The Observer's Assessment of Alertness/Sedation (OAA/S) scale aligns with Bispectral analysis (BIS) values in pediatric procedural sedation. This correlation holds true for non-ketamine medications but not for ketamine.

Area of Science:

  • Anesthesiology
  • Pediatric Sedation
  • Neurophysiology

Background:

  • Bispectral analysis (BIS) uses EEG data to quantify sedation levels (0-100).
  • Assessing sedation depth in pediatric patients is crucial for procedural safety.
  • Clinical sedation scales, like OAA/S, are commonly used but their agreement with BIS needs evaluation.

Purpose of the Study:

  • To determine the agreement between clinical sedation scales and BIS values in pediatric patients undergoing procedural sedation.
  • To investigate if the OAA/S scale can predict BIS values in this population.

Main Methods:

  • 47 pediatric patients (ages 2-17) undergoing procedural sedation were enrolled.
  • BIS monitoring was used alongside the Observer's Assessment of Alertness/Sedation (OAA/S) scale, assessed every 5 minutes.

  • Longitudinal regression analysis examined the association between OAA/S scores and BIS values.

    • Main Results:

    • A significant association was found between OAA/S scores and BIS values (P < 0.0001).
    • This association was significant for patients sedated with non-ketamine medications (P < 0.0001).
    • The association was not statistically significant for patients sedated with ketamine (P = 0.09).

    Conclusions:

    • The OAA/S sedation scale can predict BIS values in pediatric patients.
    • This prediction is reliable when using certain sedative medications, excluding ketamine.
    • BIS monitoring may enhance sedation assessment in pediatric procedural sedation.
