Helpful for pediatric eye surgery,1 when combined with fentanyl and ketamine, intravenous dexmedetomidine may decrease oculocardiac reflex.2 From 2013 to 2015, in our institutional revi...

A.A TAHER,

Three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. Many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. This manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated...

profound bradycardia during eye surgery is a potentially serious event. in clinical practice oculo-cardiac 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 ketamine as an induction drug and anticholinergic premedication (atropine) to prevent ocr. this study comprised 90 patients (aged 4-10 years...

BACKGROUND AND OBJECTIVES Strabismus surgery is a frequently performed pediatric ocular procedure. A frequently occurring major problem in patients receiving this treatment involves the oculocardiac reflex. This reflex is associated with an increased incidence of postoperative nausea, vomiting, and pain. The aim of this study was to investigate the effects of a sub-Tenon's block on the oculocar...

The present study was conducted to observe the effect of graded mechanical stimuli on occurrence of oculocardiac reflex (OCR). The experiments were carried out in twenty albino rabbits of either sex weighing between 1-2 kg. Changes in heart rate and/or cardiac rhythm (oculocardiac reflex) were studied by applying traction with progressively increasing weights to medial rectus muscle. Mean thres...

An oculocardiac reflex is sometimes elicited by pressure on the eye or traction of the intraorbital surrounding structures during ophthalmic surgery(,'#", or orbit-facial trauma&". The afferent arc of the oculocardiac reflex reaches the brain stem via the nasocilliary nerve'!". Here is reported, what we believe to be the first case where catheterization of the ophthalmic artery elicited an ocul...

The oculocardiac reflex during strabismus surgery has generally been regarded as a hazard capable of causing death. Six cases are presented which show a beneficial use of the oculocardiac reflex. Isolation of a previously slipped or 'lost' extraocular muscle can be difficult. In this series identification of the tissue as muscle was substantiated by observing a positive oculocardiac reflex when...
