Abstract:
Objective To observe the oculocardiac reflex during the ocular plasty and to study its possible mechanism. Methods A total of 132 cases were studied by dynamic electrocardiography to analyze the changing of heart rate before and after operations. Results Heart rate decreasing by over 10 times during operations was regarded as the positive standard of the oculocardiac reflex. Of all cases the oculocardiac reflex appeared in 41 cases and 53 times were observed including of continual two times happened in 6 cases. In all the reflex ,9 cases was observed in injection of anaesthetic, 5 cases in pulling eyelids, the orbicular muscle and the palpabralis muscle, 21 cases in resecting orbital fats,6 cases in stressing the eyeball after operations. The incidence of oculocardiac reflex was 31.1%. Conclusion Some steps in the process in ocular plasty are more possible to elicit the reflex, such as dragging peripheral eyeball muscles,stressing eyeball and pulling eyelid. The reflex will result in heart rate decreasing, heart rhythm and respiratory changing,even render heart to sudden stop . Therefore, we should operate gentlely and accurately,and also avoid overly stress on eyeball to elicit the oculocardiac reflex.
