静脉置管并发症的超声研究

Rapid diagnosis of venous catheterization complications： an ultrasound imaging study

目的探讨超声成像在静脉置管并发症中的应用价值。方法回顾性分析853例行静脉置管患者术后的超声影像结果，对静脉置管并发症的超声表现及临床疗效进行分析总结。结果超声显像发现静脉置管术并发症主要有导管相关性静脉炎、血栓、机械性并发症等，其中机械性并发症主要有气胸、动脉损伤、血肿等。853例静脉置管术后超声影像结果，出现并发症85例（9．96％），其中静脉炎35例（4．10％）、血栓26例（3．05％）、机械性并发症24例（2．81％）。结论超声显像能无创、有效发现静脉置管的各类并发症，实时超声成像检查可动态监测静脉置管并发症演变过程并能评估治疗效果。

Objective To explore the value of ultrasound imaging in complications associated with venous catheterization. Methods Patients （ n = 853 ） underwent ultrasound imaging examination after ve- nous catheterization. Uhrasonography manifestations of venous catheterization complications and clinical curative effect were analyzed and summarized. Results Phlebitis, thrombus and mechanical complications were found by ultrasound imaging examination. Pncumothorax, hemothorax, arterial puncture and hematoma were among the main mechanical complications. Among the 853 patients, 85 cases （9. 96% ） were found to have complications by ultrasound examination, with 35 cases （4. 10% ） of phlebitis, 26 cases （3.05%） of catheter-related thrombus and 24 cases （2. 81% ） of mechanical complications. Conclusions In summary, a variety of venous catheterization complications can be diagnosed using ultrasound imaging non-invasively, effectively and efficiently. Real-time ultrasound imaging examination can dynamically monitor the development and evolution of venous catheterization complications and effectively evaluate outcomes.
