Trigeminal Cardiac Reflex in Post-Operative Spheno Orbital Menigioma
MetadataShow full item record
The trigeminal cardiac reflex (TCR) is a phenomenon that composed of bradycardia, arterial hypotension, apnoea, and gastric hypermobility. It most occur during skull base surgery at or around struc-tures that are innervated by any sensory branch of the trigeminal nerve. We report a 48-year-old female who was diagnosed of having left spheno orbital meningioma and performed cranio-orbitozigomatic approach to remove the tumor. Six hours post-operative, she had sudden decreased in heart rate 31% decreased from base line, and also mean arterial blood pressure decreased 35% from base line. Laboratory finding was normal, oxygen saturation was 100% and no hypercarbia occurred. She was suspected to have trigeminal cardiac ref-lex. Intravenous administration of atropine abolished the reflex, heart rate and MABP slowly increased to normal. Keywords: Spheno orbital meningioma, Trigeminal cardiac reflex.
