Spinal anesthesia maintains baroreflex stability for hernia repair; confirms no sympathovagal shift despite unpredictable bradycardia risk.
Does bupivacaine-induced spinal anesthesia alter spontaneous baroreflex sensitivity and sympathovagal balance in patients undergoing elective inguinal hernia repair?
Spinal anesthesia does not significantly alter cardiac sympathovagal balance as assessed by spontaneous baroreflex sensitivity, though unpredictable episodes of bradycardia and hypotension may still occur.
Gratadour et al. (1997) studied this question.
