Overview
Brief Summary
Guidelines for noninvasive ventilation (NIV) recommend continuous positive airway pressure in patients with thoracic trauma who remain hypoxic . However, no any suggestion was applied for high flow nasal cannula (HFNC). Therefore, Our aim was to determine whether HFNC reduces intubation in severe trauma-related hypoxemia.
Detailed Description
This would be a three-center randomized clinical trial of a level I trauma hospital. Inclusion criteria were patients with Arterial oxygen level (Pao2/)fraction of inspired oxygen inspired oxygen fraction(Fio2)\<300 while receiving oxygen by high-flow mask within the first 72 h after thoracic trauma. Patients were randomized to remain on high-flow oxygen mask/ noninvasive ventilation or to receive HFNC. The interface was selected based on the associated injuries.

Eligibility Criteria
Inclusion Criteria
- •Patients who have the following condition within 72 hours of chest trauma despite receiving standard nasal cannula oxygen therapy \[≥10 L/min\], are eligible for inclusion.
- •severe hypoxemic respiratory failure \[Arterial partial pressure of oxygen (PaO2)/fraction of inspired oxygen fraction(FiO2) \<300 mmHg\]
- •with a respiratory rate \>25 breaths/minute and difficulty breathing, or respiratory distress
- •PaCO2 of 45 mmHg or higher (if the patient requires emergency surgery with endotracheal intubation and mechanical ventilation, the time of inclusion will be the start of the post-extubation period. (Note: For patients who receive emergency trauma surgery with endotracheal intubation and mechanical ventilation, the time of inclusion assessment will be 72 hours after extubation.)
Exclusion Criteria
- •Patients with a Glasgow Coma Scale less than 8 or severe brain injury.
- •Patients with any contraindications to non-invasive ventilation, including acute gastrointestinal bleeding, upper airway obstruction, or hemodynamic instability.
- •Facial trauma involving skull base fractures, facial bone fractures, or orbital floor fractures.
- •Severe injuries involving the nasal sinuses.
- •Patients with cervical spine injuries.
- •Patients with increased intracranial pressure.
- •Patients with facial, nasal, or airway structural abnormalities or surgery that prevents the use of appropriate nasal cannula.
- •Patients after upper airway surgery.
- •Patients who are unable to clearly express their willingness to sign informed consent.
Outcomes
Primary Outcomes
Rate of event of intubation or pneumonia
Time Frame: 30 days after randomization
Intubation criteria included a respiratory rate of \>40 breaths per minute, signs of increased breathing effort, SpO2 of \<90% despite high fraction of inspired oxygen inspired oxygen fraction or acidosis with the quantitative measure of the acidity or basicity of aqueous or other liquid solutions (pH scale) of \<7.35, occurrence of hemodynamic instability or deterioration of neurologic status.
Secondary Outcomes
- P/F ratio(48 hrs after randomization)
- pneumonia rate /tracheostomy rate(30 days after randomization)
