Abstract
Objective
To establish the incidence of central venous catheter erosion in a patient cohort receiving total parenteral nutrition and to examine risk factors and complications of vascular erosion.
Design and setting
Review of prospectively collected intravenous nutrition service audit records in a tertiary university hospital.
Results
Records of 1,499 patients (2,992 catheters) were studied over the 14 year period 1991–2005. Fisher's exact test was used to determine statistical significance. Five erosions occurred, representing an incidence of 0.17% per catheter or 0.28 per 1,000 catheter days. One of the five patients died from ensuing complications. Mean time to onset of symptoms was 3.6 days following catheter insertion. Symptoms/signs included dyspnoea (n = 5), chest pain (n = 2) and pleural effusion (n = 5). Diagnosis was delayed by a mean of 1.6 days. Three erosions occurred in left subclavian catheters (n = 583); two in left internal jugular catheters (n = 453). None occurred in right-sided catheters (n = 1956). The relative risk of erosion occurring in left-sided catheters compared to right was 2.9 (95% CI 2.76–3.00; p = 0.009). There was no statistically significantly greater risk of vascular erosion in subclavian than internal jugular catheters (relative risk 0.9; p = 1.0). Older age was a statistically significant risk factor (p = 0.009); female sex was not (p = 0.18).
Conclusion
In patients receiving total parenteral nutrition via central venous catheters, erosion has an incidence per catheter of 0.17% and is more likely to occur in left-sided catheters and elderly patients.
