How do doctors induce a coma?

immediately after Felipe Massa's Formula One accident in Hungary on July 25th, it be reported the doctors had to induce a coma in Felipe. How did they do it, and why do they do in similar cases of herald injuries?

Thumbs up to Lion. She left out the ancient barbituates, which are still used, and the basic thinking is to decrease the metabolic requirements of the brain. Less metabolism means slighter needs for perfusion in people who are have problems regulating cerebral perfusion pressure.
We do it with a variety of drugs that are run surrounded by a continuous infusion. Propofol, Versed, Ativan, and Fentanyl are commonly used in ICU settings, with some Precedex being used more lately. Generally, someone wants to be on a ventillator (breathing machine) and have a variety of other tubes and such.

Usually this is done to keep the frightening experience of anyone in an ICU to a minimum. Many patients who need to be put on breathing machines or undergo extensive repeat surgeries would prefer not to be aware of it. Sometimes when they are too awake, they actively confrontation the "life support" machines and can worsen their condition.

If a patient has a principal injury, depending on the type, medical sedation to the point of unresponsiveness (coma) might be used in an attempt to control or prevent seizures. Head injuries predispose people to seizure, and uncontrolled seizures can be life and brain threatening. Source(s): Resident doctor-- emergency medicine
Lion named most of the drugs that are used, but the reasons for using these drugs in a herald injured patient aren't quite right. While it is true that many of these medication prevent seizures, they are not the first line agents used in this posture. In fact, we typically start patients on other antiepileptics (seizure medicines), usually Keppra or phenytoin, in addition to the agents used to make happen sedation if there is a particular concern about seizure.

In addition to the other reasons previously mentioned, management of intracranial pressure - which, simply like it sounds is the pressure inside the head - is one of the major reason for medically sedating a patient with a head injury. If the intracranial pressure become too high, the cells in the brain do not bring adequate blood flow and can be injured or killed. Sedation prevents the patient from combat the ventilator, moving about, feeling stress, sensing pain, and so on - adjectives of which can lead to elevation in the intracranial pressure. While it is nice to keep the merciful more comfortable, if that was the only goal we'd avoid putting the breathing tubes surrounded by in the first place.

Most of the medications listed above are used for sedation, not a true coma, but the result of their use is normally referred to as a coma by people who don't understand the difference because it's simpler to explain it that way. The true induction of a coma is done through the use of barbiturates, which be mentioned above. These medications also have a profound effect on the cerebral metabolic requirement of oxygen, much more so than the other sedative listed. Brain activity is essentially shut down so that the injured brain has lower requirements for nutrients and oxygen and might better tolerate the injury. There are several risks and potential complications with the use of these medicines, so they are used only as a ultimate resort.

The bottom line is that medically-induced sedation and/or coma is used to protect the brain while the initial period of swelling and increased intracranial pressure passes within hopes of preserving as much normal brain as possible. For now and the foreseeable future, once brain cell are severely injured/killed there is no treatment to restore them. This is why so much is done to preserve the healthy brain tissue after an injury. Source(s): I'm a neurosurgery resident and manage team leader injuries every day.
I agree, Lion nailed it, but she forgot to mention that this is also done contained by extreme burn cases too. People with severe burns are usually put into a coma state for a while until they start the healing process. This is to ease the trauma of the severe dull pain and emotional distress that comes with burns.
yes
Yell "Lights out!" and whack you in the back of the pave the way with a surgical mallet.
I'm sorry i can't carry any more specific, but they inject certain chemicals into the bloodstream, and they cause the brain to induce a coma. when the chemicals go away, the brain wake up. From my understanding, its like putting a computer into sleep mode. instead of turning it off, you simply consent to it rest without harming anything running. Continuing on with the metaphor, the pretext someones wants to put a computer to sleep is so that the computer can rest while nothing serious is sustained. Like wise, doctors use this method to allow the brain to rest and probability are in the accident, the brain started to swell, which would have head to brain damage/trauma. By putting the person into a coma, the brain is allowed to (pardon this awful pun) rethink its actions, ie stop swelling. by that time doctors would have be able to do what they can to the wound. like i said though, im not a doctor.
