摘要：

目的设计输液滴速计数器,评价其应用效果。方法输液滴速计数器由输液器卡扣、显示器、启动/模式切换按钮、电池、蜂鸣器、红外线感应区等组成。在试验室中,将该计数器测得的输液滴速与输液泵设定的输液滴速进行比较,评价该计数器滴数计数的准确率。采用便利抽样法,选取2020年3月—5月在上海市某三级甲等综合医院急诊科输液的200例患者作为应用对象,按患者输液时座位的序号分为试验组103例、对照组97例。试验组使用计数器进行计数,对照组使用人工计数的方式进行计数。比较两组预计输液完成时间与实际输液完成时间的差值,静脉炎、外渗、导管堵塞、回血的发生率,患者满意率。收集护士使用该计数器的满意率。结果在试验室检测中,该计数器滴速计数的准确率为99.6%,计数器显示滴数与输液泵设置滴数比较,差异无统计学意义 (P=0.829) 。临床应用过程中,试验组预计输液完成时间与实际输液完成时间的差值小于对照组,回血发生率低于对照组,患者满意率高于对照组,差异具有统计学意义 (P<0.05) 。护士满意率为96.1%。结论输液滴速计数器的准确性较高,使用该计数器有利于控制输液滴数,降低回血的发生率,提高患者满意率。

Abstract:

Objective An infusion drip counter is designed,and its application effect is evaluated. Methods An infusion drip counter was self-developed,and it consists of infusion set buckle,display,start/mode switch button,battery,buzzer,infrared sensor area,etc. In the laboratory,the infusion drip rate measured by the drip counter was compared with the infusion drip rate set by the infusion pump,in order to evaluate the accuracy of the counter. Convenience sampling method was used to recruit 200 emergency patients with infusion admitted from March to May 2020 in a tertiary hospital,and they were divided into an experimental group (n=103) and a control group (n=97) according to the seat number during the infusion. The experimental group used the drip counter for counting,and the control group used the manual counting for counting. The difference between the predicted infusion completion time and the actual infusion completion time was compared,as well as the incidence of the intravenous infusion complications such as phlebitis,extravasation,tube blockage,blood return,and the patient satisfaction rate in the 2 groups. The satisfaction rate of nurses using the drip counter was evaluated. Results In the laboratory test,the accuracy of the drip rate counting of this counter was 99.6%,and the drip rate displayed by the counter was compared with the drip rate set by the infusion pump,and the difference was not statistically significant (P=0.829). In the process of clinical application,the difference between the predicted infusion completion time and the actual infusion completion time of the experimental group was smaller than that of the control group;the incidence of blood return was lower than that of the control group;the patient satisfaction rate was higher than that of the control group;the differences were statistically significant (P<0.05). The satisfaction rate of nurses was 96.1%. Conclusion The infusion drip counter has high counting accuracy. The use of this drip counter is beneficial to control the infusion drip rate,reduce the incidence of blood return,and improve the patient’s satisfaction rate.
