A Study upon the Changes of Hemoglobin and Hematocrit between Preoperative and Postoperative Values / 대한마취과학회지

ABSTRACT

Because of the increasing numbers of the operations requiring transfusions day by day, there is increase in transfusion reaction, and recently the shortage of blddd supply and the requirements for component transfusion are enhanced. In order to overcome the shortage of blood supply and to prepare the standard for com-ponent transfusion, the author compared the preoperative heraoglebin and hematocrit with postperative ones, and the conclusions are as followings. 1) There were no significant changes in hemoglobin and hematocrit of both male and female groups, as from preoperative values of 17.4+/-1.87g% and 42+/-5.0% to postoperative values of 14,2+/-1.79g% and 42+/-5.0% in male group, and from preoperative values of 12.8 +/-1.15 g% and 77+/-3.2% to postoperative values of 12.6+/-1.43g%, 37+/-4.0% in female group respectively. 2) There were no significant changes of hemoglobin and hematocrit according to the distributions of age and operating trite and the amount of b1ood transfusion. 3) There was significant decrease in hemoglobin of the transfusion group, but nut of the non-transfusion group, from 13.5+/-1. 59% to l3.3+/-1,73g%(P<0.05), but the practical sig- nificance of the change below 1.5% was considered negligible. 4) In the distribution of departments, there were significant changes in hemoglobin and hematocrit of obstetric gynecologic surgery from 12,8+/-1.24g%,37+/-3.3% to 12.3+/-1.44g%, 36+/-3.9% and hemoglobin of orthopedic surgery from 13.9+/-1.65g% to 13.2+/-1.88 g% respectively, but their practical significance of the changes in the range of 2 to 5% was also considered negligible. 5) There was significant change in hemoglobin of non cancer group, but not of cancer group from 13.6+/-1,65 g% to 13.4+/-1.75 g% (P<0.05) But the practical significance of the change under 1.5% was also considered negligible. From the about results, it is suggested that there are rooms for saving blood from curt-ailing transfusion of patients who were given one pint of blood only and even with multiple pints of blood, and also there are a great possibility for component transfusion after-wards but with slight limitation.
