Abstract:
Objective To investigate the effects of precautionary high-flow oxygen therapy on preventing hypoxemia in patients with Stanford type A aortic dissection after intubation.Methods Totally 90 hospitalized patients with Stanford type A aortic dissection in our hospital were enrolled in this study.Forty-five patients were recruited in the control group from January to April 2017,and the common mask-type nebulizer was used for oxygen inhalation.From May to October in 2017,45 patients were recruited in the experimental group.The parameters of highflow oxygen therapy in the experimental group were set as oxygen concentration (FiO2) 40％～60％,oxygen flow rate 35～60 L/min.Then after 72h's therapy,normal mask oxygen therapy was provided as replacement therapy.Results Oxygenation index and oxygen partial pressure were increased in the experimental group than those in the control group,the rate of respiration and carbon dioxide partial pressure were decreased than those in the control group,and the differences were statistically significant(P＜0.05).The scores of oral nasal dryness symptom and sore throat symptom in the experimental group were lower than those in the control group in 24 h,48 h,72 h during therapy,and the differences were statistically significant (P＜0.05).The incidence of hypoxemia and the incidence of secondary intubation were lower in the experimental group than those in the control group(P＜0.05).Conclusion Precautionary high-flow oxygen therapy for patients with Stanford type A aortic dissection can increase PaO2/FiO2,PaO2,reduce PaCO2,respiratory rate,reduce respiratory symptoms,reduce the incidence of hypoxemia,and secondary intubation.
