Keep in mind these first aid common sense in life

  Life is a kaleidoscope, but many accidents also happen. The following first-aid common sense in daily life may be helpful and prepared for you.
  Injured by bee stings: You should carefully pull out the remaining stinger at the first time, gently squeeze the wound, squeeze out the venom, and apply ammonia or soda water in time. If it is stung by the more toxic bumblebee, it should be washed immediately with weak acidic liquid such as vinegar to neutralize the venom. In severe cases, a tourniquet can be tied to the proximal end of the wound and relaxed every 15 minutes. The strapping time should not exceed 2 hours, and local cold compress can reduce swelling and pain. If abnormal reactions such as nausea and dizziness occur, go to the hospital immediately.
  Flying insects drilled into the ears: Never use your fingers or ear spoons to dig it out, as the worms will drill deeper and damage the periosteum. It is recommended to use a flashlight to illuminate the ear canal in a dark place, and use the phototaxis of insects to draw out flying insects with light.
  Heatstroke: During heatstroke, the patient should be quickly transferred to a cool, ventilated place for rest, loosen or undressed, and a cold towel can be placed on the head. You can use alcohol, ice water or cold water to wipe the whole body, and then use a fan or electric fan to blow the air to accelerate heat dissipation. If conditions permit, move the patient to a place with air-conditioning. At the same time, give a small amount of cold saline to moderate heat stroke. When the patient suffers from confusion, convulsions, or has lost consciousness during heat stroke, he should be sent to the hospital immediately.
  Sunburn: If the skin is red, swollen, and painful in the sun, apply a cold towel or ice to the affected area in time, and apply vitamin E moisturizer. If you have blisters on your skin, don’t break them. Ask your doctor to avoid secondary infections. People who are prone to sunburn can eat vitamin C and vitamin E to enhance the body’s immunity to sunlight and reduce the degree of skin damage.
  Scald: Immediately rinse or compress the scalded area with cold water for 15 minutes to relieve pain and reduce the degree of scald. It is not advisable to apply medicine on the wound without permission, and even less soy sauce and vegetable oil. If there are blisters on the burned area, don’t pick them up. Cover them with clean gauze and go to the hospital for treatment.
  Trauma bleeding: small or superficial wounds should be washed with cold boiling water or clean tap water first, but do not remove clotted blood clots. If there are foreign objects such as glass fragments and knives inserted into the wound, do not touch, press or pull out. You can squeeze the wound edges on both sides, wrap them with sterile gauze and bandages, and go to the hospital for treatment immediately. The injuries caused by collision and beating have bleeding or swelling and pain under the skin. The wound can be covered with sterile gauze or a clean towel, coldly compressed with an ice pack for half an hour, and then compressed and bandaged to reduce pain and swelling.
  Knife cut: If the wound is not large and clean, and there is not much bleeding, the injured finger can still perform extension and flexion activities. The wound and its surrounding skin can be disinfected with medical iodine. After drying, cover the wound with sterile gauze or band-aid. If the wound is large and deep, hemostasis should be compressed and immediately go to the hospital for treatment. If the finger is cut off, the injured finger should be lifted immediately, and then the wound should be directly wrapped with clean gauze to stop the bleeding. If the blood still flows out, you can also wrap the tourniquet (or replace it with a general cleaning rope) at the root of the finger to stop the bleeding, wrap the broken finger with a sterile cloth, and put it in a clean plastic bag. Unless the pollution of severed fingers is particularly serious, it is generally not recommended to rinse yourself, and do not soak the broken fingers with any liquid, and go to the hospital for treatment as soon as possible.
  Calf cramps when swimming: First, stay calm, take a deep breath, dive your head into the water, then float your back on the water like a jellyfish, grab your toes with both hands, and pull hard in your direction. If it doesn’t work once, it can be repeated many times, and the muscle will slowly relax and return to its original state. Practice this method more often when swimming to escape from accidents. Warm up before swimming to prevent sudden calf cramps during swimming.
  Fracture: The injured limb (finger) should be fixed before being sent to the hospital. Branches, bamboo poles, wooden boards, wooden sticks, magazines, etc. can be used as temporary splints for fixation according to local conditions. If there is a lack of materials, the upper limb can be fixed on the trunk, and the lower limb can be fixed on the opposite healthy limb.
  Sudden hypoglycemia: Mainly manifested as hypoglycemia syndrome, which may include symptoms of palpitation, palpitations, hunger, weakness, trembling of hands and feet, pale skin, sweating, increased heart rate, and mildly increased blood pressure. If it is only mild hypoglycemia, the patient is conscious and can eat a few candies, biscuits or half a cup of sugar water in time to achieve the effect of quickly correcting hypoglycemia, and the symptoms of hypoglycemia will usually disappear after ten minutes.
  Seizures: Before the ambulance arrives, the patient’s head can be turned sideways to prevent vomiting causing suffocation. Afterwards, find something that is clean and not easy to break into the patient’s upper and lower teeth to prevent tongue bites.
  Gas poisoning: When a gas leak is found, immediately turn off the gas and open the window for ventilation. If you are going to be rescued, take a full breath before entering the gas-filled room, then cover your mouth and nose with a wet towel or handkerchief to prevent poisoning. After moving the poisoned person to a ventilated place, loosen his clothes and observe his consciousness, heartbeat and breathing. If there is no heartbeat and breathing, give artificial respiration and chest compressions immediately; if you have heartbeats and breathing, you should call the emergency number immediately and carry out hyperbaric oxygen treatment in time to avoid leaving sequelae. Do not turn on the lights, ring the bell, make phone calls, or use lighters, matches, etc. before the gas is exhausted to avoid an explosion.
