Abstract:

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.

摘要：

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。
