Simultaneous Bilateral Central Catheters: A Safe Technique

Abstract

Optimal central catheter care includes restriction on usage for blood sampling and blood product administration to enhance continued sterility, but our experience with 25 children receiving bone marrow transplants after cytoreduction challenges this concept. Prior to transplantation, bilateral percutaneous subclavian vein silastic catheters were inserted without incident, one utilized for continuous nutritional support in caloric quantity to assure body weight maintenance, and the contralateral catheter utilized for daily venous sampling plus administration of medications including blood products. Patients subsequently entered a protective environment and biweekly surveillance cultures were monitored. Nutritional therapy was given for 876 days through 53 catheters. One patient developed culture-proven sepsis, an organism first cultured from the skin. The patient complication rate of 4% and the per diem rate of 0.11% in this immunocompromised population compares favorably to the 10.5 and 0.32% incidence we previously reported for 200 children with unilateral catheters. These data demonstrate that bilateral central catheters can be safely utilized in children for nutrition and sampling.
