Effect of Anesthesia Induction on Cerebral Hemodynamic in Children

Effect of Anesthesia Induction on Cerebral Hemodynamic in Children

General anesthesia induces hemodynamic changes, notably a reduction of arterial blood pressure going up to 30%, that may impact cerebral perfusion and oxygenation.The purpose of this study is to assess the impact of anesthesia on the cerebral oxygenation, the perfusion of the brain (assessed with transcranial doppler), and the depth of anesthesia in children between 6 months and 5 years old during the induction of general anesthesia (induced with sevoflurane and/or IV agents). It is expected that the cerebral hemodynamic will be maintained despite systemic variations.

Inclusion Criteria:

• General anesthesia for elective surgery
• American Society of Anesthesiologists score 1 and 2
• Written informed consent obtained from the parents or legal tutors.

Exclusion Criteria:

• 3 unsuccessful attempts of IV access
• ultrasound device non available
• neurologic comorbidity
