We tested whether propofol or Intralipid inoculated with Staphylococcus epidermidis would promote bacterial growth within an intravenous (IV) injection hub, a site prone to bacterial contamination. In tubes incubated under optimal conditions, S epidermidis exhibited growth in Intralipid, but not in propofol. In contrast, within the IV hub incubated with either propofol or intralipid at room temperature, S epidermidis bacterial numbers declined with time, and virtually no contamination remained after 12 hours. These data suggest that certain IV lines are inhospitable for S epidermidis.
我们测试了表皮葡萄球菌接种的异丙酚或脂肪乳是否会在静脉内（IV）注射座内促进细菌生长，该部位易受细菌污染。在最佳条件下孵育的试管中，表皮葡萄球菌在脂肪乳中生长，但不在异丙酚中生长。相比之下，在室温下用异丙酚或脂肪乳孵育的 IV 管中，表皮葡萄球菌的细菌数量随时间减少，并且 12 小时后几乎没有残留污染。这些数据表明，某些 IV 线对表皮葡萄球菌不友好。
