Anticoagulant Solution
The anticoagulant solution is prepared by the operator prior to the start of the case. The solution
consists of heparin or citrate and sterile normal saline (injectable or special product for cell washing).
The ratio of heparin to saline will depend upon hospital protocol. For most cases, a suggested ratio is
30,000 I.U. of heparin in one liter of saline.
Citrate anticoagulation may be achieved by using premixed Anticoagulant Citrate Dextrose Formula A
(ACD-A) or by preparing a 3 to 4% Trisodium Citrate solutions.
Prior to collecting any blood, approximately 200 ml of the anticoagulant solution should be allowed to
accumulate in the reservoir. Once collection begins, the operator should continually be aware of the
rate at which blood is being collected and adjust the flow rate of the anticoagulant solution
accordingly:
• If heparin anticoagulant has been prepared as suggested (30,000 I.U. of heparin per liter saline),
the flow rate should be adjusted to mix one part anticoagulant with seven parts of collected fluid
(1:7 ratio). LivaNova recommends starting with a minimum rate of 100 drops per minute and
adjusting accordingly.
• If citrate anticoagulant is used, the flow rate should be adjusted to assure a 1:5 – 1:10 ratio of
anticoagulant to blood
1
. LivaNova recommends starting with a minimum rate of 1 drop per second
and adjusting accordingly
• In case of heavy bleeding, appropriately increase the rate.
During blood recovery, particularly when operating in the Automatic mode, the operator should closely
monitor the proper anticoagulant ratio. The flow of anticoagulant into the reservoir is manually
controlled by the roller clamp on the anticoagulant line. This flow must be adjusted to the rate of
blood collection from the surgical field. If the rate of collection varies without adjusting the flow of
anticoagulant, the ratio of anticoagulant to blood can be too low or too high. The blood in the
reservoir may clot if there is too little anticoagulant.
