HFNC and NCPAP in Extremely Preterm Infants

August 24, 2018 updated by: Guilherme Sant'Anna, MD

Comparisons of the Dynamic of the Cardiorespiratory System Behavior of Extreme Preterm Infants Receiving Nasal CPAP or High Flow Nasal Cannula During the Immediate Post-extubation Period

To avoid or decrease the rate of complications in preterm infants after disconnection from a mechanical ventilation (extubation), non-invasive respiratory support is routinely used. While infants are most commonly extubated to nasal continuous positive airway pressure (NCPAP), high flow nasal cannula (HFNC) has emerged as an attractive alternative. However, research regarding the safety and efficacy of HFNC in the most extreme preterm infants is limited. Therefore, we hypothesize that immediately after extubation, measures of heart rate and respiratory behavior may be useful to investigate for any differences between HFNC and NCPAP.

Detailed Description

Infants will be studied 30 min after extubation on both modes of support, provided in a random order. A transition period of 15 min between modes will be given. For each mode, recordings will be performed for 40 minutes. Analysis of these recordings will be done off line.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: HFNC/NCPAP
HFNC will be provided for 45 minutes followed by NCPAP for 45 minutes. Cardiorespiratory signals including electrocardiogram (ECG), respiratory inductive plethysmography (RIP), oxygen saturation (SpO2) and Pulse rate will be recorded continuously during the interventions and analyzed offline.
HFNC therapy will be delivered with a system that provides heated, humidified high flow of gas through a tube that maintains the temperature and humidification. This intervention will involve the delivery of gas (air/oxygen) at a high flow rate, using an adequate nasal cannulae size and a cannula/nostril diameter ratio between 0.5-0.8.
NCPAP will be provided as either bubble CPAP or through a ventilator, and will deliver a regulated pressure of gas (air/oxygen) to the patient through infant binasal prongs as interface. Nasal prong sizes will be chosen according to manufacturer recommendations.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Differences on Heart Rate Variability in extremely preterm infants receiving HFNC and NCPAP
Time Frame: Immediate post-extubation period
Cardiac signals from the electrocardiogram will be continuously measured throughout the recordings. Analysis of these signals will be performed offline to calculate heart rate variability using linear and nonlinear methods.
Immediate post-extubation period
Differences on Respiratory Variability in extremely preterm infants receiving HFNC and NCPAP
Time Frame: Immediate post-extubation period
Respiratory variability will be calculated by using analysis of respiratory inductive pletysmography signals from the recordings during HFNC and NCPAP. Desaturation events will also be calculated from these recordings.
