Have a few cannulae of different types to hand, as frequent
attempts may be needed in diffi cult cases.
Have plenty of gauze ready to catch blood loss.
Palpate lightly so as to not obliterate fl ow.
If the cannula, or guidewire, will not advance, aspirate with a
5-mL syringe and withdraw slowly until pulsatile fl ow is found
before attempting to advance the cannula again.
If a FloSwitch™ cannula is sited in the vessel but fails to advance
fully, conversion to a Seldinger technique by passing the
guidewire through the device may help.
The artery may go into spasm; if so, change site or wait until the
pulse returns.
Limit your number of attempts to minimise damage to the
vessel.
Don't forget to apply pressure to puncture sites for at least
3 minutes after failed attempts and removal.
