2. Common first aid knowledge
(1) bleeding
The purpose is to reduce the blood flow rate and prevent massive blood loss, leading to shock and coma. Specific methods:
1, first move to a safe or quiet place, check the injury and determine the nature of bleeding, such as arterial bleeding, venous bleeding and capillary bleeding;
2. You can directly press the bleeding wound or bleeding artery with your fingers to stop bleeding;
3. In case of limb injury and bleeding, you can wrap it with a belt, tie, ID tape, coarse cloth strip and silk scarf, or tear it into strips with clothes instead, and tie the upper arm 1/3 or the middle thigh to stop bleeding.
(2) Fixation
Fixing fractures and joint injuries aims to avoid new injuries caused by fracture ends, relieve pain and facilitate treatment and rescue. Specific methods:
1, the open wound should be bandaged first and then fixed, and don't try to send the punctured fracture end back;
2. Cushion or raise the injured part to slow down bleeding and reduce swelling;
3. Do not move the injured or suspected injured spine;
4. When fixing, the upper and lower joints at the fracture end must be fixed together. For example, the ankle and knee joint should be fixed for a calf fracture.
(3) Shock first aid
1, in order to prevent the injured from being too cold or too hot, you can use blankets or coats to keep warm;
2. If there is no fracture, raise the injured person's foot by about 30 cm;
3. Don't drink water and don't feed the injured;
4, pay attention to the consciousness of the injured;
5, report to the ambulance personnel.
3. Some misunderstandings of first aid.
Myth 1 Move the weak at will.
Sudden fainting may be anemia, hypoglycemia, cerebral hemorrhage or heart discomfort. At this time, enthusiastic people should not shake, help or move patients at will when the situation is unknown.
The correct first aid method: observe the patient's complexion, check the pulse and breathing, and call the patient's name loudly at the same time to see if there is any response. If there is a reaction, it is a shallow coma. Try to pinch someone. If there is no breathing or wheezing, the patient should keep pressing hard and quickly between the nipples without mouth-to-mouth blowing, and ask someone to call 120. Coma patients should avoid lying on their backs and lie on their sides to prevent suffocation caused by oral secretions and vomit inhaled into the respiratory tract. Be careful not to give food or water to comatose patients.
Of course, we still advocate to find professionals to rescue quickly, otherwise it may backfire because of the wrong disposal method, causing secondary injuries.
Myth 2: nosebleeds, watching the sky
Many people with nosebleeds will hold their heads high to avoid nosebleeds. Some people also use paper towels to block their nostrils.
The correct first aid method: hold your nose, let the patient lean forward and breathe through your mouth. Pinching your nose can promote blood coagulation, and you can also use cold water or ice to compress your nose. Don't let the patient lean back. Although this seems to be correct, if the blood flow is large, leaning back may cause blood to flow into the airway and block it, or blood to flow into the stomach, causing the patient to vomit. If the trauma causes massive bleeding, you can press the external carotid artery in front of the ipsilateral masseter muscle. When the nosebleed can't stop, you should call 120 or ask others for help as soon as possible.
Misunderstanding three joint sprains hot compress to dissipate blood stasis
Nowadays, people pay great attention to exercise, and it is inevitable to sprain their joints when playing ball and running. Rubbing by hand, applying hot towels and sticking plasters are all common practices.
The correct first aid method: remember the rice principle-rest, fixation, cold compress and raising the injured limb. Hot compress or alternating hot and cold treatment is not recommended. Cold compress is the most effective way to reduce edema.
It is best to use only cold water for joint sprain, and hot compress will cause the wound to swell more seriously. Hot compress can only be performed after 24 hours of wound treatment. At this time, it has the function of promoting blood circulation and removing blood stasis, so it is not recommended to use plaster in on-site first aid.
Myth 4: Eat with fishbone and big mouth.
In daily life, when eating, we are often accidentally caught by fishbones, bamboo sticks, chicken bones, duck bones, etc. Some people are used to swallowing rice balls, steamed bread, baked steamed bread slices or vegetable balls in an attempt to squeeze fishbone into their stomachs. This method sometimes backfires and aggravates local tissue damage.
The correct first aid method: the throat is mostly located in tonsil, tongue base, epiglottis and so on. At this time, most of them have tingling or aggravated pain when swallowing, which affects eating. For children, large foreign bodies can also cause dyspnea and asphyxia, which should be actively dealt with:
1. Ask the patient to open his mouth, gently press his tongue with chopsticks or spoon handle to expose the base of his tongue, and illuminate it with a flashlight to see if there are foreign bodies such as fishbones. For example, tweezers can sometimes be used to clip out foreign objects.
2. If the patient realizes that the fishbone is around epiglottis or esophagus and it is difficult to take it out, it is better to see a doctor.
Myth 5 Burn and scald with soy sauce and sesame oil
When cooking at home, I accidentally got burned. Although it hurts, many people feel that it is not cost-effective to go to the hospital because of the small area, so they find something to apply to relieve inflammation and pain. Commonly used are soy sauce, sesame oil, toothpaste, aloe, safflower oil, egg white, honey and so on.
The correct first aid method: rinse the burned area with flowing cold water for at least 10 minutes, and send the severe cases to hospital for treatment. Don't apply grease, ointment and other items, and don't use ice cold compress. Ice cubes may further damage the skin.
The application of ointment for burns and scalds is taken in the follow-up treatment, and it is best not to use all kinds of ointment or grease in the field first aid stage. Because grease can prevent heat from emitting and make the burn more serious, if you apply something, you must remove it when you go to the hospital for debridement. It should be noted that after burns, never break the blisters on the skin to prevent infection.
Myth # 6: When a foreign object enters your eyes, rub it hard.
Any tiny object or liquid, even a grain of sand or a drop of detergent, will cause eye pain. Some people subconsciously rub their eyes hard, thinking that they can get things out of their eyes as soon as possible.
Correct first aid methods: First, blink frequently and forcefully, and wash the foreign body out with tears. If not, pinch your eyelids and rinse your eyes under current. Be sure to take off your contact lenses.
Never rub your eyes, no matter how small the foreign body is, it will scratch the cornea and cause infection. If a foreign body enters the deep layer of the eye or corrosive liquid spills into the eye, be sure to seek medical attention immediately. Acidic liquid will be diffused by water, so don't wash it yourself.
Myth 7: Food poisoning, vomiting quickly.
After eating poison, people think that spitting it out will reduce the degree of poisoning, so many people put their fingers, chopsticks and tongue depressors in their mouths to induce vomiting.
Correct first aid: Don't induce vomiting or let the patient drink anything, inducing vomiting may cause more damage to the patient's throat or block the airway. If the patient swallows something corrosive, the liquid backflow will further burn the throat, causing pain and discomfort. You should call 120 as soon as possible to know immediately what, when and how much the poisoned person took, so as to prepare for the arrival of professional emergency personnel.
Myth 8: Acute pain, eating painkillers indiscriminately.
Abdominal pain, joint pain, toothache, headache, many people will encounter this kind of pain, and in severe cases there will be unbearable pain. At this time, painkillers often become the drugs that patients want most.
Correct first aid method: avoid using painkillers when the cause is unknown, so as not to cover up the illness and delay the diagnosis. Patients should go to the hospital for examination as soon as possible when the pain is aggravated. Some abdominal pains and headaches can be life-threatening.
