The Jackson table has minimal effects on cardiac function because it does not elevate abdominal and thoracic pressures. In addition, it decreases venous congestion and increases exposure of the surgical field. However, the hips and knees are flexed with inappropriate padding, and venostasis is promoted and increased. Pulmonary thromboembolism (PTE) is fatal; thus immediate diagnosis and treatment are essential. However, clinical signs of intraoperative PTE are difficult to discern. Thrombolytic therapy can be considered as first-line therapy, but bleeding limits its use. The authors report a case of PTE resulting from patient positional change after spine surgery, and the use of immediate postoperative recombinant tissue-type plasminogen activator.

Acute lung injury (ALI) is a common, life-threatening cause of acute respiratory failure, which is ultimately caused by a variety of local and systemic insults. Alterations in the coagulation and fibrinolysis profiles are present in almost all the patients suffering with ALI. The classic histologic findings in ALI patients include alveolar fibrin formation and microthrombi in the pulmonary vasculature. Decreased circulating levels of protein C and increased concentrations of thrombomodulin are present in patients with septic and nonseptic ALI. The circulating and pulmonary concentrations of plasminogen activator inhibitor-1 (PAI-1) are increased in the setting of ALI, and the degree of elevation in the PAI-1 level directly correlates with mortality. The need for new specific therapies has led a number of investigators to examine the role of altered coagulation and fibrinolysis in the pathogenesis of ALI. This review summarizes the current understanding of coagulation and fibrinolysis in ALI with an emphasis on the pathways that could be potential therapeutic targets, including the tissue factor pathway, the protein C pathway and the modulation of fibrinolysis via plasminogen activator inhibitor-1.
