[Comparison of sevoflurane and propofol in combined anesthesia induction with remifentanil for tracheal intubation with fiberoptic bronchoscope].
OBJECTIVE
To compare the effect and hemodynamics of sevoflurane(SEV) and propofol (PRO) in combined anesthesia induction with remifentanil for tracheal intubation fibreoptic bronchoscope (FOB).


METHODS
Twenty-four patients without difficult airway undergoing elective surgery with tracheal intubation general anesthesia were randomly divided into SEV and PRO group. FOB intubation was performed with sevoflurane or propofol administration combined with remifentanil induction. Blood pressure (BP), heart rate (HR), SPO2 and Narcotrend index (NI) were monitored to evaluate the anesthetic depth during the induction. The time to loss of consciousness (LOC), intubation time, intubation score, anesthetic dosage and adverse effects were recorded.


RESULTS
No significant difference was found between the two groups in the time to LOC, intubation time, intubation score, remifentanil dosage. Intubation was performed successfully in both groups. BP and HR of both groups decreased after the induction and did not increase after the intubation, with variation within the normal range. No significant difference in BP and HR was found between the two groups. NI of both groups decreased after the induction and during intubation. NI of SEV group 2 min after intubation was higher than that of PRO group. There was no significant difference in NI between the two groups at the other time points. No significant adverse effects or recall of the intubation procedure were reported.


CONCLUSIONS
Anesthesia induction FOB intubation with sevoflurane and propofol, both in combination with remifentanil, can be applied in surgical patients without contraindications to general anesthesia, and both methods can provide fast induction and good intubation condition with stable hemodynamics.
