Abstract
Objective To explore how the different intervention measures affect the outcome of central venous catheter-related thrombosis (CRT) in children. Methods A retrospective analysis was carried out to collect the clinical data of patients with CRT from the nursing management system of the Children's Hospital Affiliated to Zhejiang University School of Medicine which reported by each nursing unit from January 1,2015 to December 31,2015. Results Totally 108 cases were included (72 boys and 36 girls), median age of 24.5 months (ranged from 1 month to 14 years old). Nearly 42.59% (46/108) patients suffered from neurological diseases. Nearly 55.56% (60/108) CRT was detected in the first week after catheterization. Once CRT conformed, there were four kinds clinical intervention options applied. Intervention 1: thrombolytic therapy with urokinase combined anticoagulation with nadroparin calcium. Intervention 2: anticoagulant therapy only. Intervention 3: thrombolytic therapy alone. Intervention 4: no medications. The differences of effective between the four kinds of intervention were statistically significant (χ2= 13.380, P= 0.004). The single-factor regression analysis was done to each relevant factor. Finally the multivariate regression analysis showed four factors had impacts upon the results. The factors were as follows: gender (OR= 10.400, 95% CI 1.879-57.563, P= 0.007); interval (OR= 1.107, 95% CI 1.035-1.184, P= 0.003), size of thrombus (OR= 1.562, 95% CI 1.033-2.362, P=0.035; Intervention 2 (OR= 11.757, 95% CI 2.254-61.327, P= 0.003), intervention 4 (OR= 35.397, 95% CI 3.493-358.760, P= 0.003). Conclusions The earlier and small size thrombus is more soluble. Thrombolytic therapy or combined anticoagulation is more effective. It is recommended that if no contraindications presents, thrombolytic combined with anticoagulant therapy should start early standardized treatment.
