目的研究眼睑手术中心脏反射发生的机制。方法对３５例眼睑手术病人术中进行持续心电图监测，并与术前基础值进行比较。结果３５例眼睑手术病人中，４例注射局麻药时发生眼心反射，１３例在术中手术操作时发生眼心反射。眼心反射发生率为４８．６％。结论眼心反射是由于压迫眼球，通过迷走神经反射所致。可引起心率减慢、心脏节律和呼吸的改变，甚至可引起心跳骤停。对于眼睑手术病人应注意监测和防治眼心反射 Objective To study the mechanism of cardiac reflex in eyelid surgery. Methods Thirty-five patients with eyelid surgery underwent continuous electrocardiogram (ECG) during operation and compared with preoperative baseline values. Results Among the 35 patients with eyelid surgery, 4 received ophthalmocentrism during the injection of local anesthetic, and 13 received ophthalmocentric reflex during operation. Ocular heart reflex incidence was 48.6%. Conclusion Ocular heart reflex is due to oppression of the eye, caused by vagal reflex. Can cause slow heart rate, heart rhythm and breathing changes, and even can cause sudden cardiac arrest. Patients with eyelid surgery should pay attention to monitoring and prevention of eye reflex
