Table 1

Criteria for inadequate anaesthesia and hypotension or bradycardia.

Inadequate anesthesia
 HypertensionMean blood pressure >120% of baseline or >100 mmHg
 TachycardiaHeart rate >90 beats·min−1
 Somatic arousalCoughing, chewing, grimacing
 Somatic responsePurposeful movement
Hypotension Mean blood pressure <80% of baseline or <60 mmHg
BradycardiaHeart rate <80% of baseline or <45 beats·min−1

Criteria for inadequate anaesthesia were modified based on previous studies.
