Rinse Procedure
CAUTION:
To minimize air generation which could create air locks within
the fibers, use a saline rinse on the blood side of the dialyzer
before attaching the dialysate connectors to the dialyzer.
- Place the dialyzer into the holder on the
dialysis machine. Do not remove the port caps.
- Prime the arterial blood line with saline,
purging all air from the line.
- Remove the arterial blood port cap from the
dialyzer and attach the arterial blood line.
- Turn the dialyzer, in its holder, until the
venous end is up. Remove the venous blood port cap from the dialyzer,
then attach the venous blood line to the dialyzer. Prime the dialyzer
until a minimum of 500 cc has drained from the saline bag. Collect
and dispose of the solution exiting from the venous blood line.
CAUTION:
Before continuing, ensure that all air has been purged from
the blood circuit using standard priming procedures. Use more
saline if necessary.
- Prepare for recirculation and dialysis to
remove the remaining Peracidin from the extracorporeal circuit.
Connect the arterial and venous blood lines at the fistula connectors.
- Attach the dialysate connectors to the dialyzer.
Begin dialyzing and set the blood pump speed to 300 ml/minute.
Leave the saline line open to replace any solution removed during
this step. An ultra filtration controller should be set at a removal
speed of one (1) liter per hour. A negative pressure of 100 mmHg
may be used for other dialysis systems. Check the extracorporeal
circuit for the presence of air. Once all air is removed, turn
the arterial end up into its proper position for more effective
dialysis. Complete removal of all solution should be accomplished
in less than 10 minutes for cellulose-based membranes; some synthetic
membranes, such as polysulfones, may take longer.
