Insights
Children with developmental disabilities (DD) require similar sedation doses and have comparable adverse event rates as children without disabilities (DN) during brain MRI. This study found no significant differences in medication needs or safety outcomes.
Area of Science:
- Pediatric Anesthesiology
- Developmental Pediatrics
- Neuroimaging
Background:
- Sedation is frequently used for pediatric brain MRI.
- Children with developmental disabilities may present unique challenges during sedation.
Purpose of the Study:
- To compare sedation medication requirements and adverse events in children with and without developmental disabilities undergoing brain MRI.
Main Methods:
- Prospective, observational, age-matched 1:2 case-control study.
- Included children aged 3-10 years sedated for brain MRI.
- Developmental assessment via Vineland Adaptive Behavioral Scale and neurological exam.
Main Results:
- No significant difference in mean doses of pentobarbital, fentanyl, or midazolam between groups.
- Overall adverse event rates were similar (30% in DD vs. 32.9% in DN).
- Hypoxia incidence was comparable (10% in DD vs. 9.3% in DN).
Conclusions:
- Children with developmental disabilities do not require higher sedative doses for brain MRI.
- Incidence of adverse events, including hypoxia, is not increased in children with developmental disabilities compared to their peers.
Objective:
Our objective was to prospectively compare sedation medication requirements and adverse events related to sedation in children with and without developmental disabilities.
Methods:
We conducted a prospective, observational, age-matched, 1:2 case-control study of children (3-10 years) sedated for brain magnetic resonance imaging at a tertiary-care children's hospital. Developmental assessment was performed using the Vineland Adaptive Behavioral Scale and by a pediatric neurologist. Patients were sedated according to institutional sedation protocol. Patient demographics, type and dose of sedation medications, depth of sedation, and adverse events were collected. We defined hypoxia as oxygen saturation 90% or less for 30 seconds or longer and requiring airway maneuvers.
Results:
Seventy children were designated as cases (DD) and 140 as controls (DN). DD had a significantly lower mean Vineland Adaptive Behavioral Scale score than did DN (DD: 62.34 ± 9.70, DN: 103.0 ± 13.71; P < 0.001). A combination of pentobarbital and fentanyl (DD: 32/70 [45.7%], DN: 60/140 [42.9%]) and combination of pentobarbital and midazolam (DD: 28/70 [40%], DN: 43/140 [30.7%]) were the most common sedatives used in both groups. There was no difference in the mean dose of pentobarbital (DD:4.68 ± 1.63 mg/kg, DN:4.67 ± 1.69 mg/kg; P = 0.9), fentanyl (DD: 0.61 ± 0.65 μg/kg, DN: 0.64 ± 0.65 μg/kg; P = 0.7), and midazolam (DD: 0.15 ± 0.17 mg/kg, DN: 0.11 ± 0.14 mg/kg; P = 0.1). There was no difference in the overall adverse events (DD: 30%, DN: 32.9%; P = 0.7) as well as hypoxia (DD: 10%; DN: 9.3%, P = 0.9).
Conclusions:
When compared with DN children, DD children do not require a higher dose of sedatives and do not have a higher incidence of adverse events.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
