Exogenous surfactant and partial liquid ventilation: physiologic and pathologic effects.
We compared the effects of surfactant and partial liquid ventilation (PLV), and the impact of administration order, on oxygenation, respiratory system compliance (Crs), hemodynamics, and lung pathology in an animal lung injury model. We studied four groups: surfactant alone (S; n = 8); partial liquid ventilation alone (PLV-only; n = 8); surfactant followed by partial liquid ventilation (S-PLV; ...
متن کاملSmall dose of exogenous surfactant combined with partial liquid ventilation in experimental acute lung injury: effects on gas exchange, haemodynamics, lung mechanics, and lung pathology.
A combination of exogenous surfactant and partial liquid ventilation (PLV) with perfluorocarbons should enhance gas exchange, improve respiratory mechanics and reduce tissue damage of the lung in acute lung injury (ALI). We used a small dose of exogenous surfactant with and without PLV in an experimental model of ALI and studied the effects on gas exchange, haemodynamics, lung mechanics, and lu...
متن کاملPartial liquid ventilation protects lung during resuscitation from shock.
Preliminary animal experience with partial liquid ventilation (PLV) suggests that this therapy may diminish neutrophil invasion and capillary leak during acute lung injury. We sought to confirm these findings in a model of shock-induced lung injury. Sixty anesthetized rats were studied. After hemorrhage to an arterial pressure of 25 mmHg for 45 min, animals were resuscitated with blood and sali...
متن کاملComparison of exogenous surfactant therapy, mechanical ventilation with high end-expiratory pressure and partial liquid ventilation in a model of acute lung injury.
We have compared three treatment strategies, that aim to prevent repetitive alveolar collapse, for their effect on gas exchange, lung mechanics, lung injury, protein transfer into the alveoli and surfactant system, in a model of acute lung injury. In adult rats, the lungs were ventilated mechanically with 100% oxygen and a PEEP of 6 cm H2O, and acute lung injury was induced by repeated lung lav...
متن کاملDoes perfluorocarbon deoxygenate during partial liquid ventilation?
Perfluorocarbons accumulate in the dependent regions of the lungs, which may result in regional hypoxia if ventilation with oxygen is insufficient to oxygenate the dependent perfluorocarbon-filled alveoli. In this issue of Critical Care, Max et al present data that demonstrate a decrease in arterial oxygen tension (PaO2) at 30 min compared to that observed at 5 min after administration of FC 32...
