Deterioration of gas exchange during one-lung ventilation (OLV) is caused by both total collapse of the nondependent lung and partial collapse of the dependent lung. Alveolar recruitment maneuver improves lung function during general anesthesia. The objective of this study was to investigate whether there is an indirect relationship between the changes of CO2 expirogram and the selective lung r...

INTRODUCTION Adequate blood oxygenation and ventilation/perfusion matching should be main goal of anaesthetic and intensive care management. At present, one of the methods of improving gas exchange restricted by ventilation/perfusion mismatching is independent ventilation with two ventilators. Recently, however, a unique device has been developed, enabling ventilation of independent lungs in 1:...

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...

Noninvasive breath analysis may provide valuable information for cancer recognition if disease-specific volatile biomarkers could be identified. In order to compare nondiseased and diseased tissue in vivo, this study took advantage of the special circumstances of one-lung ventilation (OLV) during lung-surgery. 15 cancer patients undergoing lung resection with OLV were enrolled. From each patien...

Hemorrhagic shock causes a reduction in oxygen supply to tissues leading to increased reactive oxygen species resulting in lung injury. Often mechanical ventilation is required as supportive treatment; however, ventilation can also induce lung injury and apoptosis. The purpose of this study was to examine the effects of three modes of controlled mechanical ventilation: volume control, pressure ...

Prevention of iatrogenic injury due to ventilation of a heterogeneous lung requires knowledge of dynamic regional events occurring within the tidal cycle. Quantitative bedside imaging techniques that are sensitive to regional mechanics and tidal events hold potential for information delivery that cannot be realized by pressure-volume monitoring alone.

BACKGROUND Minimal access mediastinal surgery (MAMS) is usually performed under general anaesthesia with double lumen tubes (DLT). The aim of this study is to evaluate two lung ventilation through single lumen tubes (SLT) during thoracoscopic sympathectomy for hyperhidrosis and thoracoscopic thymectomy for myasthenia gravis. METHODS In this prospective non-randomized study, MAMS was performed...

Using a single-lumen tracheal tube, collapse of the nonventilated lung can be achieved by carbon dioxide insufflation into the contralateral closed intrapleural chest cavity to a pressure as low as 5 mmHg. However, this technique may create a physiological response very similar to that of a unilateral tension pneumothorax, with a consequent hemodynamic instability secondary to decreased venous ...
