- Abstract:
- Partial liquid ventilation (PLV) has been shown to improve oxygenation and lung mechanics in different models of acute lung injury. This study was designed to investigate the effects of 2 gas ventilatory strategies during PLV on gas exchange, respiratory mechanics, and hemodynamics in acute lung injury in piglets. After induction of acute lung injury, the animals were assigned randomly to 2 groups with different positive end-expiratory pressure (PEEP) levels and tidal volumes (Vt) (group A, Vt > 12.5 mL/kg; PEEP = 6 cm H2O, n = 7; group B, Vt < 9 mL/kg, PEEP = 12 cm H2O, n = 7). Thereafter, the perfluorocarbon (PFC) liquid (30 mL/kg) was instilled into the endotracheal tube. Cardiorespiratory parameters were measured at baseline, after induction of acute lung injury, and every 30 minutes up to 120 minutes. During PLV, oxygenation significantly improved with no difference between both gas ventilatory strategies. The high PEEP-moderate Vt gas ventilatory strategy reduced the inspiratory airway resistance and was associated with moderate hypercapnia. There were no significant differences in hemodynamics and respiratory compliance between both gas ventilatory strategies. The results of this pilot study suggest that oxygenation was equally improved during PLV. This effect was independent of the mode of gas ventilation. However, the high PEEP-moderate Vt gas ventilatory technique resulted in moderate hypercapnia. Copyright 2003, Elsevier Science (USA). All rights reserved.
