title: Emergency surgery in hematologic patients.
abstract: Patients at risk for clinically significant bleeding and who require urgent or emergent surgical procedures are encountered. Usually local causes are responsible, but a generalized hematologic defect may be uncovered. Quickly and effectively distinguishing the cause may be critical to rapid treatment and survival. A careful history, appropriate use of laboratory tests (e.g., partial thromboplastin time, prothrombin time, and platelet count), and knowledge of possible causes are key to prompt diagnosis and treatment. Bleeding from multiple sites, spontaneous bleeding, or unexpectedly severe bleeding suggests a systemic process. Immunocompromised or suppressed patients or systemically ill patients with chronic hepatic renal, lymphatic, and hematologic disorders are seen with urgent surgical problems. The key is rapid diagnosis and effective systemic and local therapy to counter the problem. The syndrome of diffuse "medical bleeding" frequently confronts the surgeon treating a patient who has received transfusions of more than 1.5 times blood volume. The coagulation defect is almost always associated with hypothermia and acidosis. Treatment consists in control of large-vessel bleeding by appropriate surgical techniques, blunt packing, and tamponade of diffuse bleeding, rapid rewarming of the patient, and adequate resuscitation for shock. Transfusion of platelets and fresh frozen plasma is empiric initially and subsequently guided by the clinical and laboratory coagulation profiles of the patient.
