In a study to determine the presence of bacteria on ultrasonic transducers, the authors found micro-organisms in 82% of cultures. The results show that 70% isopropyl alcohol is not a consistently effective germicide for the sterilization of transducers. The presence of bacteria, however, appears to be of little clinical consequence.
在一项确定超声换能器上细菌存在情况的研究中，作者发现82%的培养物中存在微生物。结果表明，70%的异丙醇并非对换能器进行消毒的始终有效的杀菌剂。然而，细菌的存在似乎对临床影响不大。
