Abstract
Objectives: To investigate the incidence of central venous catheter-related thrombosis (CRT), risk factors, complication and convalescence in critically ill patients. Methods: This observational study comprised patients with central venous catheters (CVCs) from November 2009 to November 2010 in ICU of Saga University Hospital. We used ultrasonography to detect CRT. Results: The incidence of CRT was 107/205 cases of CVCs (52%) in 67/100 patients. The incidence of CRT at internal jugular vein was higher than the incidence at femoral vein (63% vs 28%, P < 0.001). Patients with CRT often complicated any infection in comparison with patients without CRT (67% vs 45%, P = 0.04). Rates of central line-associated bloodstream infection were higher among CVCs with CRT than CVCs without CRT (9% vs 1%, P = 0.008). Length of ICU stay for patients with CRT was prolonged in comparison with patients without CRT, whereas mortality rate was comparable between patients with CRT and patients without CRT. Conclusions: CRT occurred in 52% of 205 CVCs and might be related with infection.
