简要总结
In intensive care, sleep disturbances are extremely common and represent a major source of discomfort for patients. Restorative sleep is very limited. Beyond being the primary source of discomfort reported by patients, these sleep disturbances are associated with difficulties in weaning from mechanical ventilation, an increased risk of delirium, and potentially higher mortality. Traditional treatments artificially increase the total duration of sleep but lead to disrupted sleep architecture.
Gamma-hydroxybutyrate (GHB) is currently used for several sleep disorders, such as narcolepsy, due to its ability to increase restorative sleep. This medication has been used for years as a sedative in intensive care. Despite these potential benefits, the efficacy of GHB has never been evaluated for sleep disturbances in intensive care settings.
This study focuses on evaluating the effectiveness of intravenous Gamma-hydroxybutyrate (GHB) in the treatment of sleep disorders in intensive care.
详细描述
In intensive care, sleep disturbances are extremely common and represent a major source of discomfort for patients. While the total duration of sleep is minimally affected, deep slow-wave sleep (N3) is significantly underrepresented. Beyond being the primary source of discomfort reported by patients, these sleep disturbances are associated with difficulties in weaning from mechanical ventilation, an increased risk of delirium, and potentially higher mortality. Traditional treatments with benzodiazepines or propofol artificially increase the total duration of sleep but lead to disrupted sleep architecture.
Gamma-hydroxybutyrate (GHB) is currently used for several sleep disorders, such as narcolepsy, due to its ability to reduce sleep onset latency, increase deep slow-wave sleep (N3), improve sleep quality, and enhance daytime alertness scores. Despite these potential benefits, the efficacy of GHB has never been evaluated for sleep disturbances in intensive care settings.
This study focuses on evaluating the effectiveness of intravenous Gamma-hydroxybutyrate (GHB) in the treatment of sleep disorders in intensive care. The primary objective of this pilot study is to show that the intravenous administration of GHB improves the duration (in minutes) of deep slow-wave sleep (N3 stage) in critically ill adult patients compared to a placebo

研究组 & 干预措施
GHB
Intravenous GHB (Gamma-OH) will be administered at a dose of 15 mg/kg as induction over 20 minutes (in a 100 mL NaCl bag), followed by a continuous infusion of 10 mg/kg/h over 8 hours (via an electric syringe pump) from 10:00 PM to 6:00 AM for one night.
干预措施: GHB (Drug)
Control
A placebo in the form of 0.9% NaCl (as Gamma-OH is transparent and completely soluble), administered intravenously as a induction (after a dilution in a 100 mL NaCl bag) and then continuously (without dilution via an electric syringe pump) for 8 hours from 10:00 PM to 6:00 AM for one night.
干预措施: Placebo (Drug)
