If the foreign body is embedded in the eyeball, send the casualty
to hospital for treatment immediately.

Foreign Bodies In The Nose
Children often stuff foreign bodies such as buttons or marbles into
their noses. These objects will injure their respiratory membrane
and prevent normal breathing. They may even slip down to the trachea.
|
| |
Treatment
:
|
| |
|
(A) |
Do not attempt to take the foreign object out.
|
| |
|

Notice for any difficulty in breathing.
|
| |
|
(D)
|
Send the casualty to hospital immediately.
|
| |
(3) |
Foreign
Bodies In The Ears
Children often stuff foreign bodies such as beads or peas into their
ears. Sometimes, insects will crawl into the ears to cause discomfort,
which will result in temporary loss of the sense of hearing. If the
body is inserted too deep, the eardrum will be injured.
|
| |
Treatment
:
|
| |
|
(A)
|
Do
not try to remove object to avoid damaging the ear canal or eardrum.
|

baby oil) to float the object out.
|

|
(C) |
Send the casualty to hospital for treatment.

Swallowing
Foreign Bodies
Swallowing small round bodies will not cause any damage. However,
swallowing a sharp item like a safety pin, sewing needle or a sharp
bone will injure the throat and the digestive tracts. In addition,
swelling of the throat or choking due to injury will obstruct the
airway.
|
| |
Treatment
:
|

|
(A)
|
Reassure
the casualty.

Give nothing by mouth.

removed by hand. Thin, hard card such as identity card should be used
to scratch out the sting by following the direction of the point of
the sting so as to get the poison out.

Frostbite
In freezing weather, the exposed parts of the body such as the nose
tip, ear lobes, cheeks and chin - may develop frostbites as the skin
on them cools and the blood vessels become constricted thus cutting
off the blood supply to the area. The hands and feet can also be affected
even when they are enclosed in gloves and boots. In severe cases,
gangrene may develop unless the affected part is warmed.
| - |
The
affected part of the body is cold, painful and stiff at first.
|
| - |
The
skin hardens and turns blue or white. Usually, it also goes
numb, so that the feeling of cold and pain disappears.
|
| - |
Partly
thawed frostbite is blue in colour and there may be blood-filled
blisters in the affected area.
|
|
| |
Treatment
:
|
| |
|
(1)
|
Remove the casualty by stretcher to a warm place as soon as possible.
|
| |
|
(2) |
Immediately remove anything of a constrictive nature - gloves, rings
and boots.
|
| |
|
(3) |
Warm up the frost bitten parts by sharing of body heat.
|
| |
|
(4)
|
Warm up the casualty's affected part in warm water at a temperature
acceptable to the elbow.
|
| |
|
(5)
|
The sense of pain will return and the skin will turn red as the part
thaws out. Dry and lightly bandage the thawed area with gauze and
wool.
