The above article from Anaesthesia, published online on 16 April 2010 in Wiley Online Library (wileyonlinelibrary.com) and in Volume 65, No. 6, pp. 595–600, has been retracted by agreement between the journal Editor-in-Chief, Steve Yentis, the authors and John Wiley & Sons Ltd. This article is being retracted because it did not refer to a previous paper arising from the same work on the same patients 1, and different power calculations and primary outcomes were presented in these papers as if they were separate studies. In addition, we are informed by the Research Ethics Committee Chairman that the Committee was not informed that the protocol and sample size had been changed after approval, nor that the study had finished, both of which were required by the Committee.
