Randomized Controlled Trial Comparative Study Clinical TrialLung isolation during port-access cardiac surgery: double-lumen endotracheal tube versus single-lumen endotracheal tube with a bronchial blocker.
The purpose of this study was to compare the use of a double-lumen endotracheal tube to a single-lumen tube combined with a bronchial blocker for lung isolation during Port-Access cardiac surgery. ⋯ Compared with a single-lumen tube/bronchial blocker combination the double-lumen endotracheal tube required more laryngoscopy attempts and additional time to replace the tube at the end of the case but resulted in slightly better overall lung deflation.

Randomized Controlled Trial Comparative Study Clinical TrialWhich anesthetic agent alters the hemodynamic status during pediatric catheterization? Comparison of propofol versus ketamine.
To compare the effects of propofol and ketamine on systemic and pulmonary circulations in pediatric patients scheduled for elective cardiac catheterization. ⋯ In children with cardiac shunting, the principal hemodynamic effect of propofol is a decrease in systemic vascular resistance. In children with intracardiac shunting, this results in an increase in right-to-left shunting and a decrease in the ratio of pulmonary to systemic blood flow, which may lead to arterial desaturation. Ketamine did not produce these changes. The authors suggested that during cardiac catheterization in children, both the anesthesiologists and cardiologists need to know that anesthetic agents can significantly alter the hemodynamic status in children with complex congenital heart defects and affect the results of hemodynamic calculations that are important for decision-making and treatment of these patients.
