What does sedation do to the brain?

Sedatives work by modifying certain nerve communications in your central nervous system (CNS) to your brain. In this case, they relax your body by slowing down brain activity. Specifically, sedatives make the neurotransmitter called gamma-aminobutyric acid ( GABA ) work overtime.

What is the most common complication of sedation?

When compared with local anesthesia alone, the two most significant negative variables introduced by moderate sedation, as well as deep sedation and general anesthesia, are the added risks for either respiratory depression, ie, hypoventilation, or airway obstruction in the deeply sedated or unconscious patient.


Does sedation make you act weird?

Sedation Alters Your Brain Chemistry To Cause Changes In Behavior & Consciousness. As you may already know, the helpful effects of dental sedation boil down to the same basic process, no matter what type of sedative is used.

Is being sedated the same as being put to sleep?

Both sedation and general anesthesia are used for different types of medical and surgical procedures. The difference between sedation and general anesthesia is degrees of consciousness. Sedation is a sleep-like state where patients are generally unaware of surroundings but may still respond to external stimuli.

What part of the brain do sedatives affect?

Sedative/hypnotics depress the limbic system of the brain, which regulates emotional and behavioral responses, and reticular formation which regulates sleep and consciousness.


Do sedatives affect memory?

Outcomes. The primary outcome will be loss of memory after sedative administration (anterograde amnesia). All types of memory (sensory, short-term, and long-term) will be considered. The secondary outcome will be loss of memory before sedative administration (retrograde amnesia).

Why would someone with a mental health problem take sedatives?

Because of their ability to relieve physical stress and anxiety and promote relaxation, doctors may also prescribe sedatives to people with insomnia, anxiety disorders, and muscle spasms. People with bipolar disorder, post-traumatic stress disorder, and seizures may also benefit from prescription sedatives.

What to expect after being sedated?

After conscious sedation, you will feel sleepy and may have a headache or feel sick to your stomach.

Your blood pressure will be checked with an arm cuff about every 15 minutes.


What happens when a patient is over sedated?

Dangers of Oversedation

Oversedation may result in the interference of adequate oxygenation and ventilation, resulting in a decrease of oxygen (hypoxia), or no oxygen (anoxia), and/or an excess amount of CO2 (hypercarbia) in the blood.

Is sedation safer than general anesthesia?

IV sedation does cause partial memory loss, and patients will not remember any of their procedure. Recovery is fast and patients will be back to their routine quickly. IV sedation is a safer option compared to general anesthesia.

What is the most serious complication of conscious sedation?

Of these, hypoxemia is the most critical complication; it is caused by airway obstruction secondary to hypoventilation and apnea due to central nervous system depression. The incidence of hypoxemia among patients under sedation is reportedly 6–18% [4–6].

Why won t someone wake up from sedation?

Causes of Delayed Emergence. In most cases, a delayed awakening from anesthesia can be attributed to the residual action of one or more anesthetic agents and adjuvants used in the peri-operative period. The list of potentially implicated drugs includes benzodiazepines (BDZs), propofol, opioids, NMBAs, and adjuvants.
