Emergence Delirium in Pediatric Anesthesia

Area of Science:

• Pediatric Anesthesiology
• Neuroscience
• Pharmacology

Background:

• Emergence delirium (ED) is a common postanesthetic complication in children, characterized by agitation and perceptual disturbances.
• Its incidence ranges from 10-80%, causing concern due to risks of self-injury, delayed discharge, and increased healthcare costs.
• The rise in ED correlates with the use of low-solubility inhalational anesthetics like sevoflurane and desflurane.

Purpose of the Study:

• To review predictive factors for emergence delirium in pediatric patients.
• To summarize current evidence on anesthetic agents and adjuncts influencing ED.
• To provide an intervention algorithm for ED prevention and management.

Main Methods:

• Literature review of studies investigating emergence delirium in pediatric anesthesia.
• Analysis of factors contributing to ED, including anesthetic agents, patient characteristics, and procedural elements.
• Comparison of the incidence of ED with different anesthetic techniques and adjunctive therapies.

Main Results:

• Propofol as a single-agent anesthetic is associated with a lower risk of ED compared to sevoflurane-based anesthesia.
• Dexmedetomidine, fentanyl, ketamine, and clonidine show varying effectiveness as adjuncts, with dexmedetomidine being most effective.
• Pain and anesthetic agents are significant contributors, though their cause-effect relationship with ED is debated.

Conclusions:

• Anesthetic choice significantly impacts ED risk, with propofol offering a protective effect.
• Several adjunct medications can effectively mitigate ED, guiding clinical practice.
• Understanding contributing factors and utilizing an intervention algorithm can improve ED management in pediatric patients.
