BACKGROUND With percutaneous recordings of muscle nerve sympathetic activity (MSA), it is possible to study interactions between the autonomic nervous system and anesthetics. This study describes the effects of propofol infusion both before and during microlaryngoscopy. METHODS Nine patients participated. MSA was recorded, muscle and skin blood flows were measured. Sodium nitroprusside-induced decreases in blood pressure were used to quantitate baroreceptor reflex sensitivity. RESULTS… CONTINUE READING
