Effect of high flow humidification oxygen therapy on pulmonary infection in bedridden elderly patients with cerebral infarction
Abstract：Objective To analyze the effect of high flow humidification oxygen therapy on pulmonary infection in elderly patients with cerebral infarction and the effect on oxygen saturation and pneumonia in patients with cerebral infarction. Methods A retrospective study was conducted on 70 elderly patients with pulmonary infarction who were hospitalized in geriatrics department of Affiliated Hospital of Chengde Medical College from May 2015 to January 2017. The patients were divided into control group and experimental group according to different oxygen feeding methods.The control group was treated with traditional nasal catheter oxygen mask,the experimental group were treated with high respiratory flow humidified oxygen. The heart rate,respiratory frequency,blood pressure,blood gas index change,change the expectoration ability of patients,the hospital infection rate and patients,the incidence of drug-resistant bacteria,antibiotic use time were observed in the two groups. Results There was no difference of blood pressure before and after treatment in two groups(P> 0.05). 1H,4H two groups,24h heart rate,respiratory rate,PaO2,PaCO2,SaO2,PH and oxygen index levels were improved dramatically after treatment than before treatment in two groups(P< 0.05),and these treatment index were better in experimental group than in control group after treatment(P < 0.05). Two groups of patients after treatment of sputum viscosity grade was improved too after treatment in the two groups(P < 0.05),and the sputum characters was better in experimental group than control group after treatment(P< 0.05). The rate of internal infection and the incidence of drug-resistant bacteria in experimental group were lower than those of the control group,and the time of antibiotics use was shorter in experimental group than that in control group(P<0.05).Conclusion High flow humidification oxygen therapy can improve the blood gas index and respiratory function of pulmonary infection in elderly patients with bedridden cerebral infarction,and improve the comfort of patients,and reduce the incidence of nosocomial infection and the incidence of drug-resistant bacteria.
