General anesthesia is, in fact, a reversible drug-induced coma. Nevertheless, anesthesiologists refer to it as “sleep” to avoid disquieting patients.
Does sedated mean coma?
While a medically induced coma puts a patient in a very deep unconscious state, sedation puts a patient in a semi-conscious state. Sedation is often given to allow a patient to be comfortable during a surgical or medical procedure and is administered through an intravenous catheter (IV), with minimal side effects.
Can sedation cause brain death?
The risk of dying in the operating theatre under anaesthetic is extremely small. For a healthy person having planned surgery, around 1 person may die for every 100,000 general anaesthetics given. Brain damage as a result of having an anaesthetic is so rare that the risk has not been put into numbers.
What causes a coma after surgery?
It is often caused by the effect of drugs administered during the surgery. It can also be caused by other etiologies such as metabolic and electrolyte disturbances. However, prolonged coma after GA has not been reported in the literature.
Can sedation affect your brain?
Exposure to anesthesia to the aged brain can be a risk of the long-lasting impairments of cognitive function. However, the neuroprotective property of general anesthetics in brain injury is also increasingly recognized.
How do coma patients poop?
It takes a conscious effort to keep the muscles of the anus completely closed to prevent pooping, so typically in comatose patients, the muscles are relaxed, and the poop just periodically comes out, so the care staff comes in to clean up the patient and change the bed linens regularly.
What is the chance of surviving a coma?
Within six hours of coma onset those patients who show eye opening have almost a one in five chance of achieving a good recovery whereas those who do not have a one in 10 chance. Those who show no motor response have a 3% chance of making a good recovery whereas those who show flexion have a better than 15% chance.
Can a brain dead person be revived?
Brain death (also known as brain stem death) is when a person on an artificial life support machine no longer has any brain functions. … A person who’s brain dead is legally confirmed as dead. They have no chance of recovery because their body is unable to survive without artificial life support.
What are the symptoms of brain death?

How do you confirm brain death?
New York State regulation defines brain death as the irreversible loss of all function of the brain, including the brain stem. See 10 N.Y.C.R.R. § 400.16. The three essential findings in brain death are coma, absence of brain stem reflexes, and apnea.
What are the stages of a coma?
Recovery may be grouped into the following four stages:
- Stage 1: Unresponsiveness. During this stage the patient does not respond consistently or appropriately. …
- Stage 2: Early responses. …
- Stage 3: Agitated and confused. …
- Stage 4: Higher level responses.
What part of the brain is damaged in a coma?
Comas are caused by damage to the brain, specifically the diffused bilateral cerebral hemisphere cortexor the reticular activating system. This area of the brain controls arousal and awareness.
What does being in a coma feel like?
Usually, comas are more like twilight states – hazy, dreamlike things where you don’t have fully formed thoughts or experiences, but you still feel pain and form memories that your brain invents to try to make sense of what’s happening to you.

- loss of memory of what happened during the procedure (amnesia)
- slow reflexes.
- low blood pressure.
- feeling sick.
