摘要
目的探讨桡动脉穿刺及置管引起的短期内血流动力学变化。方法对30例接受择期手术需要进行桡动脉穿刺置管的患者,应用彩色多普勒超声于穿刺前、导管拔除后30 min、导管拔除后24 h观察患者尺、桡动脉峰值流速并进一步比较尺动脉与桡动脉峰值流速的比值。结果桡动脉穿刺置管引起动脉血流显著变化,穿刺侧尺动脉与桡动脉收缩期峰值流速的比值在导管拔除后30 min及24 h均较穿刺前明显增加(均P<0.05),没有相关临床并发症发生。结论彩色多普勒超声能明确观察桡动脉血流并能实时测得各项数据,穿刺侧动脉压监测在一定时间内引起相关动脉显著的功能性变化。
Objective To examine the possible local damaging effects of arterial monitoring catheters on arterial functioning in patients after elective surgery with color Doppler ultrasound. Methods Thirty patients who underwent elective surgery with a radial artery catheter were examined. The 2-dimentional ultrasonography and the blood flow of each radial and ulnar artery were examined before the puncture, 30 minutes and 24-hour after removal. Artery diameter, peak velocity of blood flow and patency were examined. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were compared. The non-affected arm was used as the control. Results Artery monitoring catheters caused a remarkable functional arterial change in the affected arm. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were increased 30 minutes and 24 hour after removal. There were no severe clinical complications. Conclusion Radial artery blood flow can be observed clearly with color Doppler ultrasound. Aseries of data were measured and recorded. There is significant change in the hemodynamic function of the artery during certain period of time.
