Abstract
The authors have observed the curative effect and bleeding of the patients of idiopathic bleeding, especially nasal bleeding, in the region of otorhinolaryngology, using Thrombotest Owren, composite reagent to estimate the activity of four factors of blood-coagulation. Picking up at random 37 patients hospitalized at this clinic for operation and having normal bleeding time, the authors applied this test for screening. Examinations after medication of various hemostatics and postoperative examinations were also carried out. The average ante-operative thrombotest activity of all cases was 60 %, which was a little lower than that of normal people, while that of the patients of chronic tonsillitis was remarkably low (42. 4 %). The decrease of the postoperative thrombotest activity was conspicuous in the following order: extraction of malignant tumors, tonsillectomy, Sinusotomy. The authors thought that much care should be taken in tonsillectomy as general influence was so great. They thought that K1 was the most effective hemostatic.
