Background:
Patients with pulmonary contusion (PC) following blunt chest trauma are at risk of developing acute lung injury. High-flow nasal cannula (HFNC) is an established method for managing hypoxic respiratory failure (HRF).
Aim:
This study aims to evaluate the efficacy of oxygen therapy delivered through HFNC vs venturi mask (VM) in patients with hypoxia following traumatic lung contusion, to reduce the need for intubation and ventilation.
Materials And Methods:
This is an open-label randomized controlled trial conducted on 120 patients with HRF following traumatic PC and a PaO2/FiO2 of 100-200 mm Hg. Patients were divided into two groups: Group A (60 patients) received oxygen therapy through HFNC, while group B (60 patients) received oxygen therapy through VM.
Results:
High-flow nasal cannula significantly improved pulmonary oxygenation as early as 1 hour after randomization and the after with statistically significant improvement of PaO2/FiO2 over time (p < 0.001). However, it was associated with a nonsignificant reduction in the rate of intubation and mechanical ventilation (p = 0.255) and a nonsignificant reduction in the mortality rate (p = 0.491). The extent of PC was found to be an independent predictor of mortality (p = 0.589) and length of hospital stay (p = 0.581) by multivariate analysis.
Conclusion:
The early use of HFNC is associated with a significant improvement in pulmonary oxygenation. We suggest that HFNC can be used as a first-line oxygen therapy in hypoxic patients with lung contusion following blunt chest trauma.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
