About this study
Official title: Comparative Study of the Effects of Continuous Positive Airway Pressure and Heated, Humidified High Flow Nasal Cannula on Diaphragmatic Dimensions in Preterm Infants
This is a prospective, randomized crossover study to recognize the effects of nasal continuous positive airway pressure (CPAP) versus heated humidified high flow nasal cannula (HHHFNC) on diaphragmatic dimensions and excursion (evaluated by ultrasonography) in preterm infants.
Read the detailed description
Preterm infants will be recruited consecutively from NICU of Mansoura University Children's Hospital. They will be randomized in two groups; one group will start on nasal CPAP (Fisher \& Paykel Healthcare, Auckland, New Z ealand) (Pressure 5 cmH2O) for 60 minutes and then will be switched to HHHFNC (Fisher \& Paykel Healthcare, Auckland, New Z ealand) (flow of 4 l/m) for another 60 minutes. The other group will start on HHHFNC and then switched to nasal CPAP.
After the 2 h study period (2×60 minutes epochs) further respiratory support will be at the discretion of the clinical team.
Ultrasonographic assessment of diaphragmatic dimensions and excursion will be analyzed in different respiratory cycles and the average of 3 cycles will be calculated at the end of the 60 minutes periods on nasal CPAP and HHHFNC.

What is being measured
The primary outcome is the main question the study is designed to answer.
Diaphragmatic dimensions (inspiratory diaphragmatic thickness, expiratory diaphragmatic thickness and delta diaphragmatic thickness)
Ultrasonographic assessment of (inspiratory diaphragmatic thickness, expiratory diaphragmatic thickness and delta diaphragmatic thickness will be assessed at the end of each 60 minutes epoch on nasal CPAP. Diaphragm thickness will be measured as the perpendicular distance between the pleural and peritoneal reflections. All measurements will be performed during quiet breathing. Several respiratory cycles will be recorded, and measurements will be averaged from at least three different cycles.
Measured: at the end of each 60 minutes epoch on nasal CPAP
Right and left diaphragmatic excursion
Ultrasonographic assessment of right and left diaphragmatic excursion will be assessed at the end of each 60 minutes epoch on nasal CPAP. The displacements of the liver and spleen will be monitored in real-time. Using M-mode ultrasonography, with the probe fixed on the chest wall during respiration, ultrasonographic image of will be frozen and a mark for measurement will be placed on the image at the location of the most caudal margin of the liver or spleen at the end of expiration, and a second mark will be placed on the new location of the most caudal margin of the liver or spleen at the end of inspiration. The distance between the two marks will be then measured and defined as the displacement of the liver or the spleen (right or left diaphragmatic excursion). Several respiratory cycles will be recorded, and measurements will be averaged from at least three different cycles.

Questions about this trial
What is this clinical trial studying?
A study testing CPAP first (Fisher & Paykel Healthcare) and HHHFNC first (Fisher & Paykel Healthcare) in people with Respirtory Distress, run by Mansoura University Children Hospital at 2 sites in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diaphragmatic dimensions (inspiratory diaphragmatic thickness, expiratory diaphragmatic thickness and delta diaphragmatic thickness) (time frame: at the end of each 60 minutes epoch on nasal CPAP). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02421328, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2017; AzTrials last refreshed its copy on 8 Nov 2026.
