Short peripheral catheters (SPC) are an existing conduit into many patients' veins and line draws from SPC are a desired method of routine blood collection especially in difficult venous access patients. The PIVO device facilitates blood collection through SPC and is being used clinically in a number of hospitals. This study aimed to determine the appropriate wait time following a flush and the minimum waste volume required to obtain an undiluted blood sample when using the PIVO device and how that differed from current guidelines from SPC line draws. A clinical study was conducted examining the analyte results of samples drawn with PIVO through a SPC at varying wait times following a saline flush. Both an initial waste volume and a postwaste sample were compared to a venipuncture control. The resulting samples showed no saline dilution as measured by sodium and creatinine results at all studied wait times. These findings suggest that blood collections using the PIVO device can produce a clinically valid sample with a 30-second wait following a SPC flush and no waste volume prior to sample collection.
短外周导管（SPC）是许多患者静脉的现有通路，通过SPC进行采血是常规血液采集的一种理想方法，尤其是对于静脉穿刺困难的患者。PIVO装置便于通过SPC进行采血，并且正在多家医院临床使用。本研究旨在确定使用PIVO装置时冲洗后合适的等待时间以及获取未稀释血样所需的最小废弃血量，以及这与SPC采血的现行指南有何不同。进行了一项临床研究，检查在盐水冲洗后的不同等待时间通过SPC使用PIVO采集的样本的分析物结果。将初始废弃血量和废弃后样本与静脉穿刺对照进行比较。在所有研究的等待时间，通过钠和肌酐结果测量，所得样本均未显示盐水稀释。这些发现表明，使用PIVO装置采血时，在SPC冲洗后等待30秒且采集样本前无废弃血量，可获得临床有效的样本。
