Es stimmt auch nach aktuellem Stand der Wissenschaft, dass frisch Gerettete gerne noch beim Erwärmen wegsterben - allerdings wird dieses Risiko durch "external warming" im Vergleich verschiedener Methoden nach neueren Studien angeblich nicht erhöht, wozu ich nicht up-to-date war.
"[...] The UK National Health Service advises against putting a person in a hot bath, massaging their arms and legs, using a heating pad, or giving them alcohol. These measures can cause a rapid fall in blood pressure and potential cardiac arrest."
"[...] When severe hypothermia has led to cardiac arrest, effective extracorporeal warming results in survival with normal mental function about
50% of the time." [Hervorhebung von mir]
"
Rewarming shock (or
rewarming collapse) is a sudden drop in blood pressure in combination with a low cardiac output which may occur during active treatment of a severely hypothermic person.[70][71] 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."

Zum Thema späterer Wiederbelebung steht dort aber auch:
"Children who have near-drowning accidents in water near 0 °C (32 °F) can
occasionally be revived, even over an hour after losing consciousness. [...] While survival is possible,
mortality from severe or profound hypothermia
remains high despite optimal treatment." [Hervorhebungen von mir]
