A number of potential complications are associated with cooling, including coagulopathy, arrhythmias, and hyperglycemia, particularly with an unintended drop below target temperature. 4
The likelihood of pneumonia and sepsis may also increase.
Hyper thermia is common after resuscitation, temperature elevation above normal can impair brain recovery. The etiology of fever after cardiac arrest may be related to activation of inflammatory cytokines in a pattern similar to that observed in sepsis .
