unknown if pain management in burn patients differs from patients with other sources of pain. ⋯ Adjusted for age and gender, burns had the smallest effect of all types of injuries on pain score except for open wounds, contusions, and crush injuries. Patients with fractures and dislocations were more likely to receive an opioid than burn patients after adjusting for pain severity. We conclude that pain severity due to burns is no greater than due to dislocations, fractures, and sprains/strains and that burn patients are less likely to receive opioid and nonopioid analgesics than fractures and dislocations.

Secondary burn necrosis is the expansion and deepening of the original burn injury several days after injury. Limiting the extent of secondary burn necrosis may improve outcomes. In this study, we examined the ability of the lipid mediator of inflammation-resolution resolvin D2 (RvD2) and chromatin-lysing enzyme (DNase) to reduce secondary burn necrosis. ⋯ We found that the interspace areas were preserved and had higher blood flow in the RvD2-treated group, while the burn areas expanded into the interspace areas, which were confluent by 7 days postburn, in the control-untreated group. We found a larger monocyte-to-neutrophil ratio in the RvD2-treated group compared with the DNase-treated and control groups (P < .05). Overall, RvD2 suppresses secondary necrosis and starts regeneration, highlighting the role of inflammation resolution as a potential therapeutic target in burn care.
