Insights
Chloral hydrate is a safe and effective sedative for infant pulmonary function tests. Strict adherence to dosage and contraindications, along with trained monitoring, ensures patient safety during these procedures.
Area of Science:
- Pediatric Pulmonology
- Clinical Pharmacology
Background:
- Pulmonary function tests (PFTs) in infants require effective sedation.
- Chloral hydrate is commonly used for procedural sedation in pediatric populations.
Purpose of the Study:
- To evaluate the efficacy and safety of chloral hydrate for sedating infants undergoing PFTs.
- To identify potential complications associated with chloral hydrate sedation in this age group.
Main Methods:
- Retrospective analysis of sedation attempts for PFTs in infants from June 2007 to August 2014.
- Exclusion of infants with obstructive sleep apnea or heart disease.
- Recording and analysis of anthropometric data, indications, dosages, sedation outcomes, and clinical events.
Main Results:
- 277 infants (median age 51.5 weeks) received chloral hydrate (50-80mg/kg orally).
- Recurrent wheezing was the primary indication (56%).
- Minor complications (cough, respiratory distress, vomiting) occurred in 6.5%; one case of transient bradycardia resolved with stimulation. No resuscitation was needed.
Conclusions:
- Chloral hydrate is a safe and effective sedative for short infant procedures like PFTs at the studied doses.
- Strict adherence to dosing guidelines and contraindications is crucial.
- Continuous monitoring by trained staff is essential to manage potential adverse events.
Objective:
To describe the efficacy and safety of chloral hydrate sedation in infants for pulmonary function tests.
Methods:
All sedation attempts for pulmonary function tests in infants carried out between June 2007 and August 2014 were evaluated. Obstructive sleep apnea and heart disease were contraindications to the exams. Anthropometric data, exam indication, used dose, outcomes of sedation and clinical events were recorded and described.
Results:
The sedation attempts in 277 infants (165 boys) with a median age of 51.5 weeks of life (14 to 182 weeks) were evaluated. The main indication for the tests was recurrent wheezing (56%) and the chloral hydrate dose ranged from 50 to 80mg/kg (orally). Eighteen (6.5%) infants had some type of clinical complication, with the most frequent being cough and/or airway secretion (1.8%); respiratory distress (1.4%) and vomiting (1.1%). A preterm infant had bradycardia for approximately 15 minutes, which was responsive to tactile stimulation. All observed adverse effects were transient and there was no need for resuscitation or use of injectable medications.
Conclusions:
The data demonstrated that chloral hydrate at the employed doses is a safe and effective medicament for sedation during short procedures in infants, such as pulmonary function tests. Because of the possibility of severe adverse events, recommendations on doses and contraindications should be strictly followed and infants should be monitored by trained staff.

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...

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...
