Further discussion on measures of infection control in operating room in Germany: Questions about infection rate of laminar flow operating rooms

 Medical statistical studies on the infection rate of laminar flow operating rooms has been published by Brandt et al in Germany and a researcher in China. The author carries out a deep investigation and a serious discussion, and points out that there are three misleading points in the two articles: misleading in logic, method and direction, and three neglects: the neglect of air microorganism, laminar flow and the Architectural technical code for hospital clean operating department. Finally, points out that laminar flow is a high-end clean technology. At present, laminar flow is not a problem of choice, but a contradiction between popularization and improvement.
