[The influence of intraoperative autotransfusion (IAT) on plasmaproteins in patients with posttraumatic intraabdominal bleeding or hemorrhage during vascular surgery (author's transl)].

In 29 patients (12 vascular and 17 trauma cases) the effect of intraabdominal bleeding and surgical management under intraoperative autotransfusion on several plasmaproteins was examined. The following parameters were monitored immediately before and after autotransfusion as well as 24, 48, 72 hours and one week later, in the thawed serum: 1. albumen and the carrier proteins prealbumen, transferrin, retinol-binding protein, 2. acute phase reactants: c-reactive protein coeruloplasmin, haptoglobin, 3. fractions of complement: C1q, C3c, C5 and C 3-activator, 4. serum-cholinesterase. With usual treatment by infusion of electrolyte solutions during operation and the following days, and further applicated blood transfusion, plasma and fresh frozen plasma by clinical needs, while the immediate blood loss during operation was replaced by autotransfusion, there was no change in preoperative dates. Only at the 3rd day the typical picture of catabolic situation of the postoperative period was observed in vascular cases and not at all in trauma cases. Thus the changes were closely related to the preexisting disease or state of shock, without further detoriation by intraoperative autotransfusion. 7 days later a sometimes overshooting normalization of the parameters was observed. Only cholinesterase remained extremely low, especially in vascular cases.
