微量注射泵延长管长度调节器在ICU患者临床应用的效果初探

Preliminary study on clinical effect of microinjection pump extension tube length regulator in patients with ICU

目的制作一种实用型微量注射泵用延长管长度调节器(以下简称调节器),并观察其在临床中应用的效果,为临床多种输液管路有序管理的实施提供方法和依据。方法对调节器的质地、内径、颜色进行设计。选择需同时使用3根或3根以上延长管且经同一静脉通路泵入的60例患者为研究对象,将其按随机数字表法分为调节器组和未使用调节器组(简称调节器组和常规组),其中调节器组31例,常规组29例,连续观察3d。记录2组延长管发生脱落的次数及护理人员操作错误发生次数,2组相同剂量药物分别以10、25、50ml/h的速率泵入机体所需的平均时长,2组每次随机更换或暂停药物时护理人员所花费的平均时长;调查我科52名护理人员对其临床应用的满意度。结果调节器组更换或暂停药物所发生的差错及管道脱落次数分别为5次和2次,常规组则分别为34次和9次,差异有统计学意义(P<0.05)。调节器组以上述3种不同速率泵入相同剂量的药物所需时间与常规组所需时间比较差异无统计学意义(P>0.05)。调节器组护理人员更换或暂停药物所需的平均时长为(47.05±10.15)s,常规组则为(91.68±13.58)s,差异有统计学意义(t=45.621,P<0.05)。调节器组护理人员在实用性和医疗环境改善得分分别为(93.12±2.79)、(94.71±2.54)分,常规组分别为(91.00±3.86)、(88.06±3.08)分,差异有统计学意义(t=3.199、12.029,P<0.05)。结论与常规组相比,调节器组既可减轻护理人员工作负荷,又不增加其临床使用的危险性。该调节器是一项安全、可靠、便捷的泵用输液管路管理装置。

Objective A practical length regulator of extended tube for microinjection pump was made and its clinical effect was observed.The method and basis were provided for the orderly management of various infusion pipelines in clinic.Methods The texture,inner diameter and color of the regulator are designed.Sixty patients who needed to use three or more lengthened tubes at the same time and were pumped through the same vein passage were randomly divided into two groups:the regulator group and the non-regulator group.31 patients in the regulator group and 29 patients in the routine group were observed continuously for 3 days.During the study period,the number of tube shedding and the number of nursing errors were recorded.The average time required for the same dose of drugs to be pumped into the body was 10 ml/h,25 ml/h and 50 ml/h,respectively.The average time spent by the nursing staff when the drugs were randomly changed or suspended was investigated in 52 cases.Staff satisfaction with its clinical application.Results The number of errors and tube shedding in the regulator group were 5 and 2 times respectively,and 34 and 9 times respectively in the routine group(P<0.05).The time required for the regulator group to pump the same dose at the same rate was 295.33,120.07 and 59.97 seconds,respectively.The time required for the conventional group was 294.63,119.83 and 59.87 seconds,respectively,with no significant difference(P>0.05).The average time needed for drug replacement or suspension was 47.05 seconds in the regulator group and 91.68 seconds in the routine group(P<0.05).The satisfaction of the two groups was 84.98 and 94.5 respectively(P<0.05).Conclusion Compared with the conventional group,the regulator group can reduce the workload of nurses without increasing the risk of clinical use.The regulator is a safe,reliable and convenient pump pipe management device for pumps.
