眼心反射是指压迫眼球或牵引眼肌等情况下引起心率减慢的一种反应。它首先由 Aschner 和 Dagnine 在1908年分别报道。此后有多位学者对此进行观察

并有报告发生心搏停止

甚至死亡的病例。例如 Kirsch 的一例视网膜脱离手术患者

在处理眼外肌后不久

就心搏停止而死亡。Mallinson 也报告一3岁幼儿行眼肌退后和缩短时

心搏停止而死亡。足见此反射有其重要性。我们观察了52例斜视患者手术中的心率改变

比较针麻和药麻时的反应

部分作了心电图描绘。报道如下:The heart-rate was taken for 52 patients undergoing strabismus surgery(26 cases by acupunctureand 26 cases by local anesthesia)at the following steps:incision of conjunctiva

separation of subcon-junctival tissue

hooking of muscle

division of check ligament

suturing of muscle and severing ofmuscle.A lowering of heart-rate over 10 beats/min.was considered to be a positive oculocardiac re-flex.In a total of 52

73.8%showed a positive reflex;in terms of 90 muscle manipulations positivereflex appeared in 60%;no significant difference was found between the acupuncture and local anes-thetic groups.The heart-rate of the acupuncture group generally showed a smaller decrease for allsteps

but there was no significant statistical difference.Both groups showed a most significant drop of heart-rate and highest incidence of positive reflexduring the hooking of muscles.Maneuvering of the internal rectus elicited a higher positive reflexthan the external rectus;the inferior oblique

superior and inferior recti also ga a high incidence of reflex.No significant difference was noted between recession and resection

or the sequence ofmuscle manipulaion.
