WebThe intrinsic pathway can be activated by surface contact, when damage to the vascular endothelium leads to exposure of clotting factors to negatively charged subendothelial surfaces, mediated by the molecule Kallikrein. Within blood vessels, thrombin generated from previous activation of the extrinsic pathway also activates the intrinsic pathway. WebThere was no evidence supporting the assumption that TTM at 33°C was associated with impaired hemostasis or increased the frequency of adverse bleeding and thrombotic events compared to TTM at 36°C. We found that TTM at either temperature can safely be applied in the postresuscitation phase after ac …
