Abstract :

Background:

This randomized study was conducted to compare the hemodynamic changes and emergence characteristics of sevoflurane versus propofolanesthesia for microlaryngealsurgery.

Methods:

Sixty geriatrics patients age between 65–75 years, undergoing microlaryngeal surgery were randomly allocated into two groups. In propofol group, anesthesia was induced with 1–2mg/kg propofol and maintained with propofol infusion 50–200 μg/kg/h. In sevoflurane group induction was carried out with 4–8% sevoflurane and maintained with sevoflurane in nitrous oxide and oxygen. The propofol and sevoflurane concentrations were adjusted to maintain the bispectral index between 40–60. All patients received fentanyl 2 μg/kg before induction and succinylcholine 1 mg/kg to facilitate tracheal intubation. The hemodynamic changes during induction and suspension laryngoscopy were compared. In addition, the emergence time, time to extubation, and recovery were assessed.

Results:

The changes in heart rate were comparable. The mean arterial pressure was significantly lower after induction and higher at insertion of operating laryngoscope in propofol group as compared to sevoflurane group. More patients in propofol group had episodes of hypotension and hypertension than sevoflurane group. The emergence time, extubation times, and recovery time were similar in both groups.

Conclusion:

We found that sevoflurane showed advantage over propofol in respect of intraoperative cardiovascular stability without increasing recovery time.
