The use of intravenous administration systems incorporating 3-mm internal diameter tubing is becoming more common in hospital practice. The maximum flow-rate of crystalloid solutions through 3-mm-diameter tubing is compared to that through conventional 4-mm tubing when connected to standard large-gauge intravenous cannulae. Lengths of intravenous tubing between 80 cm and 200 cm were tested in combination with 16 gauge, 14 gauge and 13 gauge intravenous cannulae. The results demonstrated that the use of 3-mm-diameter infusion sets, or the inclusion of even short lengths of 3-mm tubing in an infusion system, limits the maximum flow that can be delivered through a cannula of size 16 gauge or larger. The reduced performance of the 3-mm tubing makes administration systems incorporating even short lengths of this diameter of tubing unsuitable in emergency situations and locations where rapid infusion of fluids is vital.
在医院实践中，使用内径为3毫米的静脉给药系统正变得越来越普遍。当连接到标准大口径静脉套管时，将晶体溶液通过3毫米直径管道的最大流速与通过传统4毫米管道的流速进行比较。对80厘米至200厘米长的静脉输液管与16号、14号和13号静脉套管进行了组合测试。结果表明，使用3毫米直径的输液器，或者在输液系统中即使包含短长度的3毫米管道，也会限制通过16号或更大尺寸套管所能输送的最大流量。3毫米管道性能的降低使得包含这种直径短长度管道的给药系统在紧急情况和快速输液至关重要的场所不适用。
