Sedation Practices

Sedation practices are clinical methods used to reduce anxiety, discomfort, awareness, or movement while preserving patient safety during medical procedures and care. They range from minimal sedation to deep sedation, with clinicians selecting and titrating medications according to the procedure, patient factors, and desired level of responsiveness; commonly used agents act through pathways such as GABA-A or alpha-2 adrenergic receptors. Continuous assessment of consciousness, breathing, oxygenation, circulation, and airway function helps detect complications and guide intervention. Appropriate sedation practices support diagnostic procedures, surgery, emergency care, and intensive care while balancing comfort, cooperation, recovery time, and risks such as respiratory depression.

Sedatives and Hypnotics: Overview

0 Views •

2024

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...

Sedatives and Hypnotics Drugs: Barbiturates

2024

Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A key...

Sedatives and Hypnotics Drugs: Benzodiazepines

2024

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...

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...
