概括

使用超薄管采血装置显著增加了血液培养体积和样本阳性. 这项技术有助于更好地识别患者的血液感染.

科学领域:

临床微生物学
医疗器械
诊断技术

背景情况:

在临床环境中采集低于最佳血量会影响病原体的恢复和检测时间.
血液采集技术在优化血液培养量方面的作用需要进一步调查.

研究的目的:

为了评估BD Vacutainer UltraTouch按键采血装置的性能,该装置具有超薄壁管.
为了评估它在增加收集的血液体积方面的有效性,而不是普通管.

主要方法:

在转换为UltraTouch设备之前和之后收集的血液体积进行了回顾性研究.
使用BD BACTEC FX仪器的背景代谢活动信号进行体积测量.
对样本阳性的填充量和后勤回归的分析差异.

主要成果:

转换后的平均填充量 (7. 56毫升) 明显高于转换前的 (5. 68毫升).
血液体积增加1. 88毫升导致样本阳性从7. 0%增加到7. 7% (P=0. 002).

结论:

超薄管采血装置显著增加了血液培养体积.
这种改善支持样本阳性增加,有助于识别血液感染.

Bioreactor Controls-II

In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the fermentor via a sparger...
