1)Hemostasis :The first thing to do when a skin laceration occurs is hemostasis. It is best to hemostasis by direct compression method using a clean towel or gauze.

2) Wound cleaning : After the hemostasis, you should wash the wound with running tap water to minimize any soil or other contaminants on the wound.

3) Debridement : When you go to a hospital, tissue destruction is so severe that you can digest a piece of skin or a piece of skin that is not likely to survive after suturing, which is called marginal resection.

4) Repair : Skin laceration should eventually be performed. The earlier the repair, the better the outcome of the treatment should not be delayed.

1)Foreign object sticking out
- Any foreign body in any part of the body should never be removed from the field.
- If a foreign object is obstructing the airway, it must be removed from the field, and if the bleeding continues considerably, the palm of the hand should be pressed around the foreign object.

2)Foreign object in the eye
- If the granule type is involved, never rub your eyes. Repeat the blinding in the water by putting the water in the wash basin, soaking it in the water.
- Ingredients When untreated liquids spill into your eyes, immediately wash them with running water for at least 15 minutes. Do not forget that washing your eyes with running water is the most important thing.

3)Foreign objects in the ear
- When the worm enters the ear, it continues to dig into the eardrum, causing severe pain and loud noise, which makes the patient nervous and anxious. It is good to come to the hospital immediately. When you come to the hospital, anesthetic medicine is poured into the ear canal to kill the insect and remove it safely.

4) Foreign matter caught in the neck
- Fish thorns: Swallow a spoonful of rice. If you have a wound in your neck, you should immediately go to the hospital and remove it.
- Large chunk of foreign object: As there is a risk of airway obstruction, call 119 immediately and move to the hospital.

5) Swallowed substance
- When the swallowed substance reaches the stomach without getting caught in the esophagus, most of the foreign matter is discharged into the stool without causing any major problems. Therefore, do not attempt to remove any toxins that are not toxic specifically, but wait until they come out in the stool.
- Foreign matter that releases toxic substances should be removed as soon as possible. Mercury batteries, such as stomach acid or digestive juices can be corroded and internal material can leak out, so when you are in the stomach, you should remove it with an endoscope.

1) The number of wound sites must be reduced through wound cleaning or disinfection.

2) Use sterilized gauze or a clean towel to directly compress and bleed the bleeding site.

3) Go to the hospital quickly and get the treatment you need.

1) Check the patient's consciousness, breathing, and circulation.

2) Transfer to the hospital promptly.

3) Move the patient to a cool place, remove the clothes, and lay them straight on.

4) Keep the patient's body temperature down quickly.

5) When the patient's consciousness recovers, no further lowering of body temperature is performed.

6) If the temperature drops to about 39 ° C, hypothermia and systemic convulsions can occur, and the body temperature is no longer lowered.

7) Head and shoulders are slightly raised.

8) If the patient has systemic seizures, take appropriate measures.

1) Collect the types of poisons, intake, and when they took them.

2) If the patient is unconscious, check for airway, respiration, and pulse and treat as needed.

3) For conscious patients, place the patient in a recovery position. The restored posture, when the patient is lying down on his left side and is in this position, not only slows down the time for the contents to be transferred to the small intestine, but also prevents the airway obstruction when the patient is vomiting.

1) Move the patient to a safe place, prevent further burns (remove burned clothing), remove watches, rings, etc. before the skin is swollen.

2) When dressed in hot water, cool it for 15 to 30 minutes with cold water before peeling, then peel it off.

3) Cover the burn area with vaseline or burn gauze and wind the bandage gently.

4) If blisters are present, do not blow them.

5) Place the burn area higher than the heart and reduce swelling.

6) When a significant portion of the body has been burned, it is safe to go to the hospital after first aid at home, even if the baby is burned with light, wet the cold with a clean large towel and wrap it around the entire body.

1) Call 119.

2) If the accident occurred after the dive, there is a possibility of damage to the neck bone. Fix the cervical spine and perform artificial respiration or heart massage as necessary.
   Wet garments may cause hypothermia as they continue to be treated, so remove and cover the blanket.

3) If a patient is thought to have no cervical damage, vomit can be prevented from entering the lungs and the face is turned to one side to secure airway.

4) Continue CPR if necessary during transfer to hospital.

5) If the patient has respiration and pulse, take a rescue posture.

6) Any person who falls into the water should be transported to the hospital for examination.

- When outdoors, wear long clothing.

- It may be helpful to use tick repellents together.

- After returning home, be sure to wash off the outer garment and wash it.

- After outdoor activities, I keep my shower and bath clean and always clean.
