What is head injury observation? — A head injury happens when a person hits their head on a hard surface or is hit in the head with an object. Head injuries can be mild or more serious. Sometimes, they can affect the brain.
"Observation" means watching a person for problems after a head injury. Some effects of a head injury might not be seen right away. This is why observation is important.
The following is information about observing an adult (18 years or older) after a head injury.
Why does a person with a head injury need to be observed? — Some effects of a head injury can show up in the first few hours. Others might not show up for days to weeks after the injury. It is important to help watch for these signs in the person who had the head injury.
Symptoms that can happen minutes to hours after a head injury include:
●Memory loss – People sometimes forget what caused their injury, as well as what happened right before and after the injury.
●Confusion
●Headache
●Dizziness or trouble with balance
●Nausea or vomiting
●Feeling very tired or sleepy
●Acting cranky, irritable, or not like themselves
Other symptoms that can happen hours to days after a head injury include:
●Trouble walking or talking
●Memory problems or problems paying attention
●Trouble sleeping
●Mood or behavior changes
●Being bothered by noise or light
●Changes in eyesight
What should I watch for at home? — Ask the doctor what you need to do when you are with the person who was injured. Make sure that you ask questions if you do not understand what the doctor says. This way, you know what you need to do.
●Watch the injured person for the first 12 to 24 hours after they are home. Call the doctor if they have any problems. Make sure that the injured person is breathing normally, not vomiting, and not moaning while they sleep.
●When the person wakes up from sleep, make sure that they are acting normally and recognize you. If you see changes in how they look or act, call for help or go to the emergency department.
What else should I know? — After a head injury, the person might need to rest for a while and avoid any activity that makes their symptoms worse. To help their recovery:
●Offer a light diet and plenty of fluids to help with upset stomach.
●Encourage them to rest their body for the first day or 2. They do not have to stay in bed. Light activity is OK as long as it doesn't make their symptoms worse. This includes things like taking a shower or a walk. They should avoid heavier activities like sports or running.
●Remind them to rest their brain. This involves avoiding things that make symptoms worse. Examples include reading, watching TV, playing video games, or using a smartphone, tablet, or computer.
●The person's doctor might recommend taking a day or 2 off from work or school. Some people can have symptoms like trouble thinking, remembering, or paying attention that can last for weeks to months.
●Offer them an over-the-counter pain reliever for headaches. These include acetaminophen (sample brand name: Tylenol) and NSAIDs such as ibuprofen (sample brand names: Advil, Motrin).
●Remind them not to drink alcohol or use marijuana while they are recovering.
●Help them avoid another head injury. They should avoid sports, bicycle riding, or other activities where they can hit their head. Check with the doctor about when it is safe to return to these activities.
When should I call for help? — Call for an ambulance (in the US and Canada, call 9-1-1) if the person:
●Cannot be fully woken up
●Is acting confused or disoriented
●Has a sudden and persistent change in their behavior
●Cannot walk normally
●Has trouble speaking or slurred speech
●Has severe weakness or cannot move an arm, leg, or 1 side of their face
●Has a seizure, or jerking of their arms or legs they cannot control
Call the doctor or nurse for advice right away if the person:
●Has trouble concentrating, thinking clearly, or remembering things
●Has trouble waking from sleep or staying awake
●Has nausea or vomiting that is not improving
●Has blurry eyesight, double vision, or other problems seeing
●Has blood or clear liquid draining from their ears or nose
●Feels dizzy or faints
●Seems weak or has numbness in an arm, leg, or other body part
●Has a stiff neck
●Has a headache that is severe, gets worse, feels different, or does not get better with over-the-counter medicines
If any of the above symptoms seem severe, or if you are concerned about the person but cannot reach the doctor or nurse, seek emergency help. These things don't always mean that there is a serious problem, but seeing a doctor or nurse is the only way to know for sure.
