The Effect of Sodium Oxybate on Sleep Architecture

GHB

Brief Summary

The purpose of this study is to determine what effect sodium oxybate has on the functions of sleep in mechanically ventilated, critically ill patients hospitalized in an intensive care unit.

Intervention / Treatment

  • Sodium Oxybate (DRUG)
    The dose of sodium oxybate will be 4.5g every 4 hours x 2 doses. The first dose of study medication will be given at 10pm followed by the next dose four hours later and crossed over the next day
  • Placebo (DRUG)
    The dose of placebo sodium oxybate will be 4.5g every 4 hours x 2 doses. The first dose of study medication will be given at 10pm followed by the next dose four hours later and then crossed over the next day

    Sleep is disrupted in the critically ill and may lead to impaired neurocognitive function, decreased immune function, increased protein catabolism, and may compromise the ability to wean patients from mechanical ventilation. Critically ill patients may appear to sleep throughout most of their stay, but their quality of sleep is different from that of a normal healthy subject.Critically ill patients spend more time in the wakefulness stages of sleep (Stage 1 and 2) at the expense of the restorative stages (Stage 3 and 4) and REM sleep. These patients also experience an increased number of arousals and awakenings. Various factors are thought to be the cause of abnormal sleep architecture: ICU environment, pain, illness severity, psychosocial stress, medications, and mechanical ventilation.

    Sodium oxybate (Xyrem®) is the sodium salt of the central nervous system depressant γ-hydroxybutyric acid (GHB) and is currently approved for use in narcoleptic patients to improve cataplexy and excessive daytime sleepiness.

    Studies evaluating the use of sodium oxybate in narcoleptic patients suggest that sodium oxybate is effective at increasing slow-wave sleep, sleep efficiency, sleep latency, and REM-sleep efficiency, while also decreasing REM-sleep latency, stage 1 NREM sleep and sleep fragmentation.3, 16-19 Currently there is a lack of data evaluating the effects of sodium oxybate on sleep in critically ill patients. Obtaining evidence that sodium oxybate improves sleep architecture in the critically ill, may provide the foundation to complete future studies evaluating the effect of sodium oxybate on clinical outcomes such as duration of mechanical ventilation and length of ICU stay. Based on sodium oxybate's ability to improve sleep architecture in narcoleptic patients along with the fact that critically ill patients have similar disrupted sleep architecture, it's postulated that sodium oxybate may improve the sleep architecture in critically ill patients.
