Randomized Controlled Trial Comparative Study
Crossover study of assist control ventilation and neurally adjusted ventilatory assist.
Some studies of infants with acute respiratory distress have demonstrated that neurally adjusted ventilator assist (NAVA) had better short-term results compared to non-triggered or other triggered models. We determined if very prematurely born infants with evolving or established bronchopulmonary dysplasia (BPD) had a lower oxygenation index (OI) on NAVA compared to assist control ventilation (ACV). Infants were studied for 1 h each on each mode. ⋯ The mean OI after 1 h on NAVA was 7.9 compared to 11.1 on ACV (p = 0.0007). The FiO2 (0.36 versus 0.45, p = 0.007), PIP (16.7 versus 20.1 cm H2O, p = 0.017) and MAP (9.2 versus 10.5 cm H2O, p = 0.004) were lower on NAVA. Compliance was higher on NAVA (0.62 versus 0.50 ml/cmH2O/kg, p = 0.005).
