degradation over time, due to suction)Ĭomposition of blood from intercostal catheter incomplete washing/ inadequate filtration leading to contamination with activated leucocytes, cytokines, and other microaggregates.contamination with drugs and cleansing solutions.thrombocytopenia and coagulopathy (only if large volumes).haemodilution (do not expect significant rise in Hb).The salvaged RBCs may be transfused immediately or within 6 h.The salvaged RBCs are then re-suspended in normal saline with a resultant haematocrit of 50–80%.The RBCs are then washed and filtered across a semi-permeable membrane, which removes free haemoglobin, plasma, platelets, white blood cells, and heparin.Separation of the components is achieved by centrifugation.The anticoagulated blood is then passed through a filter and collected in a reservoir.Double lumen suction device removes blood from operative field and mixes with heparinized saline.Follow instructions for each specific type of collection system.Most systems can be used to re-infuse shed blood up to 6 hours after collection without heparin or other products.No need to anticoagulate the blood (see blood composition in ‘other information’).Use an inline leucocyte depletion filter.Connect the autotransfusion cannister to the chest tube collection system before the chest tube goes in (otherwise most of the blood will be lost).cell saver - separates components by centrifugation.the other lumen adds a predetermined volume of heparinized saline to the salvaged blood one lumen suctions blood from the operative field Filled canisters can then be hung like a bag of blood from the blood bank.The canisters are used to collect shed blood.Most chest drain collection systems have optional autotransfusion canisters that connect to the chest tube inline with the collection system.penetrating chest trauma, where a stab or gunshot could injure stomach or colon and violate the diaphragm Don’t use the blood if it is likely to be contaminated.primarily used for cardiac surgery, orthopedics, neurosurgery, vascular surgery and urology consider intraoperatively where significant blood loss (>1000 ml) is expected, where patients refuse allogeneic blood products or they are anaemic haemothorax due to trauma - consider for any ICC insertion in trauma.collection system used to recycle blood from a bleeding patient.
