NCT04559334

Brief Summary

In this research study we want to learn more about a study drug, tetrasodium sodium EDTA (Kitelock™) for maintaining the patency (blood flow) through a central venous catheter. Catheter occlusions such as blood clots have been shown to increase the risk of central line-associated bloodstream infection (CLABSI). This treatment consists of instilling a daily a dose of a solution , similar to heparin or saline lock flushes, into the catheter when it is not in use. The aim is to prevent CLABSI without increasing complications such as catheter breakage.

Study Arms (1)

OTHER

All participants will receive Tetrasodium EDTA Catheter Lock Solution (KiteLock™ 4% Sterile Catheter Lock Solution)

Device: Tetrasodium EDTA Catheter Lock Solution

Interventions

KiteLock™ 4% Sterile Catheter Lock Solution is a single use, clear, colorless and sterile solution. It is free of preservatives, alcohol and latex and is non-pyrogenic. KiteLock™ 4% is an aqueous solution containing a mixture of edetate tetrasodium and edetate trisodium. The solution composition is equivalent to 28 mg/mL edetate. EDTA is a known chelator. This means it has an affinity for metals and elements such as calcium. As a primary mechanism of action, it acts as a space occupying solution to prevent blood from entering the tip of the catheter when the catheter is not in use. As a secondary mechanism of action, it acts as an in vitro anticoagulant. This dual action decreases the risk of clot formation, consequently thrombolytic occlusions and by extension decreases the risk of CLABSI.

Also known as: KiteLock™ 4% Sterile Catheter Lock Solution
