We compared fluid delivery, both in vitro and in vivo, using various combinations of fluid sets and intravenous catheters. Administration sets were a minidrip, a maxidrip, and a blood infusion set. The catheters included 14-, 16-, 18-, and 20-gauge short catheters, 16- and 19-gauge long catheters, and an 8 French catheter introducer for flow-directed pulmonary arterial lines. Blood infusion tubing alone delivered fluid at 3.12 +/- .07 mL/second, significantly faster than either the maxidrip (2.59 +/- .06, P less than .01) or the minidrip (0.56 +/- .02, P less than .001). The 8 French introducer provided no additional resistance to the flow of the maxidrip or blood infusion set when used in combination with an anesthesia extension. All the other catheters slowed flow significantly. Percutaneous insertion of an 8 French catheter introducer connected to blood administration tubing allows for rapid delivery of fluids and for subsequent insertion of a Swan-Ganz catheter, which is often necessary in critically ill patients.
我们在体外和体内比较了使用不同输液器和静脉导管组合时的输液情况。输液器包括微量输液器、常规输液器和输血器。导管包括14、16、18和20号短导管、16和19号长导管以及用于血流导向肺动脉导管的8法式导管导入器。仅输血器的输液速度为3.12±0.07毫升/秒，明显快于常规输液器（2.59±0.06，P<0.01）或微量输液器（0.56±0.02，P<0.001）。当与麻醉延长管一起使用时，8法式导管导入器不会给常规输液器或输血器的血流增加额外阻力。所有其他导管均显著减慢了流速。经皮插入连接到输血管道的8法式导管导入器可实现快速输液，并便于随后插入Swan-Ganz导管，这在重症患者中通常是必要的。
