Hematologic Emergencies T2 CURRENT Diagnosis & Treatment Emergency Medicine, 7e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-0-07-170107-5 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=55756032 RD 2024/04/25 AB Most bleeding seen in the emergency department is due to trauma, the result of local wounds, lacerations, or other structural lesions that occur in patients with normal hemostasis. Conversely, bleeding from multiple sites, bleeding from untraumatized sites, delayed bleeding several hours after trauma, and bleeding into deep tissues or joints suggest the possibility of a bleeding disorder. Historical data for the presence of a congenital bleeding disorder include the presence or absence of unusual or abnormal bleeding in the patient and other family members and the possible occurrence of excessive bleeding after dental extractions, surgical procedures, or trauma. Many patients with abnormal bleeding have an acquired disorder, commonly due to liver disease or drug use (particularly ethanol, aspirin, nonsteroidal anti-inflammatory drugs [NSAIDs], warfarin, and antibiotics).
