Value of corrected carotid flow time in predicting hypotension after tracheal intubation in emergency trauma patients
Objective To investigate the value of carotid corrected flow time(FTc)in predicting hypotension after tracheal intubation in e-mergency trauma patients.Methods A total of 110 emergency trauma patients admitted to the emergency department of our hospital from January 2021 to December 2022 were selected,among which 5 patients withdrew from the study due to hospital transfer or death,and 105 patients were finally included.According to whether hypotension occurred after intubation,they were divided into the hypotensive group(35 patients)and the non-hypoten-sive group(70 patients),all of which were examined by ultrasound before anesthesia.Carotid FTc was observed and the basic clinical data were statis-tically analyzed.The risk factors of hypotension after endotracheal intubation in emergency trauma patients and the predictive value of endotracheal intubation hypotension in carotid FTc emergency trauma patients were analyzed by comparing the changes of hemodynamic indexes between the two groups.Results Univariate analysis showed that the occurrence of hypotension after endotracheal intubation in emergency trauma patients was mainly related to age,mean arterial pressure(MAP)before endotracheal intubation,arterial oxygen saturation,acute physiological and chronic health score(APACHEⅡ)and shock index(SI)(P＜0.05).Compared with non-hypotensive group,the expression levels of heart rate(HR),diastolic blood pressure(DBP),systolic blood pressure(SBP)and FTc in hypotensive group were increased(P＜0.05).Hypotension after endotracheal intubation in e-mergency trauma patients was used as the dependent variable,and variables with P＜0.05 in univariate analysis were selected as independent vari-ables.The results of multivariate Logistic regression analysis showed that,age,arterial oxygen saturation,MAP before intubation and APACHE Ⅱscore were the main risk factors for hypotension after endotracheal intubation in emergency trauma patients(P＜0.05).Carotid FTc had high clinical value in predicting hypotension after tracheal intubation in emergency trauma patients(P=0.001).Conclusion To observe the changes of hemody-namic indexes after endotracheal intubation in emergency trauma patients,carotid FTc can effectively improve the value of predicting hypotension after endotracheal intubation in emergency trauma patients.
