Pulmonary emboli risk reduction.
Pulmonary embolism is a major cause of death in hospitalized patients in the United States. Significant morbidity is a characteristic of this phenomenon and its common antecedent, deep venous thrombosis. Research has shown that pulmonary embolism is rarely a consequence of superficial venous thrombosis. Because the signs and symptoms of these disorders are often nonspecific and not readily apparent, prevention is the goal of patient care. Nurses play a critical role in the prevention process. The recognition of persons at risk, the assessment of these patients for early signs and symptoms, and the institution of prophylactic measures to minimize the effect of any existing factors or to deter their development are essential components of nursing care. The administration of anticoagulation therapy, with the concomitant monitoring of its effectiveness, and the education of persons regarding precautions associated with the indicated medications and relevant lifestyle modifications are also fundamental aspects of care. This article provides a review of risk factors associated with pulmonary embolism and deep venous thrombosis, particularly prolonged immobility and surgery involving the abdomen or lower extremities, as well as a review of the respective etiologies, most notably those encompassing Vichow's triad. In addition, current modalities to diagnose, treat, and prevent these allied disorders are discussed, as well as the associated nursing management.
