In a randomised trial by Ang, Lee, Gan, et al. (2001), patients with severe burns were emergency admissions into the specialist burns centre in Singapore requiring immediate treatment. Once admitted to the burns centre, only those patients with partial thickness thermal burns were eligible for the trial. Their consent was then sought and, once given, randomisation was accomplished by telephone to the statistical centre. Nevertheless, in certain cases, the attending medical team felt that the option of conventional therapy was more appropriate than the test therapy. For these patients, details of the clinical trial were not explained and conventional therapy commenced immediately.
