Insights
Volume guarantee (VG) with high-frequency oscillatory ventilation (HFOV) improved outcomes for preterm infants with hypoxic respiratory failure (HRF). This approach reduced the combined risk of death or bronchopulmonary dysplasia and episodes of hypercarbia compared to HFOV alone.
Area of Science:
- Neonatal Medicine
- Pediatric Critical Care
- Respiratory Physiology
Background:
- Hypoxic respiratory failure (HRF) is a critical condition in preterm infants.
- Conventional mechanical ventilation (CMV) may be insufficient for severe HRF.
- High-frequency oscillatory ventilation (HFOV) is an alternative but can have limitations.
Purpose of the Study:
- To evaluate the impact of adding volume guarantee (VG) to HFOV.
- To compare HFOV with VG versus HFOV alone in preterm infants with HRF.
- To assess the effect on mortality, bronchopulmonary dysplasia (BPD), and hypercarbia.
Main Methods:
- A comparative study of 52 preterm infants with HRF.
- Infants were refractory to CMV.
- Group 1: HFOV alone (n=34) as rescue therapy.
- Group 2: HFOV combined with VG (n=18) as rescue therapy.
Main Results:
- HFOV with VG significantly reduced the combined outcome of death or BPD (p = 0.017).
- HFOV with VG also significantly decreased episodes of hypercarbia (p = 0.010).
- These benefits were observed compared to HFOV alone.
Conclusions:
- Combining HFOV with VG is beneficial for preterm infants with HRF.
- This strategy improves survival and reduces lung injury (BPD).
- VG-HFOV effectively manages hypercarbia in this vulnerable population.
Background:
The aim of this study was to assess the effect of volume guarantee (VG) on high-frequency oscillatory ventilation (HFOV) compared with HFOV alone in preterm infants with hypoxic respiratory failure (HRF).
Methods:
Fifty-two preterm infants with HRF refractory to conventional mechanical ventilation (CMV) were enrolled in this study. Between June 2012 and February 2016, HFOV alone was used as rescue therapy when CMV failed for 34 infants, whereas HFOV combined with VG was used as rescue therapy for the other 18 infants between March 2016 and December 2017.
Results:
HFOV combined with VG resulted in a reduction in the combined outcome of death or bronchopulmonary dysplasia (BPD) (p = 0.017) and also a reduction in episodes of hypercarbia (p = 0.010) compared with HFOV alone.
Conclusion:
In this study, the preterm infants with HRF ventilated using HFOV combined with VG had a reduced combined outcome of death or BPD and hypercarbia compared with those who received HFOV alone.
