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 Comparative Study Clinical TrialPropofol-alfentanil versus fentanyl-midazolam in coronary artery surgery.
To compare intraoperative hemodynamics profiles and recovery characteristics of propofol-alfentanil with fentanyl-midazolam anesthesia in elective coronary artery surgery. ⋯ Propofol-alfentanil anesthesia provides good intraoperative hemodynamics and allows early extubation after coronary artery surgery.

Impact of pleurotomy, continuous positive airway pressure, and fluid balance during cardiopulmonary bypass on lung mechanics and oxygenation.
To determine effects of surgical pleurotomy, continuous positive airway pressure, and fluid balance during cardiopulmonary bypass (CPB) on lung mechanical properties and indices of oxygenation. ⋯ These findings suggest that pleurotomy before CPB and positive fluid balance during CPB enhance postbypass pulmonary edema and/or atelectasis, as demonstrated by acute changes in respiratory mechanics and indices of oxygenation. Low levels of CPAP applied during CPB did not significantly change either mechanical properties or oxygenation.

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.
