Once fl ashback is achieved, stop advancing the needle and with-
draw the plunger to collect the required blood.
Following collection, withdraw the needle, apply pressure over
6
the access site using cotton wool and distribute the blood into
the required bottles.
Handy hints/troubleshooting
If using the needle and syringe technique, loosen the plunger
several times before taking the blood - this should avoid the
plunger sticking.
Encourage venodilation by asking the patient to repetitively clench
and release his or her fi st, and by gently tapping on the vein.
Tether the skin with your spare hand to help fi x the vein.
Consider whether a cannula is also needed - if so, blood can
be taken from the cannula after insertion, by using either a
Vacutainer™ technique or a needle and syringe (see Chapter 10).
Take great care when labelling cross-match and group and save
samples - the smallest of errors can make the sample void. Always
handwrite these samples and include all the patient's details.
Remember femoral triangle anatomy with the acronym NAVY -
from lateral to medial there is n erve, a rtery, v ein and then Y -fronts!
Include as much clinical information on the forms as possible,
especially microbiology forms.
