ABSTRACT
Routine frequent central venous catheter (CVC) changes in burned patients (either change in insertion site or change over guidewires) has been advocated to decrease catheter-related sepsis. The need for this management has not been verified for children with burns. We reviewed our pediatric burn population with regard to CVC sepsis rate and individual CVC longevity to confirm this traditional policy. From 1978 to 1988, 70 children admitted to the Children's Hospital of Oklahoma Burn Unit required central venous access. Patients in whom CVCs were changed frequently (FC), (n = 10; no. of CVC, 46) were compared with those in whom CVCs were changed only for mechanical complications or sepsis (NFC), (n = 60; no. of CVC, 74). There were 10 septic CVCs in each group. The difference in mean length of individual CVC use between FC and NFC was significant (4.6 v 17.7 days; P less than .01). The difference in the number of septic CVCs per total number of catheter days in each group was highly significant (FC: 10 CVC/212 d. = 0.05; NFC: 10 CVC/1,112 d = 0.009; P less than .001). This study demonstrates a significant decrease in catheter-related sepsis when CVCs are not changed on a routine frequent basis.
