• Status: Unknown
• Phase: —
• Study type: Observational
• Enrollment: 130 (estimated)
• Sponsor: Catholic University of the Sacred Heart · Academic / Other
• Sex: All
• Age: 18 Years – 70 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this study is 1) to investigate whether the use of BIS as a guide to the administration of inhaled anesthetic (sevoflurane or desflurane) compared with the use of hemodynamic parameters (blood pressure and heart rate) would affect the occurrence of implicit memory and /or dreams recall and 2) to check whether the occurrence of implicit memory and/or dreams recall is related with MAC (Minimal Alveolar Concentration) of inhalational anesthetics and/or preoperative anxiety levels.

Conditions

• Thyroidectomy

Interventions

Type	Name	Description
DRUG	Inhaled anesthetics	Inhaled anaesthetic drugs (sevoflurane or desflurane) concentration will be changed on the basis of hemodynamic parameters (mean arterial pressure and heart rate greater or less than 20% compared to preoperative values).
DRUG	Inhaled anesthetics	Inhaled anaesthetic drugs (sevoflurane or desflurane) concentration will be changed on the basis of Bispectral Index (BIS) value which will be maintained between 40 and 50.
