Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Anesthesia is essential to control pain and produce unconsciousness during surgery and other procedures during childhood. The anesthetic deepness is measured indirectly through changes in blood pressure and heart rate or can be inferred according to estimated or measured concentrations of anesthetics.

In adults, anesthetic dosing, using patterns based on electroencephalogram (EEG) analysis, has shown clinical advantages compared to traditional monitoring. These advantages include lower consumption of hypnotics, less post-operative cognitive deterioration and decreased intraoperative awakening.

The maturation of the brain and Central Nervous System (CNS) that occurs in childhood affects the response of anesthetics. Additionally, the EEG changes with age and its dominant frequency is lower in children. This explains why brain monitoring methods developed in adults do not work well in children. However, these patterns cannot be extrapolated to the pediatric population. Therefore, it is necessary to develop indexes based on EEG with pediatric data to improve the dosage of hypnotics in this population.

The appearance of alpha wave in frontal EEG has been successfully used as a marker of unconsciousness during general anesthesia with GABAergic hypnotics in adults (sevoflurane, propofol). However, in children, the alpha wave appears since 4 months of age in anesthetics with sevoflurane, so studying the characterization of this wave during the loss and recovery of secondary consciousness anesthetic agents such as propofol has not been studied yet.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Research question:

Is it possible to use the alpha wave as an indicator of loss and recovery of consciousness in anesthesia with propofol in children?

Hypothesis:

The appearance and disappearance of frontal alpha wave is a good indicator of loss and recovery of consciousness in anesthesia with propofol in children.
