Loss of Consciousness

What are the treatments for the condition?

Often, treatment is not needed for a simple loss of consciousness because the person usually returns to normal within a few minutes. A person who faints should be positioned on his or her back. The nearest witness who feels comfortable doing so should check the person's airway and breathing.

If the person remains unconscious, first aid for unconsciousness should be given:

At the hospital, the medical team will try to maintain basic vital functions, such as breathing and blood pressure. The person may need a ventilator, or artificial breathing machine, or medications to maintain blood circulation. Oxygen, intravenous (IV) fluids, and close monitoring of the person are done routinely.

Further treatment is directed at the cause of the loss of consciousness. For example, glucose, a form of sugar, may be given to a person who has low blood sugar. If a heroin overdose is the reason for unconsciousness, Naloxone can be given to reverse it. Someone with a subdural hematoma may need brain surgery. An individual with an infection may need antibiotics.

What are the side effects of the treatments?

Side effects depend on the treatments used. For example, antibiotics may cause allergic reactions or stomach upset. Surgery carries a risk of bleeding, infection, and allergic reaction to the anesthesia.

What happens after treatment for the condition?

After fainting, the individual usually needs no further treatment or monitoring. Further treatment may or may not be needed for other conditions. For example, a person with serious kidney disease, liver disease, or diabetes usually needs lifelong monitoring and treatment.

How is the condition monitored?

A person who faints may receive a few tests to make sure there is not a serious cause. He or she may be observed for a brief period and then sent home. Other monitoring can be used to diagnose the cause of the condition. Any new or worsening symptoms should be reported to the healthcare provider.
