Influence of endotracheal intubation type on aspiration after extubation in patients with traumatic brain injury
Objective To determine whether the diagnosis of accidental suction after extraction of a TBI patient is related to a changea-ble risk factor,the trachea intubation model.Methods From January 2021 to January 2023,150 experimental subjects were selected and di-vided into three groups A,B and C according to the endotracheal intubation model within 24 hours of intubation and registered,and within 6 hours after extubation,all patients underwent fiberoptic bronchoscopy,and the quantitative values of oral and tracheal specimens α-amylase and pepsin A were used as aspiration biological samples.Results A total of 150 patients with 50 patients in each group were included.There was no significant difference in clinical data between the three groups(P＞0.05).The α-amylase level and pepsin A concentration of the pa-tients were statistically significant in group A＜group B＜group C after 6 hours of extubation(P＜0.05),and the pepsin A≤of all patients in this study was 200 ng/mL and the α-amylase≤was 3 314 UI/L.The positive rates of flexible bronchoscopy and biomarkers were both in group A＜group B＜group C,and the difference was statistically significant(P＜0.05).The positive rate of fiber bronchoscopy≤the positive rate of biological specimens,and the positive rate of pepsin in each group＞α-amylase.The difference was statistically significant(P＜0.05).Conclusion The use of a larger endotracheal tube for ETT in patients with head injury is associated with the risk of aspiration af-ter extubation.The use of a smaller model of endotracheal tube reduces the risk of aspiration after extubation.
