Blood culture records from 1994 to 1995 from five U.S. medical centers all using the Difco ESP continuous monitoring blood culture system were reviewed retrospectively. Among a total of 7,362 isolates of bacteria and yeasts, only 0.1% of possibly significant isolates would have been missed had blood cultures been routinely incubated for 4 days instead of the 5 days recommended by the manufacturer. Conversely, numerous contaminants, detected only on day 5, would have been eliminated by a 4-day incubation period.
回顾性分析了1994年至1995年期间来自美国五个医疗中心的血培养记录,这些中心均使用Difco ESP连续监测血培养系统。在总共7362株细菌和酵母菌分离株中,如果血培养按常规培养4天而非制造商推荐的5天,仅0.1%可能具有重要意义的分离株会被漏检。相反,许多仅在第5天检测到的污染物,通过4天培养期就会被排除。
