  • THE EFFECTS OF LIQUID VENTILATION ON CARDIOPULMONARY FUNCTION IN PRETERM LAMBS PEDIATRIC RESEARCH Shaffer, T. H., Douglas, P. R., Lowe, C. A., Bhutani, V. K. 1983; 17 (4): 303-306

    Abstract:

    The effects of fluorocarbon ventilation on cardiopulmonary function were studied in 8 preterm lambs, 132-136 days gestation. After mechanical ventilation with 100% oxygen (control period), the lambs were ventilated with fluorocarbon (PIO2 = 622 torr). The liquid was then removed from their lungs and gas ventilation resumed (recovery period). During normothermic liquid breathing the alveolar-arterial O2 gradient (A-a DO2) decreased (P less than 0.01) from control by 154 torr and remained decreased (P less than 0.05) by 85 torr during recovery. Dynamic lung compliance (CL) increased 50% (P less than 0.05); PaO2 increased 50% (P less than 0.05); and PaCO2 decreased 29% (P less than 0.01) as compared to control values. The change in A-a DO2 and PaO2 before and after liquid ventilation was correlated (r = 0.79 and P less than 0.01) with control CL. There was a gradual decrease (P less than 0.01) in mean arterial pressure from 62 +/- 5.4 torr (control) to 53,1 +/- 9,3 torr (recovery); however, there were no significant alterations in mean central venous pressure, heart rate, or mean electrical axis.
