    Author: von Segesser LK, Weiss BM, Garcia E, Turina MI.
    Journal: J Extra Corpor Technol; 1993; 25(2):47-52. PubMed ID: 10148848.
    Abstract:
    Two consecutive series of patients undergoing repair of descending thoracic and thoracoabdominal aortic aneurysms with partial cardiopulmonary bypass and low systemic heparinization (activated coagulation time: ACT greater than 180 sec) for proximal unloading and distal protection were analyzed. During the surgical procedures, thoracic shed blood was recovered either with a red cell spinning autotransfusion device (n=10) or two pump suckers and Duraflo II heparin surface coated cardiotomy reservoirs (n=10). There were 5/10 acute lesions and 1/10 ruptures for the autotransfusion group versus 5/10 acute lesions and 2/10 ruptures for the cardiotomy group (NS). Extension of aortic resection (range 1-8) was 3.6+/-1.2 for autotransfusion versus 3.5+/-1.4 for cardiotomy suction (NS). Mean number of reimplanted patches for intercostal and visceral reperfusion was 0.3+/-0.6 for autotransfusion versus 0.6+/-1.0 for cardiotomy (NS). Perfusion time was 41+/-17 min for autotransfusion versus 60+/-19 min for cardiotomy (p less than 0.05) and cross clamp time was 33+/-14 min for autotransfusion versus 43+/-17 min for cardiotomy (p less than 0.01). Total heparin dose was for 9500+/-2100 IU for autotransfusion versus 9800+/-1300 IU for cardiotomy (NS). The mean of the lowest ACTs measured during perfusion was 281+/-121 sec for autotransfusion versus 258+/-58 sec for cardiotomy (NS). The total protamine dose given was 7800+/-2100 IU for autotransfusion versus 9700+/-1900 IU for cardiotomy (p less than 0.05). The volume of washed red cells prepared was 3186+/-1318 ml for autotransfusion versus 0 for cardiotomy (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
