High Flow Nasal Oxygenation Versus Non-invasive Ventilation for Patients With Blunt Chest Trauma
A study testing high flow oxygenation in people with Chest Trauma, run by Huda Fahmy Mahmoud, PhD at 1 site in Egypt.
Trial summary
Chest trauma remains an issue for health services for both severe and apparently mild trauma management. Severe chest trauma is associated with high mortality and is liable for 25% of mortality in multiple traumas. Read more about this study

About this study
Official title: High Flow Nasal Oxygenation Versus Non-invasive Ventilation for Patients With Blunt Chest Trauma: A Comparative Study
Chest trauma remains an issue for health services for both severe and apparently mild trauma management. Severe chest trauma is associated with high mortality and is liable for 25% of mortality in multiple traumas. Moreover, mild trauma is also associated with significant morbidity, especially in patients with preexisting conditions. Thus, whatever the severity, a fast-acting strategy must be organized. In order to improve the prognosis of patients with severe chest trauma, early and continuous application of non-invasive mechanical ventilation (NIV) can indeed reduce the need for intubation and shorten intensive care unit length-of-stay. Among different mechanisms, the early use of positive end-expiratory pressure after chest trauma, when feasible, seems mandatory to optimize oxygenation and improve clinical outcomes. Indeed, interventions aimed at preventing ARDS after chest trauma carry the greatest potential to reduce the substantial morbidity, mortality, and resource utilization associated with this syndrome.
Read the detailed description
In the past years, High-flow nasal cannula oxygen (HFNC) has gained an important popularity among intensivest to manage patients with acute respiratory failure, filling a gap in the ventilatory support escalation between facemask oxygen and non-invasive or invasive mechanical ventilation. Interestingly, the use of HFNC was widely and rapidly adopted in ICUs.A unique feature of HFNC is its ability to comfortably deliver high flows of warmed humidified gas, 20-70 L min, with a FiO2 range of 0.21-1.0. Physiological responses to HFNC therapy include increases in airway pressure, end-expiratory lung volume (EELV), and oxygenation which are probably optimal with higher flows (60-70 L/min), while the effects on dead-space washout work of breathing, and respiratory rate may be obtained with intermediate flows (20-45 L/min).
Many studies have found that high flow nasal oxygen is much better tolerated by patients compared to non-invasive ventilation, which may improve compliance. Nevertheless, there is no clear consensus on the treatment outcomes (such as intubation rate, escalated respiratory support rate, and mortality) of high flow nasal oxygenation versus non-invasive ventilation for patients with traumatic chest injuries.

All patients will have FiO2 started at 0.4 and titrated to maintain oxygen saturation (SpO2) ≥ 95%.
| Study group | Role | What they receive |
|---|---|---|
| High flow nasal cannula (HFNC) group | Active comparator | All patients will have FiO2 started at 0.4 and titrated to maintain oxygen saturation (SpO2) ≥ 95%. The flow rate will be set at 60 L/min Receives: Procedure: high flow oxygenation |
| Continuous positive airway pressure (CPAP) group | Active comparator | All patients will have FiO2 started at 0.4 and titrated to maintain oxygen saturation (SpO2) ≥ 95%. Pressure will be set to 3 cm H2O for 5 minutes, then titrated according to patient comfort and tolerance, as well as clinical observation Receives: Procedure: high flow oxygenation |
What is being measured
The primary outcome is the main question the study is designed to answer.
the rate of intubation for mechanical ventilation
Intubation criteria included a respiratory rate of >40 breaths per minute, signs of increased breathing effort, SpO2 of <90% despite high FiO2 or acidosis with a pH of <7.35,occurrence of hemodynamic instability or deterioration of neurologic status.
Measured: 48 hours
Secondary outcomes (2)
the Comfort levels with the different modes of oxygen delivery
will be measured using a 5-point with Likert Scale (marked improvement, slight improvement, no change, slight deterioration, or marked deterioration)
Measured: 48 hours
the perceived effort of breathing with the different modes of oxygen delivery
will be measured using the modified Borg Scale (0-10)
Measured: 48 hours

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?
the rate of intubation for mechanical ventilation (time frame: 48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 20 Jan 2023; AzTrials last refreshed its copy on 6 Nov 2026.
