Therapeutic hypothermia complicated by spontaneous brain stem hemorrhage.

ABSTRACT

Hypothermia increases clotting time, which is known as hypothermic coagulopathy. However, prothrombin time and activated partial thromboplastin time prolongation associated with therapeutic hypothermia is usually mild and thus, hypothermic coagulopathy is not considered to cause clinically significant bleeding. On the other hand, PT and aPTT do not seem to reflect the severity of hypothermic coagulopathy. Serious bleeding complications of therapeutic hypothermia has not been reported previously. Herein, we introduce a case of spontaneous brain stem hemorrhage as a complication of therapeutic hypothermia-induced coagulopathy.
