Coronary artery bypass grafting: an off-pump versus on-pump review.

摘要: There has been a proliferation in the number of coronary artery bypass grafts (CABG) being performed without use cardiopulmonary (CPB). However, benefits off-pump grafting (OPCAB) are still determined. The aim this retrospective review was to compare perioperative outcomes CPB patients with OPCAB and identify most likely benefit from procedure. We reviewed data all isolated CABG at two metropolitan hospitals for period August 2000 September 2001. groups (OPCAB vs. CPB) were further divided into subgroups identifying by their predicted mortality (higher-risk lower-risk) distal graft anastomoses received (1, 2, 3, 4, or 5). A p value less than .05 considered significant. Out total 882 patients, 46.2% cases. Both similar terms demographics risk mortality. Intraoperatively, had fewer (2.4 +/- 1.0 3.2 1.0, < .001). Postoperatively, group chest drainage (889 588 989 662 mls, .001), sustained strokes (0.2 1.9%, .05), transfused (15.4 32.5%, .001) discharged earlier (7.3 5.6 8.5 9.1 days, .05). For higher-risk associated reoperations bleeding (1.3 6.4%, lower stroke rate (0 3.2%, trend toward (7.1 15.1%, = .08). lower-risk patients' incidences (0.5% 1.4% group), rates (0.5 0.5%) similar. Comparisons revealed that only single-grafted statistically postoperative complications, reduced drainage, shorter intensive care stay. Differences between either operation transfusion significant one three grafted while stays having four grafts. These results suggest is reduction morbidity, particularly within patients. diminished an increasing performed.
