Clinical Trial Summary

This is a randomized controlled trial (RCT) to evaluate the influence of two flow rates (6 liter/min versus 3 liter/min) of Heated-Humidified High-Flow-Nasal-Cannula (HHHFNC) on rates of extubation failure in mechanically ventilated preterm infants.


Description:

HHHFNC has been proposed as an alternative to nasal continuous positive airway pressure (nCPAP) in neonatal intensive care units (NICUs) for preventing extubation failure. In a recent international survey on periextubation practices in extremely preterm infants, nCPAP was the most common type of respiratory support used (84%) followed by nasal intermittent positive pressure ventilation (55%) and HHHFNC (33%). Moreover, HHHFNC appears to have efficacy and safety similar to those of nCPAP when applied immediately post-extubation to prevent extubation failure in preterm infants. and resulted in significantly less nasal trauma in the first 7 days post-extubation than nCPAP. However, the best flow rates of HHHFNC to prevent extubation failure remains to be known.

This RCT aims to compare the efficacy and safety of postextubation respiratory support via HHHFNC at two different flow rates (6 L/min. versus 3 L/min) regarding successful extubation after a period of endotracheal positive pressure ventilation. We hypothesized that postextubation respiratory support via HHHFNC at a flow rate of 6 L/min. will result in a greater proportion of preterm infants being successfully extubated after a period of endotracheal positive pressure ventilation compared with HHHFNC at a flow rate of 3 L/min.

Intervention

Device:
HHHFNC 6 liter minute
Infants allocated to HHHFNC at 6 L/min. will be extubated to a HHHFNC flow of 6 L/min. Eligible infants will be enrolled while receiving mechanical ventilation. The timing of extubation will be determined by the clinical team and all infants will start caffeine prior to extubation.
HHHFNC 3 liters/min
Infants allocated to HHHFNC at 3 L/min. will be extubated to a HHHFNC flow of 3 L/min. Eligible infants will be enrolled while receiving mechanical ventilation. The timing of extubation will be determined by the clinical team and all infants will start caffeine prior to extubation.

Outcome

Type Measure Description Time frame Safety issue
Primary Extubation failure Extubation failure criteria will be defined as follows:
Apnea (respiratory pause >20 seconds), more than 6 episodes requiring physical stimulation in 6 hours or 1 requiring intermittent positive pressure ventilation.
Respiratory acidosis with pH <7.25 and Peripheral arterial oxygen saturation (PaCO2) >65 mmHg.
( >15% sustained increase in FiO2 from extubation. 4. Cardiovascular collapse (heart rate <60 beats per minute or shock. 5. Persistent marked/severe retractions. Extubation failure will be deemed to occur if any single criterion was met in any one of the 7 days after extubation. The decision to reintubate an infant and mechanical ventilation variables and subsequent extubation attempts after reintubation will be managed at the discretion of the clinical team.
