Nearly 1½ centuries ago, the clinical manifestations of drug-induced thrombocytopenia (DIT) were first described. Since that time, the disorder has become increasingly common. Despite the availability of testing to identify implicated agents in DIT, a high index of suspicion and a patient history of drug exposure remain important elements of effective assessment and management. Patricia A. Ford, MD, examines the various mechanisms of this disorder as well as new and upcoming treatments for it.

Trauma anesthesiologist Richard P. Dutton, MD, MBA, addresses a series of questions on the mechanistic theory of coagulopathy, evolving resuscitation techniques, and recent changes in the way clinicians regard the early coagulopathy of trauma. Hemorrhage is a major contributor to the dilemma of traumatic injury and its subsequent care, and patients with massive traumatic hemorrhage inevitably develop coagulopathy. More than 80% of the trauma deaths that occur in the OR do so as a result of hemorrhage. The acquired coagulopathy of trauma is an important clinical issue that continues to be studied and debated.

Listen to Jerrold H. Levy, MD, FAHA, a cardiothoracic anesthesiologist, share his insights on the prevention and management of surgical coagulopathy. Coagulopathy can prevent normal hemostatic mechanisms from functioning, thereby placing certain surgical patients at risk.
