Fluid-delivery rates of five small-volume infusion-pump syringes were compared. The study consisted of a comparison of the infusion-pump syringes in their respective infusion pumps (1) set for continuous delivery at 1 mL/hr, (2) set for continuous delivery at 3 mL/hr, and (3) set to deliver 1-mL bolus volumes during continuous delivery at 4 mL/hr. The Life-care prefilled 30-mL syringe (Abbott), the DBL 30-mL syringe no. 770205 (DBL Inc.), and the Pump-Jet 30-mL syringe no. 1931 (International Medication Systems) were tested in the Lifecare PCA Plus II infusion pump no. 4100 (Abbott). The 30-mL Pump-Jet syringe no. 1911 (International Medication Systems) and the DBL 30-mL syringe no. 709700 (DBL Inc.) were tested in the Stratofuse PCA infusion pump (Baxter). The infusion pumps were set to deliver fluid continuously at 1 mL/hr for 30 hours, and the solutions were collected separately and weighed. The procedure was repeated with the infusion rate set at 3 mL/hr for 10 hours. For the third part of the study, each syringe was tested to deliver 1-mL boluses with 0, 5, 15, and 25 mL removed from the syringe. The solutions were collected and weighed before and after each bolus was delivered. The volume of solution collected was calculated by using the specific gravity of the solution. The syringes delivered significantly different volumes during the first hour of infusion at both the 1- and 3-mL/hr rates. Differences also existed across time for most of the syringes. Bolus volumes varied greatly after infusion of 0 or 5 mL of fluid but were acceptable for the remainder of the infusions.(ABSTRACT TRUNCATED AT 250 WORDS)
比较了五种小容量输液泵注射器的液体输送速率。该研究包括在各自输液泵中对输液泵注射器进行比较：(1) 设置为以1 mL/小时持续输送；(2) 设置为以3 mL/小时持续输送；(3) 设置为在以4 mL/小时持续输送期间输送1 mL推注量。在型号为4100的Life-care PCA Plus II输液泵（雅培公司）中测试了Life-care预填充30 mL注射器（雅培公司）、DBL 30 mL 770205号注射器（DBL公司）和Pump-Jet 30 mL 1931号注射器（国际药物系统公司）。在Stratofuse PCA输液泵（百特公司）中测试了30 mL Pump-Jet 1911号注射器（国际药物系统公司）和DBL 30 mL 709700号注射器（DBL公司）。输液泵设置为以1 mL/小时持续输送30小时，溶液分别收集并称重。将输液速率设置为3 mL/小时重复该过程10小时。对于研究的第三部分，每个注射器在从注射器中抽出0、5、15和25 mL后测试输送1 mL推注量。在每次推注前后收集并称重溶液。通过使用溶液的比重计算收集的溶液体积。在1 mL/小时和3 mL/小时的速率下，注射器在输液的第一小时输送的体积有显著差异。大多数注射器在不同时间也存在差异。在输注0或5 mL液体后推注量差异很大，但在其余输注过程中是可接受的。（摘要截短于250字）
