F irst Aid

Even though we are careful, accidents sometimes do happen. A person may break a bone

or get a cut or burn himself. There are things you can do to help the person even before
a doctor can see him or her. This is called first aid. If necessary, you should also call a
doctor or take the person to a doctor.

Let us learn some ways to deal with certain accidents or emergencies.

First Aid in Case of Fracture

A fracture means that a bone in the body
has broken or cracked. The injured part
becomes swollen and painful, and needs to
be supported. Be very gentle, while helping

a person with a fracture. If possible, do
not move the fractured part, because it
could cause more injury. Always give it
good support before moving it. This is very

important.

If there is a fracture in the leg, support a
broken bone by tying a splint or two long
sticks along the fracture. The supports

should be long enough to keep the broken
bone in its normal position, and keep the
weight off the broken part.
