Experience with double lumen right atrial catheters.

A double lumen right atrial catheter was placed in 57 allogeneic marrow transplant recipients, and its use was compared to a concurrent series of 63 patients receiving the large-bore single lumen catheter. Ten double lumen catheter recipients developed septicemia, while neutropenic with granulocyte counts less than 100 per cubic centimeter, and three had their catheters removed for persistent septicemia. Seventeen single lumen catheter recipients developed septicemia while granulocytopenic, and one had the catheter removed for persistent septicemia. Hyperalimentation was more effectively delivered with the double lumen catheter which provides a route for infusion of hyperalimentation solutions at a constant rate during infusions of blood products, antibiotics, and other fluids.
