Abstract

Objective: To evaluate the effectiveness of Nasal Continuous Positive Airway Pressure (NCPAP) via Benveniste valve in the treatment of pediatric acute respiratory failure at the Respiratory Center of Vietnam National Children's Hospital. Subjects and methods: This prospective descriptive study included 31 patients treated for acute respiratory failure by NCPAP at the Respiratory Center of Vietnam Natinonal Children's Hospital from 7/2020 to 6/2021. Results: The success rate of NCPAP was 61.3%, the mean time was 5.23 days. After 6 hours, the arterial blood gas was significantly improved: PaO₂ increased from 77.98 mmHg to 110.33 mmHg, SaO₂ increased from 87.67% to 95.95%, PaCO₂ decreased from 59.02 mmHg to 54.48 mmHg, pH increased from 7.32 to 7.37. The rate of children with tachypnea decreased from 96.8% to 45.2%, the rate of chest indrawing decreased from 90.3% to 58.1%, the rate of cyanosis fell from 96.8% to 35.5%, and the rate of irritability or lethargy dropped from 96.8% to 22.6%. Conclusion: Nasal Continuous Positive Airway Pressure via Benveniste valve is effective in improving arterial blood gas as well as clinical signs of pediatric acute respiratory failure at the time after 6 hours.
