Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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: Overview01:23

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
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...
CNS Depressants: Barbiturates and Benzodiazepines01:14

CNS Depressants: Barbiturates and Benzodiazepines

CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...
Management of Insomnia01:19

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
Sedatives and Hypnotics Drugs: Benzodiazepines01:19

Sedatives and Hypnotics Drugs: Benzodiazepines

Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Area of Science:

  • Medical-Surgical Nursing
  • Sleep Medicine
  • Patient Safety

Background:

  • Hospital routines disrupt patient sleep, increasing risks of delirium and falls.
  • Sedative use is common but carries significant risks.
  • Limited research exists on sleep promotion interventions in medical-surgical units and their effect on sedative use.

Purpose of the Study:

  • To identify causes of sleep disruption in medical-surgical patients.
  • To assess if reducing sleep disruptions lowers sedative use.
  • To evaluate the impact of the Somerville Protocol on patient sleep and sedative administration.

Main Methods:

  • An interventional trial with historical controls was conducted on a medical-surgical unit.
  • The Somerville Protocol established an 8-hour "Quiet Time" with automated lights-off, controlled noise, and minimized routine awakenings.
  • Nurses, physicians, and patients were blinded to as-needed sedative use measurements.

Main Results:

  • Hospital staff activities were the primary reported sleep disturbance, reduced by 38% with the intervention.
  • As-needed sedative use decreased by 49% overall (32% to 16%), with a 62% reduction in patients over 64.
  • Patient-reported sleep quality via the Verran Snyder-Halpern (VSH) scale remained unchanged.

Conclusions:

  • Minor adjustments to hospital routines, such as modifying vital sign and medication schedules, can significantly decrease sedative use.
  • The Somerville Protocol demonstrates a practical approach to improving sleep environments and reducing medication reliance in hospitalized patients.
  • Targeting routine disruptions is key to reducing sedative administration and associated risks in general hospital populations.
