Insights
Intravenous methohexital effectively sedated children for emergency CT scans. This short-acting medication proved safe and efficient in a pediatric setting.
Area of Science:
- Pediatric Emergency Medicine
- Pharmacology
- Radiology
Background:
- Sedation is often necessary for pediatric patients undergoing emergency computed tomographic (CT) scans.
- Rapid and safe sedation is crucial in emergency settings to facilitate timely diagnostic imaging.
Purpose of the Study:
- To assess the efficacy and safety of intravenous methohexital for sedating children during emergency CT scans.
Main Methods:
- A case series design was employed in a pediatric emergency department.
- Data were collected on 55 patients receiving intravenous methohexital for sedation during CT scans.
- Key data points included demographics, dosage, sedation duration, and observed outcomes and complications.
Main Results:
- Methohexital was administered at doses ranging from 0.5 to 2.0 mg/kg (mean 1 +/- 0.5 mg/kg).
- The onset of sedation was rapid (mean 1 +/- 0.4 minutes), with a brief duration (mean 12 +/- 5 minutes).
- The drug's effects lasted approximately 14 +/- 6 minutes, with effective sedation achieved in most patients and minimal complications.
Conclusions:
- Intravenous methohexital is a safe and effective short-acting sedative for pediatric patients requiring emergency CT scans.
- Its rapid onset and brief duration make it suitable for use in pediatric emergency departments.
Objective:
To evaluate the effectiveness and safety of intravenous methohexital as a sedative in children undergoing emergency computed tomographic scans.
Design:
Case series.
Setting:
An urban pediatric emergency department at a level I trauma center.
Participants:
Patients receiving intravenous methohexital for sedation to undergo emergency computed tomographic scans.
Methods:
Descriptive data were generated, including demographics, doses administered, times of sedation, outcomes, and complications.
Results:
Data are reported from a total of 55 patients. The doses administered ranged from 0.5 mg/kg to 2.0 mg/kg (mean +/- SD, 1 +/- 0.5 mg/kg). Onset of sedation was rapid (mean +/- SD, 1 +/- 0.4 minutes), sedation was brief (mean +/- SD, 12 +/- 5 minutes), and the mean +/- SD length of the drug's effects was 14 +/- 6 minutes. Sedation was effective in most cases, and only a few patients had complications.
Conclusion:
Intravenous methohexital is a short-acting and effective sedative for use in pediatric emergency departments to obtain computed tomographic scans.

Sedatives and Hypnotics Drugs: Barbiturates
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...
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...
