title: [Analysis of results of 1847 cultures of bacteria pre- and post-cardiopulmonary bypass].
abstract: From Apr. 1984 to Jan. 1990, 1847 samples were taken in the operating room pre-and post-CPB-operatively and were cultured for observation of bacteria. The results showed that the sterilizing method for the articles used in the operating room was reliable. The positive culture rate of blood remnant from CPB machine was 18.4%. The authors believe that the increase of blood contamination rate during the operation may be related with the following factors: (1) The inevitably increased number of bacteria in the air of the operating room during CPB operation, (2) prolonged CPB time (greater than 80 min); (3) wet and warm weather.
