Application of CO2 waveform in the alveolar recruitment maneuvers of hypoxemic patients during one-lung ventilation
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...
متن کاملUsing recruitment maneuvers to decrease tidal volumes during one-lung ventilation.
N O anesthesiologist has failed to be amazed at the process of reexpanding the lung after thoracotomy. A long sustained breath turns a meaty atelectatic organ into a pink and airy one, one acinar unit at a time. During thoracic surgeries, the one ventilated lung has to sustain the patient. Overcoming hypoxemia is the battle for thoracic anesthesiologists. What is the best ventilatory strategy t...
متن کاملArterial 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 کاملPressure-controlled versus volume-controlled ventilation during one-lung ventilation for thoracic surgery.
BACKGROUND Pressure-controlled ventilation (PCV) has been suggested as a tool to improve oxygenation during one-lung ventilation (OLV) for patients undergoing thoracic surgery. In this study we investigated whether PCV results in improved arterial oxygenation compared with volume-controlled ventilation (VCV) during OLV. METHODS Fifty-eight patients with good preoperative pulmonary function sc...
متن کاملVentilatory protective strategies during thoracic surgery: effects of alveolar recruitment maneuver and low-tidal volume ventilation on lung density distribution.
BACKGROUND The increased tidal volume (V(T)) applied to the ventilated lung during one-lung ventilation (OLV) enhances cyclic alveolar recruitment and mechanical stress. It is unknown whether alveolar recruitment maneuvers (ARMs) and reduced V(T) may influence tidal recruitment and lung density. Therefore, the effects of ARM and OLV with different V(T) on pulmonary gas/tissue distribution are e...
