Abstract
For the purpose of examining the influence of a large blood transfusion after the surgery for pulmonary tuberculosis the observations on bleeding time, coagulation time, serum bilirubin and B. S. P. test were made.
There was no interrelationship between the quantity of blood transfusion and bleeding and coagulation times.
The incidence of serum hepatitis was not related to the quantity of blood transfusion nor to preoperative liver function.
Many problems of the quantity of blood loss during the operation for pulmonary tuberculosis still remain to be solved.
