Nasal HFOV Versus Nasal SIPPV in Neonate Following Extubation: RCT Crossover Study

Summary

Mechanical ventilation was introduced to treat respiratory failure in preterm infants or sick neonates then improvements in survival (1,2). However, the complications from short or long term use of ventilation can result in unintended harm or burden (e.g., air leak syndrome, pneumonia, bronchopulmonary dysplasia, neurological injury, retinopathy of prematurity) (3,4). To reduce these risks, clinicians should aggressive extubated neonates as early as possible. Respiratory (focus on blood gas as well as partial pressure CO2 [pCO2]) or extubation (focus on clinical condition as well as reintubation) failure was worrisome in pediatrician and parents if the neonate was reintubated owing to complete recovery of lung disease or inadequate respiratory drive.

Non-invasive ventilation (NIV) was supported for primary respiratory support (initial mode before endotracheal intubation) or post-extubation. Nasal continuous positive airway pressure (nCPAP) was familiar to NIV mode in neonatal respiratory support. Nowadays, the new NIV modalities are nasal intermittent synchronized positive pressure ventilation (nSIPPV) and nasal high frequency oscillation (nHFO). To increase the likelihood of nCPAP success, other new modalities of NIV may be interesting. From theory, nSIPPV and nHFO combines peak inspiratory pressure (PIP) with synchrony and high-frequency oscillations without synchrony above CPAP, respectively. From meta-analysis, nSIPPV and nHFO were statistically significant superior than nCPAP both respiratory and extubation failure in neonate (5,6).

The aim of our study was to investigate the efficacy of nHFOV and nSIPPV for CO2 clearance and reintubation rate after extubated neonates. The investigators hypothesized that nHFOV mode would improve CO2 clearance better than nSIPPV mode.

Medical and Biotech [MESH] Definitions

Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).

Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances.

Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.

Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.

Ventilation of the middle ear in the treatment of secretory (serous) otitis media, usually by placement of tubes or grommets which pierce the tympanic membrane.
