We clinically studied the incidence of postoperative infections and the factors responsible for such infections, including blood loss, duration of operation, cleanliness of operation, and systemic disease. The subjects comprised 422 inpatients who underwent operations under general anesthesia at the 1st Department of Oral Surgery, Hokkaido University during the 5 years from 1988 to 1992. The results were as follows: 1) The incidence of the postoperative infection was 12.1%. 2) With regard to the cleanliness of operation, the incidences of semi-aseptic operations, contaminated operations, and aseptic operations were 15.7%, 5.6%, and 0 %, respectively. 3) Operations with a long duration and a high volume of bleeding tended to have a higher incidence of postoperative infection. 4) Operations for malignant tumors tended to have a higher incidence of postoperative infection. 5) Patients with systemic disease tended to have a higher incidence of postoperative infections. 6) The infected cases had longer durations of antibiotic use and hospitalization.
