Analysis of Risk Factors for Chloral Hydrate Sedative Failure with Initial Dose in Pediatric Patients: a Retrospective Analysis.

Abstract

BACKGROUND:

Although chloral hydrate has been used as a sedative for more than 100 years, dozens of studies have reported that it has inconsistent sedative effects and high sedation failure rates with initial dose. The high failure rates may lead to repeated administration of sedatives, guardians' dissatisfaction, parental anxiety, increasing medical workload as well as leading to an increase of adverse events. Our aim is to identify the risk factors associated with chloral hydrate sedative failure with initial dose in children undergoing noninvasive diagnostic procedures.

METHODS:

Pediatric patients who underwent chloral hydrate sedation for noninvasive diagnostic procedures at our institution between 1 December 2019 and 1 January 2021 were retrospectively analyzed. Data collected included patients' age, gender, weight, sedation history, sedation failure history, type of procedures, initial dose of choral hydrate, sleep deprivation, sedation failure with initial dose, and sedative duration. The initial dose was classified into three levels: reduced dose (< 40 mg/kg), standard dose (40-60 mg/kg), and high dose (> 60 mg/kg). The patients were divided into three cohorts according to the different initial doses.

RESULTS:

A total of 15,922 patients were included in the analysis; 1928 (12.1%) were not well-sedated after administering the initial dose of chloral hydrate. The highest sedative failure was observed in the reduced dose group. By multivariate regression, we identified that heavier weight, patients with a history of sedation or a history of sedation failure, and patients who received magnetic resonance imaging (MRI) or more than one procedure simultaneously were associated with an increased odds of sedation failure at the initial dose. However, outpatients, patients undergoing hearing screening, and patients with sleep deprivation were favored regarding chloral hydrate sedative success.

CONCLUSION:

An alternative drug or drug combination is necessary in patients with heavier weight, those with a sedation history or sedation failure history, and those undergoing an MRI or more than one procedure simultaneously, whereas chloral hydrate is an appropriate sedation option for outpatients, patients undergoing hearing screening, and those with sleep deprivation.
