Abstract
- AIM: To verify the added value of respiratory function monitor (RFM) to assess ventilation and the heart rate (HR) changes during stabilization of preterm infants.METHODS: Preterm infants 100 bpm; T2 the delivery of the last PPV). For each inflation, PIP, PEEP, MAP, expired tidal volume/kg (Vte/kg), and mean dynamic compliance (Cdyn) were analyzed.RESULTS: PIP and MAP values were significantly higher at T1 (27.09 ± 5.37 and 17.47 ± 3.85 cmH2 O) and at T2 (24.7 ± 3.86 and 15.2 ± 3.78 cmH2 O) compared to T0 (24.05 ± 2.27 and 15.85 ± 2.77 cmH2 O). PEEP at T1 was significantly higher (6.27 ± 2.17 cmH2 O) compared to T2 (5.61 ± 1.50 cmH2 O). Vte/kg showed significantly lower T0 values (3.57 ± 2.14 ml/kg) compared to T1 (6.18 ± 2.51 ml/kg) and T2 (6.89 ± 2.40 ml/kg). There was a significant effect of time on Cdyn.CONCLUSIONS: A clear correspondence between HR rise and adequate Vte/kg during stabilization of very preterm infants was highlighted. RFM might be useful to tailor ventilation, following real-time changes of lung compliance.
