Resume L'hypoxemie observee durant la ventilation du poumon inferieur depend d'un grand nombre de facteurs, notamment des facteurs anatomiques et de l'intensite de la vasoconstriction hypoxique. Le but de ce travail a ete d'analyser l'apport eventuel de la bronchospirometrie dans la prediction du degre d'hypoxemie peroperatoire. Douze patients, devant etre operes d'une pneumonectomie, d'une lobectomie, d'une resection economique ou d'une decortication ont ete inclus dans ce travail. Les donnees… Expand

A Comparison of Two-Lung High Frequency Positive Pressure Ventilation and One-Lung Ventilation plus 5 cm H2O Non-Ventilated Lung CPAP, in Patients Undergoing Anaesthesia for Oesophagectomy
Two-lung high frequency positive pressure ventilation has some advantages over one- lung ventilation during the thoracotomy phase of oesophagectomy because it is easy to administer, does not significantly compromise the surgical exposure and is associated with fewer severe undesirable physiological disturbances.

Techniques de ventilation artificielle sur un seul poumon en cours de thoracotomie
Cette etude montre que le seul moyen efficace d'ameliorer l'oxygenation en cas of ventilation sur un seul poumon est d'augmenter F io 2 . Expand
Blood gas and pH studies during use of the carlens catheter
Arterial oxygénation is usually adequate if high concentrations of oxygen are used, the pulmonary artery is ligated as soon as possible during pneumonectomy, and atelectasis in the dependent lung is prevented by vigorous ventilation. Expand
One‐Lung Ventilation and Hypoxic Pulmonary Vasoconstriction: Implications for Anesthetic Management
La majorite du desequilibre ventilation/perfusion est eliminee au cours d'une pneumonectomie par une ligature autour d'une artere pulmonaire du poumon non ventile aussitot que possible qui elimineExpand
Observations during endobronchial anaesthesia. II. Oxygenation.
An increase in shunt between the beginning and the end of the operation was found to correlate with a fall in the ventilation volume of the dependent lung during OLV, probably because of uptake of residual oxygen in the unventilated lung. Expand
Pulmonary Oxygen Exchange during Endobronchial Anesthesia: Effect of Tidal Volume and PEEP
The authors studied the effects of VT at 8 and 16 per cent total lung capacity, at zero end-expiratory pressure (ZEEP), and at 10 cmH2O PEEP in 16 patients in the lateral position and found there was considerable variation in PaO2 and Q/Q among patients. Expand
Halothane and Isoflurane Do Not Decrease Pao2 during One‐Lung Ventilation in Intravenously Anesthetized Patients
The primary conclusion is that H and IF do not further impair arterial oxygenation during one-lung ventilation in intravenously anesthetized patients undergoing thoracotomy and that these drugs probably did not inhibit hypoxic pulmonary vasoconstriction During one- lung ventilation. Expand
Optimization of Arterial Oxygenation during One‐Lung Anesthesia
It is concluded that arterial oxygenation can be optimized during one-lung anesthesia by oxygen insufflation of the upper deflated lung at 10 cm H2O pressure while the lower lung is ventilated with zero end-expiratory pressure. Expand
Hypoxia‐induced Pulmonary Vasoconstriction in Man: Inhibition due to Diethyl Ether and Halothane Anesthesia
Animal investigations have revealed that pulmonary hypoxia‐induced vasoconstriction (a local mechanism which redistributes pulmonary blood flow from poorly to more amply ventilated regions) is abolished by commonly used inhalation anesthetics. Expand
