Randomized Controlled Trial Comparative Study Clinical TrialProtective effect of antioxidants on pulmonary endothelial function after cardiopulmonary bypass.
Pulmonary endothelium-dependent vasodilation is impaired after cardiopulmonary bypass. One explanation might be the generation of reactive oxygen species during the period without flow in the pulmonary artery. The aim of the current study was to investigate if treatment with antioxidants could improve pulmonary endothelial function after cardiopulmonary bypass and influence the blood oxidative status. ⋯ The better maintained endothelium-dependent vasodilation after cardiopulmonary bypass in the treatment group indicated that antioxidant therapy reduced endothelial dysfunction.

Comparative Study Clinical TrialDifficult laryngoscopy: incidence and predictors in patients undergoing coronary artery bypass surgery versus general surgery patients.
Cardiac surgery patients might have a higher incidence of difficult laryngoscopy than the general population because of older age, dental problems, and obesity. The authors estimated the incidence and predictors of difficult laryngoscopy in coronary artery bypass surgery patients. ⋯ Difficult laryngoscopy was more frequent in cardiac surgery patients (10% v 5.2%). Older age and limited neck movement, but not cardiac surgery per se, were independent predictors of difficult laryngoscopy.

Comparative StudyNoninvasive carbon dioxide monitoring during one-lung ventilation: end-tidal versus transcutaneous techniques.
To compare transcutaneous CO(2) (TCCO(2)) and end-tidal CO(2) (ETCO(2)) monitoring during one-lung ventilation (OLV). ⋯ During OLV, TCCO(2) monitoring provides a more accurate estimate of PaCO(2) than ET techniques.

Comparative Study Clinical TrialComparison of minithoracotomy and conventional sternotomy approaches for valve surgery.
To compare patients undergoing valve surgery through a minithoracotomy approach with a matched group undergoing conventional valve surgery. ⋯ These results suggest that valve surgery is feasible in many cases through minithoracotomy. Nevertheless, this approach increases surgical complexity and in this comparative study no significant benefit was shown.
