Abstract:
BACKGROUND:Sustained lung inflation (SLI) applied at birth has been demonstrated to lead to clearance of lung fluid and achievement of a precocious functional residual capacity in animal studies. OBJECTIVES:To verify if the application of SLI in preterm infants at birth may reduce the need for mechanical ventilation and improve their respiratory outcome. METHODS:We prospectively studied 89 infants with respiratory distress (gestational age (GA) 28.1 ± 2.2 weeks) treated at birth with a SLI (25 cm H(2)O, sustained for 15 s) in addition to AAP recommendations versus a historical control group (n = 119; GA 28.1 ± 2.0 weeks) treated without SLI with the same device (controlled positive end-expiratory pressure of 5 cm H(2)O). RESULTS:The SLI group had less need for (51 vs. 76%, p < 0.0001) and shorter duration of mechanical ventilation (5 ± 11 vs. 11 ± 19 days, p = 0.008), a more frequent occurrence of exclusive nasal continuous airway pressure support (49 vs. 24%, p < 0.0001) and INtubation-SURfactant-Extubation (INSURE) treatment (16 vs. 3%, p = 0.01), less need for surfactant (45 vs. 61%, p = 0.027) and postnatal steroids (10 vs. 25%, p = 0.01), a shorter duration of oxygen therapy (21 ± 27 vs. 31 ± 31 days, p = 0.016), and, finally, a lower occurrence of bronchopulmonary dysplasia in survivors (7 vs. 25%, p = 0.004). Multiple regression analysis showed that 23-27 weeks of GA and birth weight <750 g increased the risk of mechanical ventilation, while a clinical risk index for babies (CRIB) score <3 as well as INSURE strategy and SLI treatment in the delivery room decreased it. CONCLUSIONS:The application of a SLI at birth in preterm infants with respiratory distress may decrease the need for mechanical ventilation without inducing evident adverse effects.
