purpose: oculocardiac reflex (ocr) is a frequent event during strabismus surgery. the aim of this study is to compare the preventive effect of intravenous lidocaine and hyoscine on ocr.methods: this prospective, randomized clinical trial was performed on 75 patients (5-63 years old) underwent strabismus surgery. patients divided randomly into three groups. intravenous hyoscine (0.2 mg/kg), lido...

A 40-year-old man presented with bradycardia, left eye pain, and intermittent nausea 1 day after blunt trauma to the left orbit. Imaging revealed a large orbital floor fracture with significant herniation of orbital contents but no obvious extraocualar muscle entrapment. Oculocardiac reflex was suspected, and the fracture was repaired surgically within 24 hours of presentation. His bradycardia ...

During strabismus surgery on 81 extraocular muscles in 49 children the cardiac response to calibrated traction on each of the muscles operated on was studied through the use of a microdisplacement transducer and the tachometer of a cardiac monitor. There was no significant difference in the frequency of induction of the oculocardiac reflex between the medial rectus and the other muscles or betw...

abstract oculocardiac reflex (ocr) sometimes occurs as a result of pressure on the eye or traction of the intraorbital surrounding structures during ophthalmic surgery. this can result in bradycardiac arrhythmia and cardiac arrest. a 45-year-old female was undergoing an elective squint correction surgery of one eye under local anaesthesia in a private hospital in december 2013. the patient was ...

Introduction: Dentocardiac reflex, a variant of trigeminocardiac reflex elicited specifically during tooth extraction procedures in dental/maxillofacial surgery and is believed to cause syncope with an afferent link mediated by posterior superior alveolar nerve. Another variant of trigeminocardiac reflex which is also of interest to the oral and maxillofacial surgeon is oculocardiac reflex whic...
