Abstract
AbstractIntroductionHypothermia may be encountered at some time in most parts of Australasia. There is a need to evaluate the merits of the various practical rewarming therapies available.MethodAn electronic and manual search of databases to identify randomised trials published between 1966 and 1996 inclusive which evaluated rewarming therapies in hypothermia.ResultsThere is a paucity of randomised trials on this subject and many of the rewarming therapies recommended in authoritative texts and reviews have never been evaluated in randomised clinical trials. In published trials core afterdrop is typically <0.5 C and is least with active core rewarming. Passive rewarming alone may be expected to raise core temperature by 0.75 C/hr and the addition of inhalation and/or forced air rewarming can be expected to at least double this.ConclusionsThe choice of rewarming therapy may be largely one of practicality and availability. Future rewarming research should focus on clinical outcomes in patients with moderate to severe hypothermia.
