TPN Catheter Sepsis: Lack of Effect of Subcutaneous Tunnelling of PVC Catheters on Sepsis Rate

Abstract

In an effort to diminish the incidence of catheter related sepsis in total parenteral nutrition, the effect of a 10-cm long subcutaneous tunnel was studied in a prospective randomized manner. This tunnel created a longer anatomical distance between puncture site of the catheter and the subclavian vein. In the control group, a direct puncture technique was employed. Eighty-one catheters (group A) were inserted according to the direct technique, 69 (group B) were tunnelled. Catheter sepsis was defined as an episode of clinical sepsis for which no other cause can be identified and which resolves upon removal of the catheter. No significant differences were noted between the two groups, suggesting that tunnelling of subclavian PVC catheters does not diminish the incidence of catheter related sepsis.
