A convulsion, also known as a grand mal seizure, consists of rapidly contracting and relaxing muscles. Uncontrollable shaking occurs, sometimes to the point of unconsciousness. It is the most violent type of seizure, affecting the entire body.
Convulsions, like all forms of seizures, are brought on by chaotic electrical activity in the brain that transpires unexpectedly. A convulsion will sometimes begin at a localized area, but it soon spreads throughout the body. Prevention of injury is the central goal when treating a convulsion attack.
First Aid Instructions
Step 1
Dial "911," if this is the first time the person has had convulsions. Have someone else make the call while you perform the following emergency steps for treating convulsions. Help the person to lie down (if she is not already) to prevent a fall from occurring.
Step 2
Move any dangerous objects, like furniture and utensils, out of the area where the convulsions are taking place. Cushion the person's head with a pillow (or other soft object) to reduce the intensity of thrashing activity against the floor.
Step 3
Loosen any tight clothing to prevent suffocation. Roll the convulsing victim onto his side. This is to prevent any vomit from getting breathed into the lungs. Check the person's wrist for a medical identification bracelet. It may have specific instructions for treating the convulsions.
Step 4
Remain with the person during the duration of the convulsion attack, making sure she has a pulse and is breathing. If the convulsions last more than 2 to 5 minutes or the victim displays abnormal behavior after the attack, call 911.
Tips and Warnings
- If the person is at a known risk of convulsions, watch for warnings signs of an upcoming attack. These may include anxiety, dizziness, nausea and vision problems.
- Do not put anything between the person's teeth during the convulsion attack. Do not try to restrain the person.
