Cultures of blood drawn through indwelling intravascular venous and arterial cannulas were compared with those of blood drawn simultaneously by percutaneous venipuncture. In 92% of 174 comparisons, the results were identical. Cultures of blood drawn through indwelling intravascular catheters are as reliable as those of percutaneously obtained samples. In addition, the speed, ease, and lack of trauma in obtaining blood for cultures in critically ill patients further recommends this technique.
将通过留置血管内静脉和动脉插管采集的血液培养物与同时经皮静脉穿刺采集的血液培养物进行比较。在174次比较中，92%的结果是相同的。通过留置血管内导管采集的血液培养物与经皮采集的样本一样可靠。此外，为重症患者采集血培养标本时的速度、便捷性和无创性进一步表明了该技术的优势。
