迷你中等长度导管在不同部位置入效果的比较研究

Comparison of the effects of different insertion sites for mini-midline catheters

目的比较迷你中等长度导管在不同部位置入的效果。方法采用定点连续抽样法,选取2023年10月--2024年1月浙江省某三级甲等综合医院收治的130例住院患者作为研究对象。采用简单随机分组法将其分为两组,试验组在上臂置入迷你中等长度导管,对照组在前臂置入。比较两组导管相关并发症发生率、一针穿刺成功率、总穿刺用时、导管相关并发症首次发生时间、因并发症拔管率和导管留置时间。结果121例患者完成研究,其中试验组64例、对照组57例。试验组和对照组的导管相关并发症总发生率分别为29.69%、66.67%;导管相关并发症首次发生时间分别为167(122,220)、104(73,168)h;因并发症拔管率分别为17.19%、42.11%;导管留置时间分别为171(124,258)、120(92,187)h,两组比较,差异均具有统计学意义(P<0.05)。试验组和对照组的一针穿刺成功率分别为96.88%、96.49%;总穿刺用时分别为352(296,446)、370(295,430)s,两组比较,差异无统计学意义(P>0.05)。结论在上臂置入迷你中等长度导管可降低导管相关并发症总发生率、因并发症拔管率,延长导管相关并发症首次发生时间及导管留置时间。

Objective To compare the effects of mini-midline catheters that were placed in different sites.Methods The inpatients of a tertiary general hospital in Zhejiang Province from October 2023 to January 2024 were selected as the study subjects using a fixed point continuous convenience sampling method.The patients were divided into 2 groups by simple random grouping method.The experimental group had a mini-midline catheter placed in the upper arm,and the control group had a mini-midline catheter placed in the forearm.The incidence of catheter-related complications,the puncture success rate with one-attempt,the total procedure time,the time of the first occurrence of catheter-related complications,the rate of removal due to complications,and the indwelling catheter duration were compared between the 2 groups.Results A total of 121 patients were included,including 64 in the experimental group and 57 in the control group.The incidence rates of catheter-related complications in the experimental group and the control group were 29.69%and 66.67%;the times of the first occurrence of catheter-related complications were 167(122,220)h and 104(73,168)h;the rates of removal due to complications were 17.19%and 42.11%;the indwelling catheter duration was 171(124,258)h and 120(92,187)h;the differences between the 2 groups of these outcomes were statistically significant(P<0.05).The puncture success rates with one-attempt in the experimental group and the control group were 96.88%and 96.49%;the total procedure times were 352(296,446)s and 370(295,430)s;the differences between the 2 groups of these outcomes were not statistically significant(P>0.05).Conclusion Mini-midline catheters inserted in the upper arm can reduce the incidence of catheter complications and the rate of removal due to complications,prolong the time of the first occurrence of catheter-related complications and the indwelling catheter duration.
