Central vs Peripheral Line Defined
- The distinction between central and peripheral lines is largely arbitrary but important clinically.
- Central lines end in larger central veins while peripheral lines do not, affecting infection risk.
Infectious Risk Drives Distinction
- Central lines have higher infectious risk than peripheral lines, causing more morbidity and mortality.
- This difference is fundamental to why the distinction is emphasized in clinical practice.
Central Line Boundaries Are A Continuum
- The boundary between central and peripheral lines is more of a continuum than a strict cut-off.
- Factors like catheter length and tip location influence infection risk but the transition is gradual.
