Hypothesis
A wound contaminated with sulfur mustard (HD) could be thoroughly decontaminated through excisional debridement despite delay in treatment.
Conclusion
Surgical decontamination is effective and safe if appropriate protective measures are taken, but there is significant occupational exposure risk to HD during these procedures.
Supporting Evidence
- Excisional debridement produced agent-free wound beds.
- A significant amount of HD vapor was detected above the surgical fields with each tool.
- All measured levels significantly exceeded established safety limits.
- Vesicating levels of unbound HD were extracted from excised tissue.
- There was no measured lateral spreading of HD beyond the surgical margins.
Takeaway
Doctors can clean wounds contaminated with dangerous chemicals, but they need to be very careful to protect themselves from getting hurt too.
Methodology
Weanling pigs were used to test different surgical tools for decontaminating wounds exposed to sulfur mustard.
Limitations
The study was limited to full-thickness skin wounds and did not explore other types of injuries.
Participant Demographics
Twelve female Yorkshire crossbred pigs, 11 to 14 kg.
