- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method the elapsed time after T0 until opening the eyes either spontaneously or upon verbal request repeated every 60 seconds by a blinded investigator.
- Secondary Outcome Measures
Name Time Method •The ET isoflurane, BIS level and minute volume will be observed continuously starting with isoflurane switching off till extubation. The last values before extubation will be recorded. ;•Mean arterial pressure, and heart rate ;•extubation time ;•The elapsed time from T0 to the time the patient stated his/her full name (commands will be given every 20 s by a blinded investigator).;Adverse events: the occurrence of pain, nausea and/or vomiting, shivering, seizures, agitation, and any other adverse event. The visual analog scale (VAS), grading 0 to 10 cm, will be used to evaluate pain (0 = no pain to 10= the most pain I have ever felt) and nausea (0 = no nausea to 10 = as nauseous as I have ever been) during recovery. Pain requiring rescue medications (VAS>4) will be recorded. Agitation will be screened by modified Richmond sedation score
