Abstract
Objective: To explore the observation and nursing of patients with acute mass asphyxia poisoning with pulmonary bullae treated by nasal high-flow humidification and oxygen therapy. Methods: Review and summarize the data of 5 patients with acute mass asphyxial gas poisoning with pulmonary vesicles who were admitted to the department of toxicology of this hospital in June 2019 and received nasal high-flow humidification and oxygen therapy. The oxygenation index, airway humidification and prognosis were observed. Results: All the 5 patients were successfully transferred to nasal catheter for oxygen inhalation after nasal high-flow humidification and orygen therapy without intubation. When discharged from the hospital without oxygen, pH: 7.36-7.42, PO(2):82-106 mmHg, PCO(2):32-39 mmHg. All the white blood cells and myocardial enzymes were normal, and there was no brain injury, perinasal skin damage and abdominal distension. Conclusion: Nasal high-flow humidification and oxygen therapy can effectively improve the efficacy of oxygen therapy for patients with acute mass asphyxial gas poisoning with pulmonary vacuoles.
