Đánh giá bước đầu hiệu quả cải thiện oxy hóa máu của phương pháp thông khí cơ học tư thế nằm sấp ở bệnh nhân suy hô hấp cấp tiến triển

To initially evaluate the effectiveness of improving blood oxygenation of prone position mechanical ventilation in patients with acute respiratory distress syndrome (ARDS) at the Intensive Care Unit, 108 Military Central Hospital. Subject and method: 18 patients with moderate or severe ARDS (PaO2/FiO2 < 150mmHg with PEEP ≥ 5cmH2O, FiO2 ≥ 60%) were treated at the Intensive Care Unit, 108 Military Central Hospital from February 2020 to September 2021 were indicated prone position mechanical ventilation. Result: The percentage of patients with improved blood oxygen was 83.3%. SpO2, PaO2 improved significantly after prone positioning for 1 hour and during the time of prone positioning. The PaO2/FiO2 ratio increased immediately after the patient was prone positioning for 1 hour and continued to improve in the following hours. When patients returned to the supine position for 4 hours, the PaO2/FiO2 decreased compared to the prone position but was still higher than before the prone position, with p<0.001. Conclusion: The prone position mechanical ventilation had improved blood oxygenation in patients with ARDS.
