| One minute after intubation | |||
| MAP (mmHg) | 84.9 ± 12.9 | 88.0 ± 15.0 | 0.384 |
| HR (bpm) | 74.1 ± 8.3 | 74.5 ± 10.3 | 0.872 |

| MAP (mmHg) | 105.8 ± 13.9 | 106.5 ± 13.0 | 0.851 |
| HR (bpm) | 78.6 ± 9.6 | 78.6 ± 10.6 | 0.980 |

| MAP (mmHg) | 86.9 ± 10.5 | 88.9 ± 10.2 | 0.449 |
| HR (bpm) | 68.5 ± 9.8 | 68.4 ± 8.7 | 0.978 |
| Haemodynamic events | |||
|
Tachycardia events (N.) (0/1/2/3/4/5) a |
12/7/2/4/5/1 | 13/5/1/5/6/1 | 0.841 |
|
Hypertension events (N.) (0/1/2/3/4/5) a |
8/4/4/8/5/2 | 10/3/3/7/6/2 | 0.591 |
Data are expressed as the frequencies or means ± SDs, as appropriate. Haemodynamic events were defined as an intraoperative increase in HR or MAP greater than 20 % of the baseline value
a Patients with different times of tachycardia events or hypertension events were counted in both groups
