Effect of Anesthetics on Oxygenation and Microcirculation During One-lung Ventilation
研究概览
详细说明
Patients undergoing thoracic surgery including one-lung ventilation will be randomized to receive intravenous (propofol) or inhalational (desflurane) anesthetic.
Systemic oxygenation can be evaluated by measuring partial pressure of oxygen in arterial blood analysis. Microcirculatory parameters can be obtained from vascular occlusion test. Among those parameters, recovery slope during vascular occlusion test is known to reflect recruitment of microvasculature in response to hypoxic or ischemic insult. In this study, we will compare arterial partial pressure of oxygen and recovery slope during one-lung ventilation between propofol and desflurane group.

实验性的：propofol
Propofol is used as a maintenance anesthetic to patients in the propofol group.
Intervention: propofol infusion by target-controlled infusion for maintaining anesthesia propofol (Fresofol MCT 2%) target effect site concentration: 4~5 mcg/ml, during general anesthesia

实验性的：desflurane
Desflurane is used as a maintenance anesthetic to patients in the desflurane group. Intervention: Desflurane administration for maintaining anesthesia desflurane (Suprane) inhalation as 6~8 vol% during general anesthesia |
Patients are randomized to receive intravenous anesthetic (propofol) or inhalational anesthetic (desflurane) as a maintenance anesthetic.
