Infusions during Treatment
It is possible to give the patient infusions/transfusions/medications
during treatment via the extracorporeal blood circuit. As a matter of
principle, transfusions and m edications are to be administered in the
venous blood line after the dialyzer.
Infusions may be administered both in the arterial blood line or in the
venous blood line, depending on type of infusion. Note especially
that any infusion/transfusion/medication given to the patient via the
extracorporeal blood circuit during treatment, must pass t he venous
drip chamber and the activated air detector.
Post-blood pump infusions
Lines for infusions are first and foremost to be connected to
the extracorporeal blood circuit post-blood pump, i.e. after
the blood pump, preferably to the venous drip chamber. The
corresponding figure shows post-blood pump connection of
infusion. The infusion line is marked
.
Since there is a positive pressure in the blood lines post-blood
pump (including the venous drip chamber), an overpressure must
be established in the infusion line. Normally, this is done by
using an infusion pump, an overpressure cuff or, if necessary, by
manually creating an overpressure.
Pre-blood pump infusions
There is also the possibility of connecting the infusion line to
the extracorporeal blood circuit pre-blood pump, i.e. before t he
blood pump. The corresponding figure shows pre-blood pump
connection of infusion. The infusion line is marked
.
Since there is a negative pressure in the blood lines pre-blood
pump, pay attention of the possibility of air entering the blood
lines. Always carefully supervise pre-blood pump infusions.
Do not use infusion pump or any other methods to create
overpressure in the infusion line.
WARNING
When using a central venous catheter, and connecting the infusion
line pre-blood pump, ensure that the arterial blood line towards
the patient is properly clamped, before the infusion is started and
during the ongoing infusion. This is to prevent air from entering
the patient's blood stream since the pressure in the central venous
catheter is sometimes negative.
