Respiratory physiological changes post initiation of neurally adjusted ventilatory assist in preterm infants with evolving or established bronchopulmonary dysplasia.

ABSTRACT: To assess respiratory changes after neurally adjusted ventilatory assist (NAVA) initiation in preterm infants with evolving or established bronchopulmonary dysplasia (BPD). Premature infants born less than 32 weeks gestation with evolving or established BPD initiated on invasive or non-invasive (NIV) NAVA were included. Respiratory data: PCO_₂ and SpO₂/FiO₂ (S/F) ratio before and at 4, 24, 48 h post-NAVA initiation were collected. Eighty-eight infants, median GA 25.1 (range 22.7-30.3) weeks, with 191 NAVA episodes were included. Infants born < 32 weeks with evolving and established BPD showed improvements in PCO_₂ and S/F ratio 48 h post-NAVA compared to prior: 7.6 (4.5-11.8) versus 8.1 (4.7-13.1) kPa; p < 0.001 and 285 (118-471) versus 276 (103-471); p = 0.013, respect
