Infusion of fluids and drugs at very low rates may be necessary in neonatal intensive care. Marked haemodynamic fluctuations occurring during the infusion of inotropes have been shown to be due to the sticking of the plunger in the barrel of syringes used in syringe drivers. The Australian Therapeutic Goods Administration has recommended the use of volumetric or peristaltic pumps in these circumstances. We tested a number of infusion systems and found that 1. some syringes give continuous flow at low rates, and would be suitable for the delivery of inotropes, and 2. some infusion pumps provide non-continuous flow at low rates, and would not be satisfactory for the infusion of inotropes.
在新生儿重症监护中，可能需要以极低的速率输注液体和药物。已表明在输注强心剂期间出现的明显血流动力学波动是由于注射器驱动装置中使用的注射器针筒内活塞卡住所致。澳大利亚治疗用品管理局已建议在这些情况下使用容量泵或蠕动泵。我们测试了多种输注系统，发现：1. 一些注射器在低速率下能提供连续流动，适用于输注强心剂；2. 一些输注泵在低速率下提供非连续流动，对于输注强心剂而言并不理想。
