About hemolytic shock caused by transfusion of Rh-incompatible blood

The Tatar Republican Blood Transfusion Station, having been studying the issue of the Rh factor since 1956, was the center where the serologically presumptive diagnosis of hemolytic shock was confirmed during transfusion of Rh-incompatible blood. In just 5 years, 4 cases of such a shock have been identified and accurately established. In all cases, neither the Rh-affiliation of the patient's blood, nor the Rh-compatibility of the recipient's and donor's blood was made. 2 cases were mild, one was moderate and 1 was severe. In view of the practical importance of shock during transfusion of Rh-incompatible blood, we briefly describe these cases.
