Bispectral Index to Guide Intubation in Pediatric Anesthesia

Use of Bispectral Index to Guide Intubation During Sevoflurane Anesthesia in Children

This prospective study aimed to determine the minimal level of Bispectral index needed for quality laryngoscopy before ear, nose and throat surgery in children.

• Children will received intra-rectal premedication based on midazolam 0.4mg
• Children will be monitored according to standard guidelines
• One blinded anesthesiologist will be in charge of anesthesia induction and the other one will be in charge of data collection (end tidal sevoflurane concentration, sevoflurane minimal alveolar concentration, bispectral index) and guidance of induction according to the predetermined bispectral index (up and down allocation)

Inclusion Criteria:

• American Society Anesthesiology physical status classification system :1 or 2
• scheduled ear, nose and throat surgery in a one day program
• oral intubation required

Exclusion Criteria:

• parents refusal
• recent respiratory infection
• epilepsy
• suspected difficult intubation
