Assembly of extracorporeal circuit with Efferon® device and hemofilter in “PREfilter” mode on RRT machine
What do you need?
0,9% saline solution bag, 1 liter
Plastic bag for priming solution, 2 liter
DIN-Luer bloodline,
2 pcs
Heparin,
10.000 ME
DIN-DIN
bloodline
Clamps,
4 pcs
1
Assemble the extracorporeal
circuit of the RRT machine
according to its user manual.
2
Add 10.000 ME heparin
to saline solution and mix
it to prepare the rinsing
solution.
3
Connect DIN-Luer bloodline 1
with priming solution bag.
Fill the bloodline with the priming
solution using gravity. Attach
the clamp to the bllodline
4
Mount the Efferon® device
in vertical position.**
5
Remove the cap from bottom port of
the Efferon® device and connect the
pre-filled DIN-Luer bloodline 1 to it.
6
Remove the cap from upper
port of the Efferon® device and
connect the empty DIN-Luer
bloodline 2 to it.
7
Connect the plastic bag for
rinsing solution to DIN-Luer
bloodline 2.
8
Remove the clamp from
DIN-Luer bloodline 1 and
rinse the Efferon® device
using gravity.
9
Put the clamp on DIN-Luer bloodline 1 and 2 after the priming is finished.
10
Disconnect DIN-Luer
bloodline 2 from the
upper port of the Efferon®
device and attach
DIN-DIN bloodline to it
11
Remove the clamp from the DIN-Luer bloodline 1. Fill the DIN-DIN bloodline with priming solution, then attach the clamps to both blood- lines.
12
Stop the blood pump
of RRT machine
13
Put the clamps on inlet
and outlet bloodlines
of the hemofilter
14
Disconnect the DIN-Luer
bloodline 1 from bottom port
of the Efferon® device. Take
care of air bubbles not
to enter inside.
15
Disconnect the “red”
bloodline at the inlet
of the hemofilter
16
And connect it to lower
port of the Efferon® device
17
Connect the DIN-DIN
bloodline and inlet port
of hemofilter.
18
The circuit is ready.
Remove all the clamps
and start the blood pump.
* If RRT procedure is already being performed and Efferon® device should be installed in previously assembled circuit, stop the procedure, reinfuse the blood and go to recirculation mode.
** Efferon® device is symmetric, flow rate should be oriented from bottom to top.
Anticoagulation level before the start and during
the extracorporeal treatment:
— 160-210 seconds of ACT
— 60-80 seconds of aPTT
the extracorporeal treatment:
— 160-210 seconds of ACT
— 60-80 seconds of aPTT
Recommended duration of use is 6-12 hours (up to 24 hours)
