[Hemostatic disorders in anesthesiology and surgical intensive care].
Apart from straightforward haemorrhage, bleeding problems in anaesthesiology and intensive care are predominantly due to multifactorial haemostatic derangements caused by a depletion of procoagulant factors, inhibitors, and platelets. In certain settings, these events are complicated by an enhanced procoagulant and decreased fibrinolytic activity of the endothelium. This functional turnabout of the vasculature promotes disseminated intravascular coagulation (DIC). A rational therapeutic approach is based on estimates of the patient's losses and his volume of blood, adequate and repeated haemostatic monitoring, and an individually tailored substitution considering the critical levels of the informative parameters, i.e. the platelets, fibrinogen, Quick and aPTT, together with the haemostatic efficacy of the available preparations. Whenever possible, subclinical trends towards abnormal bleeding should be identified and countered by appropriate measures before an actual and potentially life-threatening haemostatic breakdown develops.
