NCT05987800

Brief Summary

This is a prospective, observational cohort study. For the study part on noninvasive neurally adjusted ventilatory assist (NIV-NAVA) the design is interventional. For all participants prospective data collection will be conducted by chart review and by downloading ventilatory data from the ventilator. A registration of respiratory severity score will be done by a caregiver during the weaning period. This consists of a visual assessment of the work of breathing every 2 hours. For participants on NIV-NAVA consenting to the interventional part of the study a titration procedure will be conducted, afterwards serial electrical impedance tomography and lung and diaphragm ultrasound measurements will be done.

Study Arms (1)

Preterm infants on non-invasive respiratory support

OTHER

All infants on non-invasive respiratory support will be studied. Only infants on less than 32 weeks of gestation at birth, will undergo an intervention.

Diagnostic Test: Titration procedureDiagnostic Test: Electrical impedance tomographyDiagnostic Test: Lung and diaphragm ultrasound

Interventions

Titration procedureDIAGNOSTIC_TEST

The NAVA level will be reduced to 0,5 cmH2O/microvolt (µV) for 3 minutes as a starting point. Limit peak pressure will be set to 35 cmH2O (the maxi-mum pressure that can be delivered to the patient is cut off at 30 cmH2O). Other ventilator settings will be left unchanged and are as clinically indicated. Starting from a NAVA level of 0,5 cmH20/µV the level will be increased by 0,5 cmH2O/µV every 3 minutes until reaching a maximum NAVA level of 2,5 cmH2O/µV.

Preterm infants on non-invasive respiratory support

This is a non-invasive technique consisting of the application of a non-adhesive single-use patient belt to monitor regional changes in lung aeration at the bedside.

Preterm infants on non-invasive respiratory support

Lung ultrasound is a non-invasive technique used to diagnose lung pathology and to monitor lung condition. This technique is part of the standard of care for preterm infants in our neonatal unit. Lung ultrasound scores are calculated at each time an ultrasound is performed. Ultrasound of the diaphragm consists of a short additional measurement of diaphragm thickness and thickening fraction and will be done at the same time of the lung ultrasound following a standardized procedure.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Preterm infants (\< 37 weeks GA) supported with non-invasive respiratory support for at least 24 hours. Non-invasive respiratory support can consist of non-invasive NAVA, nasal continuous positive airway pressure (nCPAP) or high flow nasal canula (flow \> 2 liters/min).The support can be given as primary respiratory support or as respiratory support after weaning from invasive ventilation (= after extubation).
  • Infants can only be enrolled after written and signed informed consent by the parents.

You may not qualify if:

  • Infant born after a gestational age of 37 weeks or more.
  • Infants with major congenital malformations or chromosomal abnormalities (eg trisomy 18, congenital diaphragmatic hernia…)
