Comparative StudyMeasuring cardiac output in one-lung ventilation: a comparison of pulmonary artery and transpulmonary aortic measurements in pigs.
The agreement between cardiac output measurements via pulmonary artery thermodilution (CO[PA]) and transpulmonary aortic thermodilution (CO[AT]) during one-lung ventilation was studied. ⋯ The pulmonary artery thermodilution and the transpulmonary aortic thermodilution techniques both accurately measure cardiac output during one-lung ventilation.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of epsilon aminocaproic acid and tranexamic acid in pediatric cardiac surgery.
This study compared the efficacy of aminocaproic acid and tranexamic acid in reducing postoperative blood loss, as well as blood and blood product requirements in children with cyanotic congenital heart disease. ⋯ Aminocaproic acid and tranexamic acid are equally effective in reducing postoperative blood loss, as well as blood and blood product requirements in children with cyanotic heart disease undergoing corrective surgery as compared with the control group.

Randomized Controlled Trial Clinical TrialDecreased concentration of antithrombin after preoperative therapeutic heparin does not cause heparin resistance during cardiopulmonary bypass.
To determine if preoperative heparin therapy causes an increase in the incidence of intraoperative heparin resistance by reducing the concentration of antithrombin in plasma. ⋯ Preoperative heparin causes an increased incidence of heparin resistance and reduced antithrombin concentrations. However, heparin resistance was not causally related to reduced antithrombin because antithrombin concentrations were not different between heparin-resistant and heparin-responsive patients in the POHI group.

Comparative Study Clinical TrialWhat is the optimal device for carbon dioxide deairing of the cardiothoracic wound and how should it be positioned?
To compare recently described insufflation devices for efficient carbon dioxide (CO(2)) deairing of the cardiothoracic wound and to determine the importance of their position. ⋯ For efficient deairing, CO(2) has to be delivered from within the wound cavity. The gas-diffuser was the most efficient device. In contrast to a gas-diffuser, a multiperforated catheter or a gauze sponge is unsuitable for CO(2) deairing because they will stop functioning when they get wet in the wound.
