A drug-induced coma, better known as sedation in the medical field, is commonly used in medical, surgical and neurological intensive care units.
Is sedation the same as 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 coma?
1). General anesthesia is, in fact, a reversible drug-induced coma. Nevertheless, anesthesiologists refer to it as “sleep” to avoid disquieting patients. Unfortunately, anesthesiologists also use the word “sleep” in technical descriptions to refer to unconsciousness induced by anesthetic drugs.
Can patients hear when sedated?
Nursing and other medical staff usually talk to sedated people and tell them what is happening as they may be able to hear even if they can’t respond. Some people had only vague memories whilst under sedation. They’d heard voices but couldn’t remember the conversations or the people involved.
How long can you stay in an induced coma?
In most cases, a coma is induced for a few days up to two weeks; induced comas longer than a month are extremely rare. “It’s very much dependent on the individual circumstances,” Souter said. Like most medical procedures, an induced coma carries some risks.
How long does it take to come out of sedation in ICU?
All patients received continuous sedation and were sedated longer than 7 days. The median duration of sedation before discontinuation of sedation was 12 days (interquartile range 7–14 days).
Can sedation cause death?
Anesthesia is very safe
“In the 1960s and 1970s, it wasn’t uncommon to have a death related to anesthesia in every one in 10,000 or 20,000 patients,” he says. “Now it’s more like one in every 200,000 patients — it’s very rare.”
Can you go into a coma from too much anesthesia?
Failure to arouse and delayed awakening are the most common early neurologic problems following general anesthesia. True prolonged postoperative coma is relatively uncommon, with estimates ranging from 0.005 to 0.08 percent following general surgery, but with higher rates reported after cardiac surgery.
What is the chance of surviving a coma?
It can be seen that the likelihood of a good recovery in all patients is only 10%. It is less than 5% in those who have suffered subarachnoid haemorrhage or stroke, about 10% in those with hypoxic–ischaemic injury, but as high as 25% in those metabolic or infective causes of coma.
Can someone in a coma hear you?
Can Your Loved One Hear You. During a coma, the individual is unconscious, meaning they are unable to respond to any sounds. However, the brain may still be able to pick up on sounds from loved ones. In fact, some studies suggest talking and touching a loved one while they are in a coma may help them recover.

Can you breathe on your own in a medically induced coma?
Someone in a coma will also have very reduced basic reflexes such as coughing and swallowing. They may be able to breathe on their own, although some people require a machine to help them breathe. Over time, the person may start to gradually regain consciousness and become more aware.
What are the side effects of a medically induced coma?
Complications that can occur from medically induced coma include:
- Blood clots.
- Infection, particularly pneumonia and other lung infections.
- Heart problems.
- Pressure sores and weakness from immobility.
- Vivid nightmares and hallucinations.
Can you hear when in an induced coma?
They cannot speak and their eyes are closed. They look as if they are asleep. However, the brain of a coma patient may continue to work. It might “hear” the sounds in the environment, like the footsteps of someone approaching or the voice of a person speaking.
