Vascular access in cystic fibrosis--does size matter?
Vascular access is an important part of patient management in cystic fibrosis. In most instances, vascular access is straightforward. However, a single bad experience with venepuncture has a lasting impact. Clinical experience suggested that for some individuals a smaller, shorter intravenous catheter (Leaderflex 22G, 0.7 mm 8.0 cm, Vygon) might be a suitable alternative to standard vascular access via a standard long-line (2 Fr or 3 Fr Nutriline, Vygon).


METHODS
Between September 2002 and May 2004 we offered a free, fully informed choice between a standard 30 cm long line or a shorter (8 cm) Leaderflex line and audited this change in practice.


RESULTS
A total of 56 lines were inserted over the study period. Data were available for 54 of these (22 Leaderflex and 32 standard long lines). Mean and median line survival was omparable. Leaderflex lines survived for a mean of 12.2 days and median of 14 days. Standard long lines survived for a mean of 12.6 days and median of 14 days.


CONCLUSIONS
Leaderflex lines offer a well-tolerated alternative to standard long lines for the administration of a 14-day course of intravenous antibiotics. Their reduced size and cost offer advantages to patients and doctors.
