purpose: to evaluate the incidence of the oculo-cardiac reflex (ocr) and its associated risk factors during strabismus surgeries performed at a tertiary referral center between 1390 and 1392. methods: over a 2-year period, all strabismus surgery candidates were enrolled in the study after obtaining consent from the patients or their parents. vital signs were recorded before the initiation of th...

Cardiac arrest is a rare intraoperative complication with few cases reported during neurosurgery. Proposed causes of PEA cardiac in this setting include medications, irrigation, coronary vasospasm, and elicitation the trigeminocardiac reflex.

Our previous studies have shown that the cardiac sympathetic afferent reflex is enhanced in rats with chronic heart failure (CHF) induced by coronary artery ligation and contributes to the over-excitation of sympathetic activity. We sought to determine whether sympathetic activity and cardiac sympathetic afferent reflex were enhanced in adriamycin-induced CHF and whether angiotensin II (Ang II)...

INTRODUCTION The trigemino-cardiac reflex is defined as the sudden onset of parasympathetic dysrhythmia, sympathetic hypotension, apnea, or gastric hypermotility during stimulation of any of the sensory branches of the trigeminal nerve. Clinically, trigemino-cardiac reflex has been reported to occur during neurosurgical skull-base surgery. Apart from the few clinical reports, the physiological ...

We have studied overall reflex control of the circulation by the arterial baroreceptors and cardiac receptors during acute change of blood volume in seven conscious rabbits. A factorial experimental design allowed analysis of the direction, magnitude, and significance of the reflex effects of independent input from each set of receptors, and the reflex interactions when the inputs were combined...

The trigemino-cardiac reflex is a well-known clinical phenomenon described during different craniofacial or skull base surgery as well as neuroradiological interventions and defined as the sudden onset of parasympathetic dysrhythmia, sympathetic hypotension, apnea, or gastric hyper-motility during (intraoperative) stimulation of any of the sensory branches of the trigeminal nerve. According to ...
