Abstract:
Objective To evaluate the effects of different doses of propofol infusion on real-time monitoring of recurrent laryngeal nerve. Method 30 ASA Ⅰ-Ⅱ patients who underwent thyroid gland surgery were given propofol intravenously in different concentrations. BP, HR and real-time monitoring of recurrent laryngeal nerve were recorded with the propofol dosage varying from 3 to 6, 9, 12, 15, 18?g/(kg?min). Results The amplitude of recurrent laryngeal nerve reflex had no change with different doses of propofol infusion. The HR and BP were elevated with low doses of propofol infusion, but there were no changes when propofol concentration was 15 or 18?g/(kg?min). Conclusion Propofol infusion i.v. does not interfere with real-time intraoperative monitoring of recurrent laryngeal nerve, and it does not inhibit the action potential of recurrent laryngeal nerve, but can effectively decrease the cardiovescular reaction.
