Randomized Controlled Trial Comparative Study Clinical TrialA comparison of the effects of propofol-alfentanil versus isoflurane anesthesia on arterial oxygenation during one-lung ventilation.
To determine whether intravenous propofol-alfentanil anesthesia provides superior arterial oxygenation (Pao2) during one-lung ventilation (OLV) compared with isoflurane inhalation anesthesia. ⋯ This study does not support the theory that total intravenous anesthesia will decrease the risk of hypoxemia during OLV.

Randomized Controlled Trial Clinical TrialCardiorespiratory changes in patients undergoing pulmonary resection using different anesthetic management techniques.
Pulmonary resection may be associated with considerable alterations of the cardiorespiratory system. The ideal anesthetic regimen for these patients is not yet definitely determined. ⋯ In comparison with lobectomy patients, pneumonectomy resulted in more pronounced and sustained deterioration in right ventricular hemodynamics. The kind of anesthesia regimen did not influence most of the cardiorespiratory parameters intraoperatively, except for Qs/Qt, which was least compromised in the propofol patients during OLV. Early extubation could safely be performed in the lobectomy patients anesthetized with propofol without showing any negative cardiorespiratory effects.

Inhaled prostacyclin for treatment of pulmonary hypertension after cardiac surgery or heart transplantation: a pharmacodynamic study.
To study the effects of incremental concentrations of inhaled aerosolized prostacyclin (PGI2) on pulmonary and systemic hemodynamics after cardiac surgery or heart transplantation. ⋯ Inhaled PGI2 induces a dose-dependent selective pulmonary vasodilation and may improve RV performance after cardiac surgery complicated by pulmonary hypertension and RV failure.

Administration of propofol by target-controlled infusion in patients undergoing coronary artery surgery.
To study the predictive performance of a target-controlled infusion (TCI) system of propofol in patients undergoing coronary bypass graft (CABG) surgery, using a referenced pharmacokinetic set derived from healthy patients. Also, to determine the propofol concentrations required for clinically acceptable induction and maintenance of anesthesia when combined with midazolam as premedication and a continuous alfentanil infusion and to study the hemodynamic stability of this technique. ⋯ In this group of patients undergoing CABG surgery, the TCI system used underestimated the measured propofol concentrations. However, the predictive performance of the selected mean pharmacokinetic parameters derived from healthy patients was acceptable during the whole surgical procedure.
