Randomized Controlled Trial Comparative Study Clinical TrialGlucose versus lactated Ringer's solution during pediatric cardiac surgery.
Whether intraoperative fluid infusion should contain glucose during pediatric cardiac surgery remains controversial. This study was performed to compare the effects of glucose and glucose-free solutions on blood glucose and blood insulin levels during total repair of congenital heart diseases. ⋯ Glucose withdrawal during pediatric cardiac surgery induces threatening hypoglycemia during the prabypass period, and moderate intraoperative glucose administration (2.5 mg/kg/min) is not responsible for major hyperglycemia.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of pulsatile versus nonpulsatile perfusion on the postcardiopulmonary bypass aortic-radial artery pressure gradient.
To investigate whether the type of perfusion, pulsatile (PP) or nonpulsatile (NP), has any effect on the pressure gradient that exists between the aortic root and the radial artery after cardiopulmonary bypass (CPB). ⋯ Pulsatile perfusion had no effect on the aortic root radial artery blood pressure gradient after CPB in elective CABG surgery patients.

Randomized Controlled Trial Clinical TrialThermodilution cardiac output measurement during simultaneous volume infusion through the venous infusion port of the pulmonary artery catheter.
To determine the effect on thermodilution cardiac output (TDCO) measurements of continuous volume infusion through the right atrial venous infusion port of the pulmonary artery catheter. ⋯ Rapid continuous infusion of fluid through the venous infusion port of the pulmonary artery catheter significantly limits the accuracy of simultaneous TDCO measurements. Optimally, TDCO measurements should be avoided during rapid volume infusion.

Early extubation after mitral valve surgery: a target-controlled infusion of propofol and low-dose sufentanil.
In the current study, the use of a target-controlled infusion of low-dose propofol was combined with a continuous infusion of sufentanil for patients undergoing mitral valve surgery. The purpose of the study was to evaluate the hemodynamic stability, the time to awakening and spontaneous ventilation, and the feasibility in an early extubation setting of a total intravenous anesthetic technique. ⋯ The simplicity of the method with only one change in infusion rate is a major advantage. The technique permits predictable recovery and return to spontaneous ventilation in all patients. Its use in patients entering early extubation protocols is appealing for its reproducibility, simplicity, and safety.
