2.6.8 Interaction with other systems
The use of tube roller pumps may lead to minimal electrostatic
discharge into the tubing system due to friction on the pump segment.
As the charge is very low, these discharges do not represent a direct
hazard to patients or operators. If ECG units are used at the same time,
these discharges may, in rare cases, cause periodic interferences of the
ECG signal.
In order to minimise this interference, it is advisable to observe the
recommendations of the ECG device manufacturer, e.g.:
– Correct position of the electrodes
– Use of specific electrodes with low contact impedance
2.6.9 Restrictions
Regional anticoagulation
with citrate
Citrate anticoagulation is available for adult patients for CVVHD and
CVVHDF.
2.6.10 Risks of regional anticoagulation
If citrate anticoagulation is used in CRRT treatments, attention must be
paid to risks regarding the acid-base status and the electrolyte
concentrations. Further information (see chapter 7.3.2 on page 7-17).
Interrupting the treatment Any interruption of the treatment (by temporarily disconnecting the
patient from the extracorporeal circuit) may give rise to additional risks.
This applies particularly if the blood is not retransfused to the patient
before the treatment is interrupted.
Retransfusion of the recirculated blood causes the risk of a high volume
of citrate being infused to the patient within a short time period. This
might, in particular, result in systemic hypocalcaemia. This risk is
especially high if you failed to deactivate balancing during the entire
recirculation phase.
2.6.11 Target group
The device may only be installed, operated, and used by individuals
with the appropriate training, knowledge, and experience and for whom
proof of instruction can be shown.
