Study Notes
Barbiturates
- Classified under the Controlled Substances Act: Schedule II for short-acting, Schedule III for intermediate-acting, and Schedule IV for long-acting hypnotics
- Long-acting group includes Phenobarbital and Mephobarbital, used to control seizures in epilepsy
- Intermediate-acting barbiturates, such as Butabarbital, are useful as sleep sustainers for maintaining long periods of sleep
Side Effects and Adverse Reactions
- Hangover: residual drowsiness, impaired reaction time due to lingering active metabolites in the body
- REM Rebound: vivid dreams and nightmares, occurs after taking a hypnotic, especially after prolonged use and abrupt stopping
Pharmacokinetics
- Liver bio transforms hypnotics into active metabolites that persist in the body, causing drowsiness
Nursing Process: Patient-Centered Care
- Assess baseline vital signs and laboratory tests for future comparisons
- Obtain a drug history, especially CNS depressants with nonbenzodiazepine hypnotics that can depress respirations
- Ascertain the patient’s problem with sleep disturbance
Melatonin Agonists
- Act by selectively targeting melatonin receptors to regulate circadian rhythms in the treatment of insomnia
- Ramelteon: has a half-life of 1 to 2.6 hours, with adverse effects including drowsiness, dizziness, fatigue, headache, nausea, and suicidal ideation
Anesthetics
- Classified as general and local, depress the CNS, alleviate pain, and cause a loss of consciousness
- First anesthetic, nitrous oxide (“laughing gas”), was used for surgery in the early 1800s
Children and Older Adults Sleep Cycle
- Children: few REM sleep periods, longer periods of stage 3 and 4 NREM sleep
- Older adults: decrease in stage 3 and 4 NREM sleep, frequent waking periods
Sedative-Hypnotics
- Treatment of sleep disorders
- High doses can suppress the respiratory center in the medulla, causing respiratory depression
- Hypersensitivity: skin rashes and urticaria can result from taking barbiturates
