Methods: 40 ASAI-II adult patients without cardiac system diseases undergoing elective suspension laryngoscopy were randomly divided into two groups. After induction with midazolm, propofol, fentanyl and succinylcholine, tracheal intubation was performed. In group I, anesthesia was maintained with propofol infusion and respiration was controlled by jet ventilation with ordinary frequency. In group II anesthesia was maintained with isoflourane and nitrous oxide and respiration was controlled by IPPV. SBP, DBP, HR, ECG and SPO2 were monitored during operation. Results: Changes of SBP, DBP, HR and cardiovascular responses in group I were greater than group II (p<0.05). Patients in group II awaked more rapidly than that in group I. Conclusion: Intravenous induction combined with inhalation maintenance was an ideal anesthetic method for laryngeal microsurgery.
