Techniques, Materials, and Devices The Uterine Sound as a Convenient, Cost-Effective Method for Creating the Subcutaneous Tunnel for Long-Term Venous Catheters

ABSTRACT. Long-term central venous access catheters generally require creating a subcutaneous tunnel to minimize infectious complications and secure the catheter to the chest wall. Many techniques for this procedure have been reported. We describe the use of a uterine sound to create the subcutaneous tunnel. (Journal of Parenteral and Enteral Nutrition 18:81-82, 1994) Indwelling tunneled catheters are commonly placed to provide long-term central venous access for the administration of parenteral nutrition, chemotherapeutic agents, or antibiotics. Creating a subcutaneous tunnel is a necessary step in placing these catheters. Many techniques for creating this type of tunnel have been described.’- ’ Instruments used include: Alligator clamps, Kelly forceps, intestinal probes, trocar needles
