目的:探讨在超声引导下改良Seldinger技术行外周静脉置入中心静脉导管(PICC)的临床应用价值。方法:选择我院住院需行PICC置管的患者300例作为观察对象,随机设为观察组(150例)和对照组(150例)。观察组患者采用超声引导下改良Seldinger技术行PICC置管,对照组采用传统穿刺法进行PICC置管。观察记录2组贵要静脉使用情况、导管末端位置、留置时间、并发症发生情况,评价2组穿刺、置管的一次性成功率。结果:观察组一次性穿刺成功率99.3%(149/150),一次性置管成功率98.7%(148/150),总置管成功率100%,贵要静脉使用率95.3%(143/150),导管末端位于上腔静脉的比例94.7%(142/150),均显著高于对照组(均P<0.05);观察组导管留置时间(151±17)d亦明显较对照组延长(P<0.05);观察组静脉血栓、机械性静脉炎及周围组织损伤的发生率均显著低于对照组(均P<0.05),穿刺点渗血及导管相关感染发生率比较,两组无显著差异性。结论:PICC置管在超声引导下应用改良Seldinger技术,可显著提高置管成功率,具有较高的临床应用价值。
Objective: To investigate the clinical value of peripheral venous catheterization (PICC) with modified Seldinger technique guided by ultrasound. Methods: A total of 300 patients undergoing PICC catheterization in our hospital were selected as observational subjects and randomly assigned to observation group (150 cases) and control group (150 cases). Patients in the observation group underwent PICC catheterization with modified Seldinger technique under ultrasound guidance and PICC catheterization in the control group by traditional puncture method. Observe and record the use of two groups of your vein, catheter end position, indwelling time, the incidence of complications, evaluation of two groups of puncture, catheter one-time success rate. Results: The successful rate of one-time puncture in the observation group was 99.3% (149/150), the success rate of one-time catheterization was 98.7% (148/150), the total success rate of catheterization was 100% and the rate of intravenous venous use was 95.3% (143/150 ) In the superior vena cava and 94.7% (142/150) in the superior vena cava, respectively, which were significantly higher than those in the control group (all P <0.05). The indwelling time of the catheter in the observation group (151 ± 17) d was also significantly longer than that of the control group <0.05). The incidences of venous thrombosis, mechanical phlebitis and surrounding tissue injury in the observation group were significantly lower than those in the control group (all P <0.05). There was no significant difference between the two groups in the incidence of bleeding and catheter-related infection Sex. Conclusion: The application of modified Seldinger technique under the guidance of ultrasound can significantly improve the success rate of catheterization and has a high clinical value.
