Oculocardiac Reflex (Fig. ) The oculocardiac reflex (OCR) is a reflex resulting in severe bradycardia caused by traction applied to the extraocular muscles (especially the medial rectus muscle), pressure on the globe, ocular trauma, traction on the conjunctiva, or occasionally by placement of a retrobulbar block.

The autonomic imbalance between the sympathetic and parasympathetic systems is associated with a variety of stimulations that arise during head and neck surgery.

1 The dysrhythmic response to these stimulations is referred to as the trigeminocardiac reflex(TCR). 2 The oculocardiac reflex (OCR) is a peripheral variant of the TCR and constitutes a dysrhythmic physiological response to physical Cited by: 2. The oculocardiac reflex and sino-atrial arrest.

Can Anaesth Soc J. Mar; 19 (2)– WELHAF WR, JOHNSON DC. THE OCULOCARDIAC REFLEX DURING EXTRAOCULAR MUSCLE SURGERY. Arch Ophthalmol. Jan; – Articles Cited by: The oculocardiac reflex (OCR), which may result from traction or pressure on the globe, orbital contents, or extra ocular muscles, has been associated with cardiac arrests during ocular surgery.

The pathways for this reflex have been established and several preventive methods including retrobulbar block and intravenous injection of atropine have been by: The oculocardiac reflex is a reduction in heart rate associated with traction applied to extraocular muscles and/or compression of the eyeball 13).

Key words: Atropine, cardiac reflex, oculocardiac reflex, skull base surgery, treatment, trigemino Introduction The trigeminal nerve is the largest of the cranial nerves, and The oculocardiac reflex book provides sensory supply to the face, scalp, and mucosa of the nose and mouth.[] Stimulation of the trigeminal receptors that innervate the nose and nasal.

Oculocardiac reflex Incidence 30% to 90%  The oculocardiac reflex is most commonly encountered in pediatric patients undergoing strabismus surgery, although it can be evoked in all age groups and during a variety of ocular procedures,  This reflex consists of a trigeminal (V1) afferent and a vagal (X) efferent pathway.

As the The oculocardiac reflex book reflex is a vagal response, clinicians have attempted to abolish the vagal stimulation of the The oculocardiac reflex book using atropine and gallamine.

Of the two anticholinergic medications used, there appears to be less bradycardia with atropine as opposed to gallamine, The oculocardiac reflex book vs. 5% incidence, respectively.

The physiological response known as oculocardiac reflex identifies a unique decrease in pulse rate associated with any traction of the extraocular muscles or compression of the eyeball itself.

This is particularly relevant to paramedics who are treating a patient The oculocardiac reflex book an injury who becomes bradycardic.

Archives of Neurology and Psychiatry, Volume 1 Full view - Trigeminocardiac Reflex is a comprehensive tutorial reference to the science, diagnosis, and possible treatment of the trigeminocardiac reflex (TCR) that is usually initiated when the trigeminal nerve is disturbed during intercranial surgery.

Since first reported in by co-Editor Bernhard Schaller, the research focused on TCR is expanding. The oculocardiac reflex is a neonatal reflex where pressure on the eyes is sensed by cranial nerve 5 (Trigeminal nerve) to then trigger cranial nerve 10 (Vagus nerve) to start slowing down the heart.

The oculocardiac reflex is an unusual cause of bradycardia due to stimulation of the ophthalmic division of the trigeminal nerve and has been described in a variety of clinical settings.

Trigemino‐cardiac reflex (TCR) is characterized by cardiac arrhythmia, ectopic beats, atrioventricular block, bradycardia, syncope, vomiting, and asystole.

This life‐threatening condition has been documented during simple zygomatic arch elevations, repositioning of blowout and maxillary fractures, orthognathic surgery, and nasoethmoidal fractures [ 32 ].Author: Reza Tabrizi, Hassan Mir Mohammad Sadeghi.

Oculocardiac reflex incidence was 65% during strabismus surgery (34/52), 50% during congenital cataract surgery (4/8), 33% during intramuscular injection of botulinum toxin (1/3), and 0% during. They depend on an intact neural pathway between the stimulation point and a responding organ.

This pathway is called the reflex arc. In a simple reflex this includes a sensory receptor, afferent or sensory neuron, reflex center in the brain or spinal cord, one or more efferent neurons, and an effector organ.

This reflex is known as an Oculocardiac Reflex or the Aschner-Dagnini reflex.

The reflex is mediated by nerve. I do not believe gylcopyrrolate can block the oculocardiac reflex as it is a quaternary amine thus cannot cross the blood/brain barrier. Only teritary amines such as atropine or scopolamine can cross the blood/brain.
