Ethanol versus heparin locks for the prevention of central venous catheter-associated bloodstream infections: a randomized trial in adult haematology patients with Hickman devices.

The effectiveness of ethanol locks for prevention of central venous catheter (CVC)-associated bloodstream infection (CLABSI) in adult haematology patients has not been thoroughly evaluated. This study aimed to compare prospectively heparinized saline with 70% ethanol locks using 2 h dwell time in patients with tunnelled CVCs. In saline (N = 43) and ethanol (N = 42) groups, CLABSI rates were 6.0 [95% confidence interval (CI): 3.4-9.8] and 4.1 (95% CI: 1.9-7.7) per 1000 CVC days, respectively (P = 0.42). In the ethanol group, two exit-site infections and one tunnel/pocket infection were observed. Reduction in device-associated infection was not achieved with prophylactic 70% ethanol locks in patients with haematological malignancy and tunnelled CVCs.
