What factors predict delayed behavior problems in children after procedural sedation

Predictors of Maladaptive Behaviors in Children Undergoing Procedural Sedation

Observational London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT07495826

This study will test which factors make children aged 1–17 more likely to have delayed behavior problems (such as sleep trouble, anxiety, or aggression) after procedural sedation in emergency departments and dental clinics.

What this trial studies

This is a multicentre observational study enrolling children aged 1–17 who receive procedural sedation or anxiolysis in emergency departments and dental clinics. Researchers will collect baseline measures including pre-sedation anxiety, pain, and temperament, and record sedative agents used. Caregivers will be contacted after the procedure (including via SMS) to track delayed maladaptive behaviors for up to two weeks and to measure post-sedation pain. The study will model which factors are associated with an increase in negative behaviors and estimate the proportion of children affected.

Who should consider this trial

Good fit: Children and adolescents aged 1–17 undergoing procedural sedation or anxiolysis in participating emergency departments or dental clinics whose caregivers can complete follow-up (English or French as applicable) and have a smartphone for SMS follow-up are ideal candidates.

Not a fit: Children whose caregivers lack the required language comprehension, do not have a smartphone for SMS follow-up, cannot complete planned follow-up, or who have been previously enrolled are unlikely to be eligible or to directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help clinicians identify children at higher risk for delayed behavioral problems and provide targeted support to reduce symptoms and family disruption.

How similar studies have performed: Small prior studies and literature from inhalational anesthesia have suggested links between younger age, pre-procedural anxiety, and maladaptive behaviors, but evidence is limited and this larger multicentre effort aims to confirm those findings.
