What are the side effects of a short-term induced coma?
Dec 11, 2016 · A short-term induced coma can have little to no side effects and a short-term induced coma is usually anything less than 72 hours. Side effects of an induced coma may also vary depending on age as well as any existing pre-medical history.
Mar 16, 2022 · A medically induced coma may continue for 24–48 hours at a time until swelling or seizures subside. The short-term and long-term outlook for a person awakening from a medically induced coma depends on the underlying reason for the coma, the extent of brain damage, and other factors.
Jul 7, 2023 · Long-term side effects of medically induced coma may resolve with appropriate treatment and prevention strategies or may be lifelong. The most prevalent ones are as follows: Delirium.

A medically induced coma is usually a last resort option to prevent further brain damage after a serious heart attack or cardiac arrest.
A medically induced coma is a controlled, reversible slowdown of brain function to protect the brain after a severe injury or event, such as a heart attack leading to cardiac arrest. It’s used to allow the brain to heal after it has been deprived of healthy circulation.
A doctor may also use a medically induced coma if brain damage has occurred from a car accident, drug overdose, gunshot, or other serious injury.
Heart attack recovery usually does not require as serious a step as a medically induced coma. But in some cases, particularly if cardiac arrest follows a heart attack, it may be necessary.
A medically induced coma can help the brain and the rest of the body recover more easily. It can also improve the odds of a better outcome.
This article takes a closer look at medically induced comas, including when they’re used, their benefits, and outcomes.
To induce a temporary coma, a doctor administers anesthetic drugs and puts you in a controlled, closely monitored state of unconsciousness. Your brain and metabolism still function but at a reduced level.
While in an induced coma, you are on a ventilator to maintain healthy respiration. Your medical team monitors brain wave activity with an electroencephalogram (EEG).
Targeted temperature management is also a cornerstone of post-cardiac arrest care for people who remain unresponsive after heart function has been restored.
Studies have found that keeping a person in a mild state of hyperthermia — between 89.6°F (32°C) and 96.8°F (36°C) — for 24 hours reduces swelling and damage to the brain and improves neurological outcomes.
A heart attack can reduce blood flow to the brain, potentially causing brain damage.
If the heart attack is mild or treated quickly, there are fewer risks to brain health and a medically induced coma wouldn’t be necessary.
However, a brain that has been deprived of healthy circulation for an extended time or has experienced some other type of trauma is going to work extra hard to maintain function and recover from the damage. There may be swelling and sudden, severe inflammation in the brain.
A medically induced coma can take some of that extra burden off the brain while it recovers, allowing the swelling and inflammation to ease.
There is no optimal time to remain in a medically induced coma. Ideally, you would be in that state for as short an amount of time as necessary to protect the brain and resume the body’s normal functions.
Unlike serious head trauma or similar injury, doctors can often effectively treat a heart attack and restore blood flow in a matter of hours.
Like any major procedure, a medically induced coma has some potential risks and complications. Most side effects, such as disorientation and sleeping difficulties, are temporary.
Some of the more serious and long-term risks can include:
•delirium (memory problems and hallucinations)
•seizures
Because a medically induced coma after a heart attack is reversible, the outlook for a person being induced is usually better than it would be for someone who slipped into a coma from cardiac arrest outside of a hospital setting.
Generally, the shorter the time a person is in a therapeutic coma, the better the chances for a positive outcome.
A medically induced coma after a heart attack is an extreme measure, but it may be necessary if the brain is at risk of severe and permanent damage.
Some lingering cognitive challenges may be present after coming out of the coma, but working closely with your healthcare team may improve your recovery.

Induced coma usually results in significant systemic adverse effects. The patient is likely to completely lose respiratory drive and require mechanical ventilation ; gut motility is reduced; hypotension can complicate efforts to maintain cerebral perfusion pressure and often requires the use of vasopressor drugs.
Dec 14, 2022 · Overview. Coma is a state of prolonged loss of consciousness. It can have a variety of causes, including traumatic head injury, stroke, brain tumor, or drug or alcohol intoxication. A coma may even be caused by an underlying illness, such as diabetes or an infection. Coma is a medical emergency.
