Randomized Controlled Trial Comparative Study Clinical TrialEffects of thoracic epidural meperidine on arterial oxygenation during one-lung ventilation in thoracic surgery.
To compare the effects that the use of general intravenous anesthesia (propofol-fentanyl) (GA) or general anesthesia combined with thoracic epidural anesthesia with meperidine (TEA-M) may have on arterial oxygenation during one-lung ventilation (OLV). ⋯ It is concluded that GA combined with TEA-M (2 mg/kg) do not affect arterial oxygenation during OLV in thoracic surgery.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of site of venous protamine administration, previously alleged risk factors, and preoperative use of aspirin on acute protamine-induced pulmonary vasoconstriction.
To determine whether the incidence of protamine-induced pulmonary vasoconstriction (PIPV) is influenced by central venous versus peripheral venous infusion of protamine and whether aspirin ingestion within a week of surgery would decrease the incidence of PIPV. ⋯ Although the site of venous protamine administration does not influence incidence of PIPV, aspirin ingestion within 1 week of surgery may decrease it. These data also confirmed other studies suggesting that previous protamine administration predisposes to this protamine reaction.

Randomized Controlled Trial Comparative Study Clinical TrialProtective effect of antioxidants on pulmonary endothelial function after cardiopulmonary bypass.
Pulmonary endothelium-dependent vasodilation is impaired after cardiopulmonary bypass. One explanation might be the generation of reactive oxygen species during the period without flow in the pulmonary artery. The aim of the current study was to investigate if treatment with antioxidants could improve pulmonary endothelial function after cardiopulmonary bypass and influence the blood oxidative status. ⋯ The better maintained endothelium-dependent vasodilation after cardiopulmonary bypass in the treatment group indicated that antioxidant therapy reduced endothelial dysfunction.

Comparative StudyDoes gender influence resource utilization in patients undergoing off-pump coronary artery bypass surgery?
The purpose of the present study was to examine if gender influences duration of tracheal intubation, blood transfusion needs, intensive care unit length of stay (ICULOS), postoperative length of stay (PLOS), and total length of stay (LOS) in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. ⋯ Female sex was a predictor of increased blood transfusion and longer PLOS and LOS in patients undergoing OPCAB surgery. The study implies that female sex does not predict increased duration of tracheal intubation and mechanical ventilation and ICULOS in this group of patients. Females undergoing OPCAB surgery require increased resource utilization as measured by increases in blood transfusion, PLOS, and LOS.

Comparative StudyNoninvasive carbon dioxide monitoring during one-lung ventilation: end-tidal versus transcutaneous techniques.
To compare transcutaneous CO(2) (TCCO(2)) and end-tidal CO(2) (ETCO(2)) monitoring during one-lung ventilation (OLV). ⋯ During OLV, TCCO(2) monitoring provides a more accurate estimate of PaCO(2) than ET techniques.
