abstract: Dress code: Emergency nurses at University College London Hospitals NHS Trust donned protective clothing last month as part of a simulated terrorist attack on the London underground. Forty 'casualties' were treated for poisoning with Sarin, the agent used on the Tokyo underground in 1995. They 'presented' with symptoms that included muscle spasm, eye irritation, a runny nose, faecal incontinence, vomiting and respiratory paralysis. A&E modern matron Debra Glastonbury said: 'We were able to get our first decontamination tent up in four minutes. And by the time the second one was up, we were in our suits and ready to receive casualties'.
