The clinical Several studies have evaluated the association between hypothermia and abnormal bleeding through determination of coagulation times at different temperatures in human beings and animals. 24–26 Most of these studies have shown that hypothermia provokes dysfunction in coagulation, either intrinsically or extrinsically. 27 Hypothermia in temperatures below 33°C produces coagulopathy, which is functionally equivalent to states of moderate deficiency of coagulation factors (less than 50% of The effects of hypothermia on coagulation may represent a two-edged sword in patients with acute brain injury who are treated with therapeutic cooling.

On the one hand inhibition of coagulation can have positive effects, such as improvements in the m Background and Methods The development of a multifactorial coagulopathy after massive transfusion is a well-recognized clinical problem that is almost always accompanied by hypothermia.The purpose of this study was to investigate the isolated effect of alterations of temperature on the integrity of the coagulation cascade. Prothrombin times and partial thromboplastin times were each performed 2021-03-23 Considering the cellbased model of coagulation physiology, hypothermia predominantly prolongs the initiation phase, while acidosis prolongs the propagation phase of thrombin generation. 2011-05-01 2014-04-02 2012-04-06 Hypothermia and coagulation are complicated variables, potentially affected by injury severity, hemorrhage, and environment.

J Trauma 1997  Because restricting fluids is ill-advised, it is suggested that only a portion of perioperative coagulopathy could be mitigated by controlling core body temperature.5-  Dec 10, 2019 Because the kinetic tests of coagulation are performed at 37°C in the laboratory, a clinically evident coagulopathy may not be reflected by  Intraoperative hypothermia is associated with increased blood loss and We excluded patients with coagulation disorders or on anticoagulants before surgery .

In addition to the effects of hypothermia on platelet function and on the enzymes of the coagulation cascade, the activation of the fibrinolytic system induced by cold, either systemically or locally, can contribute to the increase of intraoperative bleeding. 29 Therefore, measures to prevent and correct hypothermia will also help to avoid coagulopathy.
