BACKGROUND The current study aimed to determine preventive effect of 2 percent topical xylocaine on oculocardiac reflex in ophthalmological surgeries except strabismus, including retinal detachment and vitrectomy with scleral buckling under general anesthesia. METHODS A randomized controlled clinical trial was carried out on 150 patients aged 18-90 years undergoing ophthalmological surgeries ...

Three case reports are presented to illustrate the existence and importance of reflex bradycardic responses that can occur during maxillofacial surgical procedures. All three patients were healthy young adults undergoing operations which did not include any manipulation of orbital structures. After the patients had been anaesthetized for some time and were haemodynamically stable, profound brad...

BACKGROUND Profound bradycardia during eye surgery is potentially serious event. In clinical practice this Oculocardiac Reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of anticholinergic premedication (atropine) to prevent OCR. METHODS This study comprises of sixty patients (age 2-30 years) oper...

This issue includes a study (Haneef et al. 2008) of simulated ocular compression (OC) by physicians who “routinely” performed OC during EEG examinations when syncopal episodes including breath-holding spells were suspected. The authors found that though each of those three physicians exerted a different range of pressure on a sphygmomanometer cuff when asked to use their thumbs as if the inflat...
