Figure 4

Kaplan-Meier curves for catheterisation success time as a function of a puncture site. Ultrasound-guided catheterisation of the cephalic vein in the proximal forearm had the shortest catheterisation time (cephalic, P <0.001 versus saphenous and dorsal; saphenous, P = 0.31 versus dorsal, log-rank test). The median catheterisation times for the three groups were as follows: the cephalic group, 30 seconds; the saphenous group, 40 seconds; and the dorsal group, 47 seconds.
