Randomized Controlled Trial Comparative Study Clinical TrialClosure of atrial septal defects without cardiopulmonary bypass: the sandwich operation.
Cardiopulmonary bypass has adverse effects on patient physiology. A prospective randomized trial was undertaken to evaluate closure of atrial septal defects with or without cardiopulmonary bypass. ⋯ Closure of atrial septal defects without cardiopulmonary bypass can be done effectively. Adverse effects of cardiopulmonary bypass can be avoided, as shown by improvements of postoperative parameters with the sandwich operation.

Comparative StudyCoronary artery bypass grafting in non-dialysis-dependent mild-to-moderate renal dysfunction.
The effect of mild-to-moderate elevation of preoperative serum creatinine levels on morbidity and mortality from coronary artery bypass grafting has not been investigated in a large multivariable model incorporating preoperative and intraoperative variables. Our first objective was to ascertain the effect of a mild-to-moderate elevation in the preoperative serum creatinine level on the need for mechanical renal support; the duration of special care and total postoperative stay; the occurrence of infective, respiratory, and neurologic complications; and hospital mortality. Our second objective was to ascertain which patient variables contributed to an increase in the serum creatinine level in association with coronary artery bypass grafting. ⋯ A mild elevation (130-149 micromol. L(-1)) in the preoperative serum creatinine level significantly increases the need for mechanical renal support, the duration of special care and total postoperative stay, and the in-hospital mortality. As the preoperative serum creatinine level increases further (> or =150 micromol. L(-1)), this effect is more pronounced. No significant difference in outcome was observed between the use of cardioplegia or crossclamp fibrillation for myocardial protection.

Comparative StudyPneumonectomy for malignant disease: factors affecting early morbidity and mortality.
The purpose of this report is to analyze factors affecting morbidity and mortality after pneumonectomy for malignant disease. ⋯ Multiple factors adversely affected morbidity and mortality after pneumonectomy for malignant disease. Appropriate selection and meticulous perioperative care are paramount to minimize risks in those patients who require pneumonectomy.

Comparative StudyNeurologic outcome after ascending aorta-aortic arch operations: effect of brain protection technique in high-risk patients.
We sought to assess the optimal strategy for avoiding neurologic injury after aortic operations requiring hypothermic circulatory arrest. ⋯ The occurrence of stroke is principally determined by patient- and disease-related factors, but use of antegrade cerebral perfusion can significantly reduce the occurrence of temporary neurologic dysfunction.
