Hospital experiences often are punctuated with pain related to common procedures, such as venipuncture. An alternative to venipuncture involves obtaining samples from an existing peripheral vascular saline lock device. To validate such a collection, this study compared the accuracy of serum chemistry tests performed on samples taken concurrently from the saline locks and by phlebotomy. No clinical differences were noted within the 17 sets of ion assays, and both potassium and chloride determinations demonstrated no significant statistical differences between the sample groups. Documented rates of sample hemolysis (21%) and difficulties experienced in collection suggest that blood sampling from an existing peripheral saline lock device is best suited to inpatients undergoing multiple blood sampling necessitated by short-term investigative procedures or crisis management.
医院经历常常被与诸如静脉穿刺等常见操作相关的疼痛所打断。静脉穿刺的一种替代方法是从现有的外周血管生理盐水留置装置获取样本。为验证这种采集方法，本研究比较了同时从生理盐水留置装置和通过静脉穿刺采集的样本所进行的血清化学检测的准确性。在17组离子分析中未发现临床差异，并且钾和氯的测定在样本组之间均未显示出显著的统计学差异。记录的样本溶血率（21%）以及采集过程中遇到的困难表明，从现有的外周生理盐水留置装置采血最适合因短期检查程序或危机管理而需要多次采血的住院患者。
