Comparative StudyOctogenarians undergoing coronary artery bypass graft surgery: resource utilization, postoperative mortality, and morbidity.
The purpose of the present study was to examine resource utilization in octogenarians undergoing coronary artery bypass grafting (CABG) and compare it with usage in their younger cohorts at a tertiary care heart center. The resources examined were time to extubation, packed red blood cell transfusions, intensive care unit (ICU) length of stay (LOS), and preoperative and postoperative LOS. The study also examined differences in postoperative morbidity and mortality. ⋯ The results demonstrated that octogenarians undergoing CABG required increased resource utilization and had significantly higher morbidity, with increased incidence of postoperative renal failure, neurologic complications, and 30- day mortality. Age 80 years or older was an independent predictor of increased resource utilization, postoperative morbidity, and mortality.

Comparative StudySerum cardiac troponin-I elevation in neonatal cardiac surgery is lesion-dependent.
Serum cardiac troponin-I (cTn-I) is a marker for myocardial injury in adults that undergoes developmental isoform change. To determine its utility as a myocardial injury marker in neonates, the authors examined the perioperative pattern of cTn-I elevation in neonates undergoing surgical repair for hypoplastic left-heart syndrome (HLHS) and transposition of great arteries (TGA). ⋯ It was found that perioperative elevations in serum cTn-I in neonates with TGA and HLHS were influenced by duration of aortic cross-clamp application, CPB, and the presence of VSD.

Comparative StudyAutologous blood donation in cardiac surgery: reduction of allogeneic blood transfusion and cost-effectiveness.
The purpose of this study was to assess transfusion requirements in patients undergoing cardiac surgery with and without autologous blood donation and to calculate the costs of predonation from the hospital perspective. ⋯ Autologous blood donation significantly reduces allogeneic blood requirement in cardiac surgery. If adjusted for diagnosis and gender, autologous blood donation is a cost-effective alternative to reduce allogeneic blood consumption.

Comparative StudyOff-pump coronary artery bypass attenuates transient hepatocellular damage after myocardial revascularization.
Cardiopulmonary bypass (CPB) affects hepatocellular integrity and occasionally results in liver dysfunction after cardiac surgery. Performing coronary artery bypass graft surgery without CPB may help to reduce the risk of this complication and better preserve perioperative liver function. This study compared perioperative hepatocellular damage in patients undergoing on-pump and off-pump bypass surgery. ⋯ CPB induced transient subclinical hepatocellular damage, whereas off-pump revascularization attenuated this damage.
