A Clinical Study on Hemolysis during Transfusian of Bank Blood / 대한마취과학회지

ABSTRACT

During massive transfusions especially under pressure, considerable hemolysis has been expected. It had been assumed that hernolysis would increase with increasing age of the bank blood, increasing pressure and with decreasing bore of the needle. Moss and Stauntan, however, found that hemolysis actually increased when blood was forced through larger bore needles. The authors have studied the magnitude of hemolysis according to various needle sizes under ordinary clinical transfusion conditions, and concluded as follows 1) Hemolysis was maximum when a 18G needle was used and minimum with use of a 22G. needle regardless of the age and temperature of the bank blood, 2) Hemolysis increased with increasing age of the bank blood. 3) When the needle size was constant, hemolysis was not affected by warming of the bank blood.
