lüll Pulmonary embolism in the critically ill Carlbom DJ; Davidson BLChest 2007[Jul]; 132 (1): 313-24Pulmonary embolism in the critically ill requires considerations beyond anticoagulant therapy. Measurements of chamber size by echocardiography and CT and of circulating biomarkers identify higher-risk patients with moderate accuracy and may aid determination of patient acuity. Preserving right ventricular function requires judicious use of volume administration, vasopressor, and perhaps vasodilator therapies. Obstructing thrombus can be treated with fibrinolytic drugs, percutaneous instrumentation, or surgically, but these treatments may not be equally effective or safe. Anticoagulant therapy in critically ill patients is likely best administered IV. Bleeding complications should be assiduously sought but do not necessitate anticoagulant discontinuation in every case. The antidotes protamine, desmopressin acetate, factor VIII inhibitory bypass activity, and recombinant factor VIIa may each have a place in controlling anticoagulant-related bleeding. The grave prognosis of heparin-induced thrombocytopenia warrants close surveillance, with rapid switching to lepirudin, argatroban, or fondaparinux necessary if it is suspected. Retrievable vena cava filters can be lifesaving, and at least one type may be safely removed after residence of nearly 1 year.|*Critical Illness[MESH]|Anticoagulants/therapeutic use[MESH]|Fibrinolytic Agents/adverse effects/therapeutic use[MESH]|Humans[MESH]|Pulmonary Embolism/*drug therapy/*physiopathology/surgery[MESH]|Thrombosis/drug therapy/prevention & control[MESH]|Vasodilator Agents/therapeutic use[MESH]|Vena Cava Filters[MESH]|Ventricular Dysfunction, Right/drug therapy/physiopathology/prevention & control[MESH] |
