Effect of anti-microbial-coated central venous catheter on catheter-associated deep venous thrombosis / 临床麻醉学杂志

ABSTRACT

Objective To evaluate the effect of anti-microbia-l coated central venous catheter (CVC),compared with routine CVC,on catheter-associated deep venous thrombosis (CADVT). Methods A total of 1 359 patients,aged 26-82 years,ASA physical status Ⅰ-Ⅲ,undergoing internal jugular,axillary-subclavian,or femoral vein CVC catheterization during January to June of 2017,were retrospectively reviewed.The patients were divided into intoanti-microbial-coated CVC group (group A)and routine CVC group (group B).Gender,age,ASA class,pre-operative risk of thrombus (Caprini score),CVC site,surgical site,ultrasound-guided catheterization,and anticoagu-lation therapy,CADVT and the degree,as well as the other adverse events were recorded.Results A total of 938 patients were successfully matched.There were 323 (34.4%)articipants diagnosed with CADVT with bedside point-of-care ultrasound,in which 172 cases (36.7%)in group A and 151 (32.2%)in group B.There was no statistical significance of CADVT and the degree between the two groups.The subgroup analysis results indicated that the patients using anti-microbial-coated CVC with high risk of thrombus (Caprini score ≥ 5 points)(OR 1.34,95% C I 1.01-1.78),undergoing catheterization according to anatomical landmark (OR 1.69,95% C I 1.04-2.74),and not-receiving anticoagulation therapy (OR 1.39,95% C I 1.01-1.92)had an increased risk of CADVT compared with those using routine CVC.A significantly decreased incidence of catheter-associated infection in group A was observed compared with group B (0.9% vs 4.1%,P<0.05).Conclusion Anti-micro-bial-coated CVC does not increase the incidence of CADVT.
