摘要
目的探究等腰直角三角形定位结合三次回血法在上臂超声引导下迷你中线导管置管中的应用价值,为临床实践提供参考。方法将176例神经内科老年患者随机分为对照组和观察组各88例。对照组采用传统超声引导置管技术置管,观察组采用等腰直角三角形定位结合三次回血法置管。比较两组的一次穿刺成功率、穿刺时间、穿刺并发症及导管留置期间并发症发生率、留置时间。结果两组各84例完成研究。观察组一次穿刺成功率为95.24%,显著高于对照组的83.33%(P<0.05)。观察组穿刺时间显著短于对照组,留置时间显著长于对照组,穿刺中送管困难、血肿发生率及导管留置期间并发症(静脉炎、导管相关性血栓、输液不畅)发生率显著低于对照组(均P<0.05)。结论等腰直角三角形定位结合三次回血法穿刺技术可显著提高迷你中线导管一针穿刺成功率,降低穿刺和留置期间并发症,延长导管留置时间。
Objective To explore the value of the isosceles right triangle principle combined with the triple blood flashback method for ultrasound-guided mini-midline catheter insertion in the upper arm,aiming to provide guidance for clinical practice.Methods A total of 176 elderly patients from the neurology department were randomly assigned to either a control group(n=88),receiving traditional ultrasound-guided mini-midline catheter insertion,or an observation group(n=88),receiving catheter insertion using the isosceles right triangle principle combined with the triple blood flashback method.One-attempt success rate,puncture time,incidence of puncture complications,incidence of complications during duration of catheter use,and catheter dwell time were compared between the two groups.Results Eighty-four patients in each group completed the study.The one-attempt success rate in the observation group was 95.24%,significantly higher than that in the control group(83.33%,P<0.05).The observation group showed significantly shorter puncture time,longer catheter dwell time,lower incidence of difficult catheter advancement and hematoma during puncture,as well as lower incidence of complications(phlebitis,catheter-related thrombosis,infusion difficulty),compared to the control group(all P<0.05).Conclusion The puncture technique using the isosceles right triangle principle combined with the triple blood flashback method can significantly improve the one-attempt success rate of mini-midline catheter insertion,reduce complications during puncture and use of the catheter,and prolong catheter dwell time.
