Arterial oxygenation during one-lung ventilation: combined versus general anesthesia.
UNLABELLED The optimal anesthetic management of patients undergoing thoracotomy for pulmonary resection has not been definitely determined. We evaluated whether general i.v. anesthesia (propofol-fentanyl) provides superior PaO2 during one-lung ventilation (OLV) compared with thoracic epidural anesthesia (TEA) with supplemental local and general anesthetics. We studied 60 patients who had prolon...
متن کاملEffects of propofol vs sevoflurane on arterial oxygenation during one-lung ventilation.
BACKGROUND The inhibitory effect of anaesthetic agents on hypoxic pulmonary vasoconstriction may depend upon their dose, especially when using a volatile agent. The aim of this randomized open study was to compare the effects of sevoflurane and propofol, as primary anaesthetic agents, on oxygenation during one-lung ventilation (OLV), with their administration being adjusted to maintain bispectr...
متن کاملImpact of Left Heart Bypass on Arterial Oxygenation During One-Lung Ventilation for Thoracic Aortic Surgery.
OBJECTIVE The aim of this study was to reveal the mechanism of improved arterial oxygenation by measuring the changes in oxygenation before and after initiation of left heart bypass (LHB) during one-lung ventilation (OLV) for thoracic aortic surgery. DESIGN Prospective, observational study. SETTING Single-institution, private hospital. PARTICIPANTS The study comprised 50 patients who unde...
متن کاملVentilation and arterial oxygenation during thoracic surgery.
Considerable interest has been shown in recent years in the relative distributions of alveolar blood and gas flows under various conditions. During thoracic surgical procedures in the lateral position, with one hemithorax open and with controlled ventilation of the lungs, a severe degree of maldistribution of blood and gas may be expected. The upper lung may be freely expanded, retracted by the...
متن کاملBiologically variable ventilation improves oxygenation and respiratory mechanics during one-lung ventilation.
BACKGROUND Hypoxemia is common during one-lung ventilation (OLV). Atelectasis contributes to the problem. Biologically variable ventilation (BVV), using microprocessors to reinstitute physiologic variability to respiratory rate and tidal volume, has been shown to be advantageous over conventional monotonous control mode ventilation (CMV) in improving oxygenation during the period of lung reinfl...
