Analysis of factors affecting the success rate of deep venous catheterization in emergency department / 中国实用护理杂志

ABSTRACT

Objective:To explore the factors affecting the success rate of deep venous catheterization in emergency department patients.Methods:A total of 578 patients who needed deep venous catheterization in the emergency department of the Third Hospital of Hebei Medical University from December 2015 to June 2019 were selected as the research subjects. Univariate analysis and Logistic regression analysis were performed to construct the model, and receiver operating characteristic curve was used to evaluate the diagnostic efficacy.Results:Among the 578 samples, 467 (80.8%) succeeded and 111 (19.2%) failed. The results of univariate analysis showed that six factors including gender, history of deep vein insertion, catheter type, operator length of service, insertion route, and blood pressure were related to the success rate of catheterization ( χ2 value was 10.231-179.665, P<0.05). Logistic regression analysis showed that these six factors were independent predictors of the success rate of deep vein catheterization ( OR value was 1.542-8.467, P<0.05). Based on this, the model was established and the area under the receiver operating characteristic curve of the model was 0.954. Conclusions:There are many factors influencing the success rate of deep venous catheterization in the emergency department. The technical level of the operator should be improved, and the appropriate catheter type and insertion route should be selected to improve the success rate of the catheterization.
