OBJECTIVES
to analyze the mean direct cost and peripheral venous access length outcomes using devices over needle with and without extension.
METHODS
quantitative, exploratory-descriptive research. Venous punctures and length of the devices were followed. The mean direct cost was calculated by multiplying the time (timed) spent by nursing professionals by the unit cost of labor, adding to the cost of materials.
RESULTS
the total mean direct cost of using devices "with extension" (US$ 9.37) was 2.9 times the cost of using devices "without extension" (US$ 4.50), US$ 7.71 and US$ 2.66, respectively. Totaling 96 hours of stay, the "device over needle with extension" showed a lower occurrence of accidental loss.
CONCLUSIONS
the use of the "device over needle with extension", despite its higher mean direct cost, was more effective in favoring adequate length of peripheral venous access.
目的
分析使用带延长器和不带延长器的设备的平均直接成本和外周静脉通路长度结果。
方法
定量、探索性描述性研究。对静脉穿刺和设备长度进行了随访。平均直接成本是通过将护理专业人员花费的时间（计时）乘以劳动力的单位成本，再加上材料成本来计算的。
结果
使用带延长器的设备的总平均直接成本（9.37 美元）是使用不带延长器的设备的成本的 2.9 倍（4.50 美元），分别为 7.71 美元和 2.66 美元。总共 96 小时的住院时间，“带延长器的针上装置”显示出意外损失的发生率较低。
结论
尽管使用带延长器的“针上装置”的平均直接成本较高，但它在外周静脉通路长度方面更有效。
