RESUMEN

This paper reviewed three aspects of risk factors of catheter-related thrombosis in critically ill children with central venous access devices, including the child's own factors, catheter-related factors and external factors. It summarized the main research advances of preventive measures such as the strengthen assessment of pre-catheterization, drug and mechanical prevention of thrombosis, control of catheter-related other complications, thrombus screening routinely, risk assessment model is used. It is to provide experience for early clinical identification and formulation of preventive measures, so as to reduce the occurrence of catheter-related thrombosis in critically ill children and promote the central venous access device used safely in PICU.

RESUMEN

Objective Doppler ultrasonography was used to screen the incidence of central venous catheter (CVC) thrombosis in severe patients to observe the incidences of catheter-related thrombosis (CRT) at subclavian (SC) and internal jugular (IJ) venous insertion sites, and to analyze the factors affecting the thrombosis. Methods One hundred and twenty three adult patients with IJ or SC CVC admitted to the Department of Intensive Care Unit (ICU) of Zhongnan Hospital of Wuhan University from May to December 2015 were enrolled to be the research objects, they were divided into an IJCVC group (35 cases) and a SCCVC group (88 cases) according to different catheterization sites; they were divided into an operation group (85 cases) and a non-operation group (38 cases) according to whether operation was performed or not; and they were also divided into an anticoagulation group (25 cases) and a non-anticoagulation group (98 cases) according to whether anticoagulation therapy was used or not. Doppler ultrasonography was performed every day to observe the incidences of CRT during ICU stay. Results One hundred and twenty-three patients were included in this study. CRT was detected in 11 (8.9%) patients, with an incidence of 22.1 per 1 000 catheter-days. All the 11 cases with CRT were presented within 3 days after the insertion, with 9 cases (81.8%) on the first day and 2 cases (18.2%) on the third day. The incidence of CRT in SCCVC group was significantly lower than that in IJCVC group [5.7% (5/88) vs. 17.1% (6/35), P < 0.05], with the rates of 12.6 and 59.4 per 1 000 catheter-days, respectively. There were no statistical significant differences in the incidences of CRT between operation group and non-operation group [11.8% (10/85) vs. 2.6% (1/38)], and between anticoagulation group and non-anticoagulation group [8.0% (1/25) vs. 9.2% (2/98), both P > 0.05]. Conclusions The incidence of CRT at IJCVC site is estimated to be 3-times higher than that at SCCVC site, anticoagulants or surgical operation may have impacts on the incidence of CRT, although there were no statistically significant differences. The CRT usually occurs within 3 days after the catheter insertion. Frequent bedside ultrasonography in the first 3 days after catheterization can confirm the diagnosis and guide clinical treatment.

RESUMEN

Although indwelling central venous catheters guarantee a reliable vascular access, and are essential for the management of children undergoing anticancer chemotherapy or stem cell transplantation, these catheters may cause serious mechanical, infectious and thrombotic complications. Central venous catheter-related thrombosis is one of the most important complications that may interfere with the course of treatment. A number of regimens utilizing urokinase have been used but the optimum management of this common problem remains undetermined. We report an 8 year-old boy, who had catheter-related atrial thrombus treated successfully with urokinase. A short course treatment with the use of low-dose urokinase was feasible for the thrombolysis of catheter-related right atrial thrombus in this boy diagnosed with neuroblastoma and undergoing high-dose chemotherapy with autologous peripheral blood stem cell rescue. This treatment was not associated with bleeding.
