目的探讨血管迷走反射的发生特点及防治措施。方法总结468例患者,分析血管迷走反射的发生特点。结果468例发生此血管迷走反射14例,其中冠状动脉造影术2例,PTCA术、STENT术12例;局部血肿发生5例;拔管压迫止血时发生10例,拔管后30min内发生3例,2h内发生1例。结论冠状动脉造影和经皮腔内冠状动脉成形术(PTCA)、支架术(STENT)已成为冠心病诊断和治疗的重要手段。在拔除动脉鞘后患者常发生拔管后迷走反射并发症,出现心动过缓、低血压甚至休克,发生迅速且后果严重,需注意避免各种诱因,确诊后立即行相应的急诊处理。
Objective To investigate the occurrence and prevention and treatment of vasovagal reflex. Methods 468 patients were summarized, the characteristics of vasovagal reflex were analyzed. Results 468 cases of vasovagal reflex occurred in 14 cases, including coronary angiography in 2 cases, PTCA surgery, STENT surgery in 12 cases; local hematoma occurred in 5 cases; extubation oppression hemostasis occurred in 10 cases, 30 minutes after extubation occurred in 3 cases , 1 case occurred in 2h. Conclusions Coronary angiography and percutaneous transluminal coronary angioplasty (PTCA) and stenting (STENT) have become an important method of diagnosis and treatment of coronary heart disease. In the removal of arterial sheath patients often occur after extubation vagal reflex complications, there bradycardia, hypotension and even shock, rapid and serious consequences, should pay attention to avoid a variety of incentives, the diagnosis immediately after the appropriate emergency treatment.
