Summary

Awareness during general anesthesia - that has an incidence between 0.1% and 0.9% of cases and may be more in elderly - remains a concern for anesthesiologists. Awareness experiences range from isolated auditory perceptions to reports of a patient being fully awake, immobilized, and in pain. The isolated forearm technique allows assessment of consciousness of the external world (connected consciousness) through a verbal command to move the hand (of a tourniquet-isolated arm) during intended general anesthesia.

Detailed description

Objective: To compare inhalational induction versus intravenous induction regarding awareness during laryngoscopy and intubation in elderly patients undergoing day case elective surgery.

Conditions

• Awareness, Anesthesia
• Recall Phenomenon
• Inhalation; Gas

Interventions

Type	Name	Description
DRUG	Sevoflurane	IFT response, hemodynamics and BIS value were recorded during intubation period. Then the data acquisition was stopped and the isolated forearm cuff deflated. IFT values were noted by two independent observers
DRUG	TIVA	IFT response, hemodynamics and BIS value were recorded during intubation period. Then the data acquisition was stopped and the isolated forearm cuff deflated. IFT values were noted by two independent observers
