  • Title: Epidural cooling for spinal cord protection during thoracoabdominal aortic aneurysm repair (a case study).
    Author: Downey C.
    Journal: Can Oper Room Nurs J; 2000 Oct; 18(3):9-14. PubMed ID: 11899322.
    Abstract:
    Aneurysms result from damage to artery walls as a result of underlying athrosclerotic and/or thromboembolic disorders. A thoracoabdominal aortic aneurysm involves vessel damage and wall weakening in the thoracic and abdominal segments of the aorta. Thoracoabdominal aortic aneurysm repair is considered to be high risk due to the nature of the intervention that requires an extensive incision with clamping of the thoracic aorta above the renal arteries. Clamping of the aorta renders all areas distal to the clamp at high risk for ischemic trauma especially to the spinal cord where the risk of neurological deficits postoperatively is 7-16% (Cambria, et al., 1997; Davison, et al., 1997). Several adjunct interventions have been tried to reduce the risk of spinal cord injury associated with the ischemia of cross clamping. Epidural cooling has been successful as an adjunct in reducing the neurological deficits. A preoperative nursing assessment indicating the appropriate nursing diagnoses and nursing care required for this patient, allowed for individualization of the plan needed to include this new procedure and plan for best patient outcomes and practices.
