目的:研究经皮冠状动脉(PCI)介入治疗中拔鞘管时发生心血管迷走反射的预防及处理。方法:将进行冠脉介入治疗的冠心病患者513例分为两组,预防组260例,在拔管前采用静脉滴注的方式给予0.9%氯化钠注射液约300mL,在拔管时使用2%利多卡因局部麻醉股动脉穿刺点周围;对照组253例,直接拔下鞘管。结果:预防组发生迷走反射3例(1.15%),对照组发生迷走反射17例(6.72%),两组比较差异具有统计学意义(P<0.05)。结论:采用有效的预防处理可以防止冠心病介入治疗术后迷走反射情况的出现,能够提升冠心病介入治疗的成功率。
Objective: To study the prevention and treatment of cardiovascular vagal reflex during percutaneous coronary intervention (PCI). Methods: 513 patients with coronary artery disease undergoing coronary intervention were divided into two groups: prevention group (260 cases), intravenous infusion of 0.9% sodium chloride injection (300mL) before extubation, and extubation 2% lidocaine local anesthesia around the femoral artery puncture point; control group 253 cases, the direct removal of the sheath. Results: There were 3 cases (1.15%) in the prevention group and 17 cases (6.72%) in the control group. The differences between the two groups were statistically significant (P <0.05). Conclusion: The effective preventive treatment can prevent the occurrence of vagal reflex after interventional treatment of coronary heart disease and improve the success rate of interventional therapy of coronary heart disease.
