Total intravenous anaesthesia for direct laryngoscopy: propofol infusion compared to thiopentone combined with midazolam and methohexitone infusion.
Total intravenous anaesthesia for direct laryngoscopy was investigated in 40 patients, randomized into four groups of 10 patients each. First, propofol infusion was compared to thiopentone combined with midazolam. Next, a comparison of propofol infusion with methohexitone infusion was undertaken. The propofol group showed significantly lower peroperative blood pressure compared to the thiopentone/midazolam group. The second propofol group required significantly less alfentanil to stabilize the blood pressure, compared to the methohexitone group. Completeness of recovery, assessed by means of a coin counting test, was faster in the propofol group compared to the thiopentone/midazolam group, while no difference could be demonstrated between the second propofol group and the methohexitone group. It is concluded that propofol seems to be superior to both thiopentone/midazolam and methohexitone with respect to the stability of peroperative blood pressure. Concerning recovery, propofol is superior to thiopentone/midazolam, but offers no advantage over methohexitone.
