ABSTRACT
Objective:To analyze the risk factors of modified midline catheter-related thrombosis and propose countermeasures.Methods:Retrospective analysis was used to divide patients admitted to the neurology department of Nanjing Drum Tower Hospital from February 2018 to July 2020 into thrombotic group (9 cases) and nonthrombotic group (117 cases). Univariate analysis and binary Logistic regression were used to analyze the risk factors for catheter-related thrombosis.Results:The incidence of thrombosis was 7.14% (9/126) in patients with modified midline catheters. Univariate analysis showed that the occurrence of catheter-related thrombosis in patients was related to the primary type ( χ2 value was 6.331, P<0.05) and catheter pretreatment ( χ2 value was 4.016, P<0.05). Multivariate analysis showed that there was no significant difference between the primary disease type and the catheter pretreatment method ( P>0.05). Conclusions:The incidence of thrombus in patients with encephalitis and pretreated catheter with normal saline is high, preventive care should be taken before the occurrence of thrombus, and thrombolytic therapy should be taken as soon as possible after the occurrence of thrombus.
