Abstract

Bezold-Jarisch reflex is a reflex that may occur during regional anesthesia, upper-extremity blocks and sometimes in general anesthesia, resulting in hypotension, bradycardia, apnea or cardiac arrest elicited by chemical or mechanical receptor stimulations. This reflex mostly occurs in the sitting position during upper-extremity nerve blocks can be forgotten in other complications. The complications that occurred after this reflex can be overcome by taking necessary precautions and providing sufficient cardiac monitorization. In our cases to be presented, we want to remind you of Bezold-Jarisch reflex, which may cause severe complications when forgotten.
