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 1999 by co-Editor Bernhard Schaller, the research focused on TCR is expanding. While its instance is rare, new discoveries are not only increasing diagnosis, but also providing more effective treatment protocols. This text is ideal as a reference for clinical and research neurologists, as a general introduction for clinical presentation, and as a foundation for new research. Represents the first tutorial reference focused on the Trigeminocardiac Reflex (TCR) Content organized by two of the leading scientists in the area, Dr. Tumul Chowdhury (University of Manitoba) and Prof. Bernhard Schaller (University of Southampton) Defines TCR, its onset, and possible treatments Establishes a knowledge base for the future study of the TCR and treatment protocols

The trigemino-cardiac reflex (TCR) is a well established brain-stem reflex and commonly manifests as bradycardia, asystole, hypotension and / or apnea. This phenomenon was extensively explored in the recent past. However, the area related to its exact bio-physiological mechanism, neuro-anatomical linkages, clinical implications, its role in non neurological events and future directions should need to be further investigated. Therefore, this present research topic on TCR would mainly focus on various aspects of TCR and present a comprehensive and exhaustive overview about a phenomena that gains more and more interest during the last few years. Our goal is to present models about the different aspects of the TCR to develop in-depth understanding of TCR.

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 anaesthesia, age (more pronounced in children), the nature of the provoking stimulus (stimulus strength and duration) and different drugs. Already different potential confounders are also identified. This discussion about risk factors has its importance because of the substantial consequences for functional outcome after intraoperative TCR occurrence. But there remains still a substantial lack of thorough understanding of the TCR, the current treatment options for patients with TCR include a mostly empirical approach: (i) risk factor identification and modification; (ii) prophylactic measures of vital signs and (iii) administration of vagolytic agents or sympathomimetics. In this context, we have now created different thinking models so that we can preoperatively plan a skull base surgery procedure safely in relation to a potential occurrence of the TCR episodes. This chapter provides an overview of this unique reflex that presents a unique interaction between heart and brain. In addition, this also illustrates the mechanism of various cardiac rhythm changes related to the TCR.

U2022 Background : Trigeminocardiac reflex occurs after manipulation around any branches of the trigeminal nerve. Oculocardiac reflex has frequently been reported. However, there have been only rare reports of such cases attributed to stimulation of division III. We report a case of trigeminocardiac reflex in open reduction for TMJ dislocation.u2022 Case report : A 74-year-old female presented for TMJ dislocation. Manual reduction was failed because of severe lateral pterigoid muscle contracture. Open reduction under general anesthesia was decided. During surgical manipulation of right mandibular angle, severe bradycardia(HR=20bpm) occurred. Immediately 0.5 mg atropine was administered intravenously, and the surgical manipulation was stopped. After 60 seconds, heart rate normalized. Then, during surgery, severe bradycardia occurred one more time. It disappeared spontaneously as soon as surgical manipulation was stopped. The surgery was completed uneventfully.u2022 Discussion : Trigeminocardiac reflex due to stimulation of division III is very rare. However, given the possibility of profound bradycardia, asystole, or even death when evoked, it is important to be aware of the trigeminocardiac reufb02ex during surgical stimulation of the mandibular divisions of the trigeminal nerve, in particular surgical stimulation of TMJ.u2022 References : William D. Holmes, MD et al. The Trigeminocardiac Reflex and Dermatologic Surgery. Dermatol Surg 2011;37:1795u20131797S. Ron Choi et al. Effects of different anesthetic agents on OCR. J Anesth (2009) 23:489u2013493u2022 Learning points : During TMJ stimulation, it is necessary to deserve attention for trigeminocardiac reflex.

We know a lot of things about cardiac rhythms and their abnormalities, but there are some things that are still waiting to be discovered and, therefore, require more study. In this book, the authors put a little light on those matters, which are not well known yet. The authors have exposed some of such cardiac arrhythmias, especially those affecting the atria of the heart (with special emphasis on fibrillation and flutter atria). By means of this book, readers can broaden their knowledge about this specific topic of supraventricular arrhythmias. They can also find a special chapter on Amiodarone as a cardiac antiarrhythmic drug, which is very revealing, even today.

Ischemic postconditioning is a concept for preventing ischemia/reperfusion injury in cerebral infarction. It has been evolved into experimental research by a broad range of stimuli/triggers and has not yet found its place in translational research. This review, therefore, first examines a potential clinical application of this concept and also provides insight into the phenomenon of trigeminocardiac reflex (TCR) and its oxygen-conserving component as a pillar of the ischemic postconditioning concept in humans. This concept serves as an example that only innovative therapeutic approach will substantially improve the current stroke research.

Functional brain mapping has by now gained a high impact on research and clinical practice: huge funds are unveiled all over the world in order to boost the research and clinical applications of this field of neuroscience. The most successful approach to unlock the mysteries of the brain, to tell it with Jay Ingram, is to bring together an interdisciplinary network of scientists and clinicians and encourage an interchange of ideas. It is this crossfire we try to promote with this book.
