Abstract

Background: Oculocardiac reflex (OCR) is a cardiac manifestation that accompanies physical stimulation of the eye during various ocular surgeries and may be potentially life threatening. The purpose of this study is to investigate the incidence and risk factors of OCR during cataract surgery. Methods: Adult patients who were planned to undergo cataract surgery under local anaesthesia were enrolled in to the study. Heart rate (HR) and mean arterial blood pressure (MAP) were measured at baseline and at various steps during the surgery. The parameters including various demographic characteristics were compared between patients with and without OCR. Results: One hundred and thirty-six patients (60 males and 76 females) were recruited. Out of them, 49 patients (36.03%) underwent phacoemulsification and 87 (63.97%) patients underwent manual small incision cataract surgery. OCR was noted in 22 (16.18%) patients. Age, presence of co-morbidities and baseline MAP were found to be significantly associated with OCR. Baseline characteristics like gender, HR and duration of surgery were comparable between both the groups. Conclusion: OCR can occur at various steps during cataract surgery under peribulbar block.

白内障手术中眼心反射的发生率及危险因素的前瞻性观察研究
背景:眼心反射(OCR)是一种心脏表现,在各种眼科手术中伴随着眼睛的物理刺激,可能会危及生命。本研究旨在探讨白内障手术中OCR的发生率及危险因素。方法:选取拟行局部麻醉白内障手术的成年患者作为研究对象。心率(HR)和平均动脉血压(MAP)在基线和手术期间的各个步骤测量。比较有OCR和无OCR患者的各种人口学特征参数。结果:共纳入136例患者(男60例,女76例)。其中49例(36.03%)行超声乳化术,87例(63.97%)行人工小切口白内障手术。22例(16.18%)患者出现OCR。发现年龄、合并症的存在和基线MAP与OCR显著相关。两组患者的性别、HR和手术时间等基线特征具有可比性。结论:眼球周围阻滞下白内障手术的不同阶段均可发生OCR。
