Abstract

The following report describes the occurrence of severe hypotension and bradycardia in a healthy 50-year-old man following placement from supine to the beach chair position during general anesthesia for injured rotator cuff tendon repair, as well as the occurrence of micturition syncope in a 71-year-old man following postobstructive diuresis after combined spinal–epidural anesthesia for total knee replacement. Rapid decompression of the urinary bladder is associated with severe hypotension, bradycardia, and syncope. Neurally mediated syncope includes true vasovagal and situational syncope that can occur in association with various situations such as cough, micturition, postprandial state, and interscalene block. We report two cases of neurally mediated syncope (true vasovagal and situational) that occurred in different conditions and were controlled well with prompt and proper management without serious complications.
