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...

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...

A case of bradycardia is reported which was precipitated by cold normal saline applied to the eye during general anaesthesia. The history and physiology of the diving reflex is discussed and we believe that these data suggest that this patient's bradycardia was induced by the diving reflex, and not by the oculocardiac reflex.
