Review Comparative Study
Prevention of venous thromboembolism in North America: results of a survey among general surgeons.
The purpose of this study was to analyze current attitudes toward the prevention of postoperative venous thromboembolism among North American general surgeons. ⋯ North American surgeons who responded to this survey are well aware of the problem of venous thromboembolism and their approach to prevention has been significantly modified in the last 10 years. Compared with similar European surveys this survey reveals a higher implementations of physical methods such as intermittent pneumatic compression and elastic stockings. Because of the limited response rate and possibility of sampling bias, these findings should be interpreted with caution.

Clinical Trial
Monitoring for spinal cord ischemia by use of the evoked spinal cord potentials during aortic aneurysm surgery.
This clinical study was to evaluate changes of evoked spinal cord potentials (ESCPs) elicited by direct spinal cord stimulation and to determine their relation to spinal cord ischemia during aortic aneurysm surgery. ⋯ Lumbar descending ESCP was the best method for the spinal cord ischemia during aortic aneurysm surgery. Spinal cord ischemia could be detected by diminution in the amplitude of the late negative wave of lumbar descending ESCP. The recovery amplitude of the late negative wave after declamping correlated with the neurologic outcome.
