Intraoperative autotransfusion is an advantageous and safe method of blood replacement. In our clinic this method is established as a routine procedure in all cases with suspected massive bleeding. We used the IAT in 141 cases of surgical haemorrhage. The mean indications for IAT in surgery were emergency operations necessitated by blunt abdominal or thoracic trauma. Altogether 390 l of blood have been retransfused with an AT -- volume per patient ranging from 1 to 20 l. On an average 2,8 l per patient were transfused. Contraindications of blood replacement are tumour surgery, septic surgery, contamination by large intestinal contents and rupture of the uterus. For anticoagulation ACD-solution has been used, only in vascular surgery systemic heparinization was preferred. The main advantages of autologous intraoperative transfusion are the immediate availability of blood, the absence of the risk of hepatitis and of incompatibility reactions, reduction of pressure on the blood banks and lower transfusion costs.

A new factor VII concentrate, made from ACD plasma by a process involving successive absorptions of cryoprecipitate supernatant on DEAE Sephadex and of the resulting supernatant on A1(OH)3, was administered to 10 patients with severe factor VII deficiency. 5 patients received only one dose for treatment of a single bleeding episode, the remaining 5 were given multiple infusions (47) for spontaneous hemorrhages or for the prevention of surgical bleeding. In vivo factor VII recovery ranged from 43 to 126% (average 88%) of the assayed in vitro activity of the concentrate. A dose of 0.5 u/kg was found to produce a 1% rise of the plasma factor VII levels. The mean half-life on injected factor VII as assessed in 7 kinetic studies was 205 min (range 168--234). Spontaneous bleeding was easily controlled by the concentrate and major surgical procedures (two tonsillectomies) could be performed without complications. 1 patient developed HBSAg positive hepatitis, but otherwise no serious side effects were observed. Factor VII concentrate reduced the risk of precipitating circulatory overload associated with the use of plasma and avoids the unnecessary rise of factor II, IX and X which follows prothrombin complex concentrates.

The technique of intraoperative autotransfusion (AT) is being used to date only in a few individual clinics. Since there is a clinically safe and economical AT-apparatus available the routine application of this rational blood replacement method is easy to perform. The authors have used this technique altogether in 111 patients, applying the Bentley-ATS-machine in the last 69 cases. In a previous series of 42 cases AT was used for ruptured ectopic pregnancy, in the series of 69 surgical cases for hemothorax or intraabdominal hemorrhages of mainly traumatic origin. The most frequent indications for AT in emergency surgical operations were ruptures of spleen and liver, and in elective surgery for portocaval shunt. Altogether 247 litres of blood have been retransfused with an AT-volume per patient ranging from 0,5 to 15 litres. For anticoagulation generally ACD was used, only in vascular surgery was heparin preferred. Methodical complications have not been seen. Technique, indications, consequences and possible complications of AT are described. The main advantages of autologous intraoperative transfusion are the immediate availability of blood, the absence of the risk of hepatitis and of incompatibility reactions, reduction of pressure on the blood banks and lower transfusion costs. The authors therefore believe that the possibility of intraoperative AT should exist at every surgical and gynecological clinic.

Autotransfusion of shed mediastinal blood is expected to be adopted as a technique to reduce transfusion thus preventing various complications such as hepatitis, AIDS, and GVHD. We report the usefulness and problems of a new device-Solcotrans Plus, which only requires connection to wall suction. This device consists of three parts: suction, reservoir bag, and filter for autoinfusion. After setting the suction and reservoir bag primed with anticoagulant, ACD or heparin, and connecting the unit to a wall suction, we performed autotransfusion of shed blood through the filtration component in ICU after operation. Postoperative hematological and biochemical examinations revealed no complications or adverse effects of autotransfusion. This device is available, simple to handle, and is useful for returning shed blood. We believe that this device will be effective for non-blood open heart surgery or reduction of transfusion.
