ABSTRACT
OBJECTIVE:
To determine if the electrical activity of the diaphragm, as measure of neural respiratory drive and breathing effort, changes over time in preterm infants transitioned from nasal continuous positive airway pressure (nCPAP) to high flow nasal cannula (HFNC).DESIGN:
Prospective observational study.SETTING:
Neonatal intensive care unit. PATIENTS Stable preterm infants transitioned from nCPAP to HFNC using a 11 pressure to flow ratio.INTERVENTIONS:
The electrical activity of the diaphragm was measured by transcutaneous electromyography (dEMG) from 30â min before until 3â hours after the transition. MAIN OUTCOMEMEASURES:
At eight time points after the transition to HFNC, diaphragmatic activity was compared with the baseline on nCPAP. Percentage change in amplitudedEMG, peakdEMG and tonicdEMG were calculated. Furthermore, changes in respiratory rate, heart rate and fraction of inspired oxygen (FiO2) were analysed.RESULTS:
Thirty-two preterm infants (mean gestational age 28.1±2.2â weeks, mean birth weight 1118±368â g) were included. Compared with nCPAP, the electrical activity of the diaphragm did not change during the first 3â hours on HFNC (median (IQR) change in amplitudedEMG at t=180â min 2.81% (-21.51-14.10)). The respiratory rate, heart rate and FiO2 remained stable during the 3-hour measurement.CONCLUSIONS:
Neural respiratory drive and breathing effort assessed by electrical activity of the diaphragm is similar in the first 3â hours after transitioning stable preterm infants from nCPAP to HFNC with a 11 pressure-to-flow ratio.Palabras clave
