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 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...
متن کاملEffects of inhaled nitric oxide on oxygenation and haemodynamic performance during one-lung ventilation in pigs
Objective: To study the effects of 20 ppm inhaled nitric oxide (iNO) on haemodynamics and systemic oxygenation during one-lung ventilation (OLV) in vivo. Design: Prospective animal study with a cross-over design. Setting: Animal laboratory of a university hospital. Subjects: Eight female pigs. Outcome measures: The pigs were anaesthetized, tracheally intubated, and mechanically ventilated. Foll...
متن کاملCerebral oxygenation monitoring using near infrared spectroscopy during one-lung ventilation in adults
BACKGROUND Changes in oxygenation occur during one-lung ventilation (OLV) due to intrapulmonary shunt. Although arterial oxygenation is generally adequate, there are no studies evaluating the effect of these changes on cerebral oxygenation. MATERIALS AND METHODS Cerebral oxygenation (rSO(2)), heart rate (HR), blood pressure (BP), oxygen saturation (SaO(2)), and end-tidal carbon dioxide (ETCO(...
متن کاملGravity is an important determinant of oxygenation during one-lung ventilation.
BACKGROUND The role of gravity in the redistribution of pulmonary blood flow during one-lung ventilation (OLV) has been questioned recently. To address this controversial but clinically important issue, we used an experimental approach that allowed us to differentiate the effects of gravity from the effects of hypoxic pulmonary vasoconstriction (HPV) on arterial oxygenation during OLV in patien...
