Abstract
The occurrence of C-reactive protein (CRP) was studied after 167 otolaryngological operations. CRP appeared in blood serum of patients in 113 cases out of 167. In the case of tonsillectomies the incidence of positive tests for CRP was the highest, 47 out of 51. Tonsillectomies and/or adenoidectomies done under general anesthesia showed a lower frequency of positive CRP tests than tonsillectomies under local anesthesia. In the series studied, there were no postoperative complications, and therefore other points have to be taken into consideration when assessing the reasons why CRP did not appear in connection with all operations of the same kind.
