The IOLMaster was more accurate and reproducible than the contact ultrasonographic technique.

The overall volume of thoracic surgery cases was not significantly different after the implementation of the 80-hour work-week restriction. The total number of cardiac cases logged was substantially less during the same time period, and therefore as a result, the total number of cases performed after the implementation of the work-hour restrictions was also reduced. Although recent data have not shown an improvement in patient outcomes after restriction of resident work hours, we speculate that in a time of increasingly complex cases, reduction in resident case volumes caused by work-hour restrictions and decreasing cardiac cases might lead to inadequate operative experience.

Aprotinin preserves myocardial biochemical function during cold storage. This preservation of biochemical function is mediated through suppression of the release, uptake, and activity of tumor necrosis factor alpha.
