Rewarming shock

Rewarming shock (also known as rewarming collapse) has been described as a drop in blood pressure following the warming of a person who is very cold.[1] The real cause of this rewarming shock is unknown.[1]

There was a theoretical concern that external rewarming rather than internal rewarming may increase the risk.[2] These concerns were partly believed to be due to afterdrop, a situation detected during laboratory experiments where there is a continued decrease in core temperature after rewarming has been started.[2] Recent studies have not supported these concerns, and problems are not found with active external rewarming.[2][3]
