Management of Hemostasis and Coagulopathies for Surgical and Critically Ill Patients: An Evidence-Based Approach offers a concise guide to a sub-specialty of transfusion medicine from the clinical laboratory perspective. It focuses on the clinical tests that may be done during preoperative assessment, intraoperative, and postoperative assessment and management of surgical or critically ill patients. Management of hemostasis and coagulopathies is approached from an evidence-based perspective-the coagulation status of a patient according to the laboratory test results. Algorithms and decision-support software, designed by the authors, guide clinicians with an additional tool to base transfusion dosage on specific laboratory results, including the use of an artificial neural network for predicting more accurate blood use.
