[Awareness: a problem in paediatric anaesthesia?].

Area of Science:

• Anesthesiology
• Pediatric Medicine
• Neuroscience

Context:

• Intraoperative awareness occurs more frequently in pediatric patients (0.8-5.0%) compared to adults (0.1-0.2%).
• The consequences of intraoperative awareness in children are not well-studied, unlike in adults.
• Causes include intentional light anesthesia, inadvertent underdosing, and equipment or human error.

Purpose:

• To highlight the challenges in pediatric anesthesia dosing due to significant pharmacokinetic and pharmacodynamic changes from preterm infants to adolescents.
• To emphasize the need for better understanding of drug characteristics in different pediatric age groups.
• To advocate for improved intraoperative awareness prevention strategies in children.

Summary:

• Pediatric intraoperative awareness is a significant concern, potentially more prevalent than in adults.
• Accurate anesthetic dosing is complex in children due to wide-ranging pharmacokinetic and pharmacodynamic variability.
• Painful procedures may be performed without adequate analgesia in young children.
• Monitoring tools like the bispectral index can aid in assessing hypnotic depth.

Impact:

• Improved knowledge of pediatric drug pharmacokinetics and pharmacodynamics is crucial for reducing awareness incidence.
• Enhanced vigilance in daily anesthetic care is essential.
• Increased use of advanced monitoring techniques, such as the bispectral index, can further decrease intraoperative awareness in pediatric patients.
• Further research is needed to fully understand and mitigate the consequences of intraoperative awareness in children.
