Trigeminocardiac reflexes: maxillary and mandibular variants of the oculocardiac reflex.
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...
متن کاملEye hue and the oculocardiac reflex.
During operations for squint nodal rhythm and other more serious arrhythmias such as heart block and multifocal ventricular extrasystoles, as well as the oculocardiac reflex, are shown to occur more frequently in patients with brown or hazel eyes than in patients with blue or grey eyes.
متن کاملThe oculocardiac reflex in strabismus surgery.
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...
متن کاملTrigeminocardiac Reflex by Mandibular Extension on Rat Pial Microcirculation: Role of Nitric Oxide
In the present study we have extended our previous findings about the effects of 10 minutes of passive mandibular extension in anesthetized Wistar rats. By prolonging the observation time to 3 hours, we showed that 10 minutes mandibular extension caused a significant reduction of the mean arterial blood pressure and heart rate respect to baseline values, which persisted up to 160 minutes after ...
متن کاملThe Trigeminocardiac Reflex — An Example of Reflexive Heart Rhythm Change
The trigeminocardiac reflex (TCR) is defined as the sudden onset of parasympathetic dysrhythmia, sympathetic hypotension, apnoea or gastric hyper-motility during mechanical/thermal stimulation of any of the sensory branches of the trigeminal nerve. The risk factors that are already known for increasing the prevalence of the TCR include anatomical location, hypercapnia, hypoxemia, light general ...
