Severe Bradycardia During Neurosurgical Procedure: Depth of Anesthesia Matters and Leads to a New Surrogate Model of the Trigeminocardiac Reflex
Hemodynamic alterations are observed in various neurosurgical procedures and commonly related to different neurogenic mechanisms. However, anesthetic influences on causation of these perturbations or management are rarely investigated and therefore our present knowledge is still limited.In this case of 43-old Caucasian male, propofol boluses aborted the trigeminal cardiac reflex (TCR) induced s...
متن کاملRapid Spontaneous Coronary Artery Reperfusion Following Severe Bradycardia During Exercise Tolerance Test: A Rare Case Report
The acute occlusion of a coronary artery without the evidence of myocardial infarction might immediately affect both the diagnosis and treatment of coronary artery disease. We present the case with a sudden occlusion of the left main coronary artery without typical chest pain following an exercise tolerance test and rapid spontaneous reperfusion of the left main coronary artery.
متن کاملReflex bradycardia during surgery.
Reflex bradycardia and sinus arrest may occur in a variety of surgical procedures, from neurosurgery to general abdominal, laparoscopic, ophthalmic and facial surgery and even procedures such as liver biopsies and electroconvulsive therapy. In most cases a vagally-mediated reflex has been implicated, although experimental support for this is often lacking. Drugs such as vecuronium, atracurium, ...
متن کاملSevere bradycardia associated with suspension laryngoscopy.
Suspension laryngoscopy is one of the most common procedures performed for visualizing and diagnosing diseases of the larynx. A relatively uncommon yet potentially life-threatening complication is that of severe bradycardia or asystole during manipulation of the larynx. This case report highlights the occurrence of this complication during a routine removal of a true vocal fold lesion at a tert...
متن کاملTemporary severe bradycardia due to pacemaker programming
A 67-year-old male patient received a pacemaker for syncope. His parameters at check-up were: P/R amplitude 2.8/11 mV and atrial/ventricular threshold 0.875/0.625. The pacemaker was programmed as follows: lower rate 60 bpm; upper tracking rate 130 bpm; sensed AV interval 120 ms; paced AV interval 50 ms; atrial/ventricular sensitivity 0.5/5.6 mV, and atrial/ventricular output 2/2 V. Due to synco...
