In terms of spontaneous breathing, the median recovery time was:
for patients with propofol, 1.5 minutes (range: 0.33 - 5.5) with EEG and 3.0 minutes (range: 0 - 10.25) without EEG;
for patients with sevoflurane, 2.0 minutes (range: 0 - 8.5) with EEG and 3.5 minutes (range: 0 - 10.0) without EEG.
With respect to extubation, the median recovery time was:
for patients with propofol, 2.75 minutes (range: 1.0 - 8.0) with EEG and 7.0 minutes (range: 2.0 - 14.75) without EEG;
for patients with sevoflurane, 3.0 minutes (range: 1.33 - 13.0) with EEG and 4.0 minutes (range: 1.0 - 13.0) without EEG.
In terms of eye opening, the median recovery time was:
for patients with propofol, 3.0 minutes (range: 1.0 - 8.0) with EEG and 9.125 minutes (range: 2.0 - 22.0) without EEG;
for patients with sevoflurane, 3.42 minutes (range: 1.0 - 13.0) with EEG and 6.63 minutes (range: 1.0 - 13.0) without EEG.
In terms of orientation, the median recovery time was:
for patients with propofol, 6.0 minutes (range: 2.0 - 15.0) with EEG and 14.0 minutes (range: 5.0 - 52.0) without EEG;
for patients with sevoflurane, 6.5 minutes (range: 3.0 - 63.0) with EEG and 9.5 minutes (range: 2.0 - 19.0) without EEG.
Monitoring significantly reduced the recovery time in the group of patients anaesthetised with propofol. In the case of sevoflurane, the recovery time was lower for patients that were monitored than those that were not monitored, but the difference did not reach statistical significance.
