Several studies have evaluated the effect of large-bore tubing and various intravenous (IV) catheters on rapid fluid resuscitation. This study combines available equipment, which has been demonstrated to increase IV flow rate, into a system. This system is then compared with one commonly used for IV fluid infusion in hypovolemic patients. The new system requires significantly less (P less than 0.0005) time for both drainage of fluid and changing of IV containers. The improvement in flow rate can be attributed to the use of a rapid inflation/deflation pneumatic pressure device instead of the conventional hand-pumped pressure bag and the decrease in resistance through both the large-bore IV tubing and 12-gauge catheter. The rapid manipulation of IV bags is made possible by the rigid structure and the rapid inflation/deflation ability of the external pump. The possibility of faster change of IV bags and an increase in flow rate make this system a practical tool in the treatment of severely hypovolemic patients.
多项研究评估了大口径输液管及各种静脉（IV）导管对快速液体复苏的影响。本研究将已证明能提高静脉输液流速的现有设备组合成一个系统。然后将该系统与低血容量患者常用的静脉输液系统进行比较。新系统在排液和更换静脉输液容器方面所需时间均显著减少（P小于0.0005）。流速的提高可归因于使用了快速充气/放气的气动压力装置，而非传统的手动加压袋，以及大口径静脉输液管和12号导管的阻力降低。外部泵的刚性结构和快速充气/放气能力使得能够快速操作静脉输液袋。静脉输液袋更快更换的可能性以及流速的提高使该系统成为治疗严重低血容量患者的实用工具。
