Objective To explore the value of ultrasound-guided puncture and catheterization of the internal jugular vein in patients with severe trauma. Methods The right internal jugular vein was identified with ultrasound and centered on the screen. Ultrasound-Guided puncture and catheterization of the internal jugular vein was performed in real time after local anesthesia. Results In 50 cases, the success rate of puncture and catheterization at the first attempt was 100% during 1 to 3 min, without any complications including artery injury, hemorrhage, pneumothorax and nerve injury. Conclusion First-aid fast track can save time for emergency operation. Ultrasound-guided techniques can significantly improve the safety and effectiveness of catheterization. Compared with traditional method of anatomy, ultrasound -guided techniques have the significant advantages of improvement of successful rate of first attempt, reduction of the complication and time, which arernthe powerful tool of vascular access, especially for the critically ill.%目的:探讨超声引导技术对严重创伤患者行颈内静脉穿刺置管的应用价值.方法:首先选择并用超声技术定位右侧颈内静脉,局麻后,超声引导直视完成颈内静脉穿刺插管.结果:50例患者均1次穿刺成功并顺利置入中心静脉导管,成功率100％,穿刺时间为1～3 min；无动脉损伤、出血、气胸、神经损伤等并发症.结论:绿色通道手术目的是争取抢救时间,超声引导是提高血管置管安全性和有效性的有效手段.相对于传统的解剖定位法,它可以提高一针到位率、总成功率、降低并发症和减少置管时间,其已成为建立血管通路的有力工具,特别适合应用于危重患者的快速抢救.
