Personal fall injury rescue knowledge

1. First aid methods for falls

1. First aid methods for falls: scrapes and scrapes are the most common injuries.

Under normal circumstances, just wipe away the dirt and blood from the wound with warm water without bandaging. Only when the injury is more serious does it need to be disinfected and a band-aid or trauma plaster applied.

2. First aid method for injuries caused by falls: Injury to tendons is caused by overburdening the muscles. The pain worsens when bearing weight.

Cool down the injured area immediately (it is best to apply ice for 30 to 60 minutes). An hour delayed in first aid means an extra day of treatment.

The injured person must stop exercising for at least a week. 3. First Aid Methods for Fall Injuries: Bruises and bruises are caused by kicks - such as when playing football - or violent collisions.

They can cause subcutaneous blood vessels to rupture, causing blood to flow into surrounding tissues, resulting in a purple spot. Immediately cool down the injured area and wrap it with an elastic bandage if possible. 4. First aid for falls: fractures. Fractures generally have symptoms such as pain, swelling, deformity, and dysfunction. When the fracture end punctures a large blood vessel, there may be heavy bleeding.

When a fracture or suspected fracture occurs, avoid moving the injured person or injured limb, and fix and support the injured limb (if there is bleeding, the bleeding should be stopped first and then fixed) so that the injured person will not be moved during transportation. , bumps can cause broken bones to puncture blood vessels and nerves, preventing additional damage and aggravating the condition. 5. First aid methods for falls. For minor craniocerebral trauma, concussion is generally not required. There is generally no skull fracture, mild headache and dizziness, and coma for less than 30 minutes.

Severe cases include skull fracture, brain contusion, cerebral hemorrhage, and coma. right.

Patients with craniocerebral trauma must race against time to notify the hospital for timely rescue. They must stay quiet in bed, avoid unnecessary moving and inspection, and keep their respiratory tract open. 6. First aid method for falls: Cervical vertebrae injuries. Falls can cause injuries to the lumbar, thoracic, and cervical vertebrae, with the latter being the most serious. For example, falling on the head can cause cervical vertebra dislocation and fractures, often accompanied by spinal cord injury and quadriplegia.

The hospital must be notified as soon as possible to come for rescue as soon as possible. During on-site first aid, the injured person should be asked to lie down on the spot or placed on a hard wooden board. Sandbags should be filled on both sides of the neck to keep the cervical spine in a stable state. Keep the axis of the cervical spine consistent with the thoracic spine. Do not hyperextend, flex, or rotate.

4. First aid for falls and fractures

Fractures generally have pain, swelling, deformity, and dysfunction. Symptoms include severe bleeding when the fracture end punctures a major blood vessel. When there is a fracture or a suspected fracture, avoid moving the injured person or injured limb, and fix and support the injured limb (if there is bleeding, stop bleeding first and then fix it), so that the injured person does not have bone spurs caused by handling and bumps during transportation. Damage blood vessels and nerves to avoid additional damage and aggravate the condition.

5. First aid for falls: craniocerebral trauma

Mild cases include concussion, usually no skull fracture, mild headache and dizziness, and coma lasting no more than 30 minutes. Severe cases include skull fracture, brain contusion, cerebral hemorrhage, and coma. right. Patients with craniocerebral trauma must race against time to notify the hospital for timely rescue. They must stay quiet in bed, refrain from unnecessary movements and inspections, and keep their respiratory tract open.

6. First aid method for falls: cervical spine injuries

A fall can cause injuries to the lumbar spine, thoracic spine, and cervical spine, with the latter being the most serious. For example, if your head hits the ground when you fall, it can cause cervical spine injuries. Dislocations and fractures are often accompanied by spinal cord injury and quadriplegia. The hospital must be notified as soon as possible to come for rescue as soon as possible. During on-site first aid, the injured person should be asked to lie down on the spot or placed on a hard wooden board. Sandbags should be filled on both sides of the neck to keep the cervical spine in a stable state. Keep the axis of the cervical spine consistent with the thoracic spine. Do not hyperextend, flex, or rotate.

3. What is the knowledge about first aid for injuries during travel?

When traveling, especially if you choose to travel during the Golden Week, you will always encounter a huge crowd of people. At this time, Bumps and bruises happen from time to time. What should you do if you are accidentally injured, so travel friends still need to learn some basic first aid knowledge.

Head injuries

If you collide with others or fall and hit your head and get a big bump, you may not need to worry too much, but if you have high fever, vomiting, cramps or clear discharge If your body fluids (serum, cerebral effusion) are present, you should be sent to the hospital as soon as possible.

1. In addition to the swollen areas, other parts of the head should also be treated with cold compresses. However, when there is a wound, it cannot be treated in this way to avoid encouraging bacterial growth.

2. If bleeding or clear liquid (serum, cerebral effusion) flows from the ears, nose or mouth, tilt your face in the direction of the flow. Be careful not to plug it with gauze or other things to avoid bacterial infection.

3. When vomiting, place your head sideways to prevent vomitus from becoming blocked.

4. When spasm occurs, do not arbitrarily compress the injured limb. Roll a handkerchief into a tube and stuff it in the patient's mouth to calm it down.

5. When carrying the injured, the head should be fixed and not shaken.

Injured neck

1. There are trachea, esophagus and nerves in the neck, which are important parts of the human body. If you are hit, you should be sent to the hospital as soon as possible

2. In order to inhibit internal bleeding, a cold compress must be applied to the impact area.

3. When external bleeding is found, apply sterile gauze to the wound to stop bleeding.

4. When lying down, keep your body flat and never use pillows.

5. Keep your head fixed when moving.

Back bruises

1. Let the injured person lie on his back on a hard wooden board, and place pillows on the neck and waist respectively to maintain the natural curvature of the spine. No sitting or cross-legged postures are allowed.

2. When moving, the neck must be fixed at the same time, and the lying board must be avoided from shaking when transporting.

Chest injury

1. If the chest is hit, there is a risk of fracture or difficulty breathing. You should go to the hospital as soon as possible.

2. Cold compress treatment.

3. Let the patient lie quietly on the thick quilt, with the chest on the painful side facing down.

This answer comes from the official website of Extreme Outdoor Network

4. First aid knowledge

1. Treatment of small area burns and scalds Small area mild burns and scalds, local If the skin becomes red, you can immediately cool down and rinse with tap water, or soak the burned area in clean cold water for about 30 minutes. You can also use cold compresses, such as ice cubes.

If you are wearing clothes when being burned, you need to cool down first before taking off your clothes. Otherwise, the free epidermis after burns and scalds will be torn off together with the clothes, causing serious consequences. In addition, if there are blisters in the burn area, be sure not to open or break them, and do not apply red liquid, purple liquid, or even soy sauce and other items, as these are extremely detrimental to later treatment.

Severe burns and scalds must be treated in the hospital promptly. 2. Treatment of Sudden Cerebral Hemorrhage For patients with cerebral hemorrhage, family members should try to restrain their emotions and call the emergency number in time.

Never shout, cry, or move or jolt the patient. The environment around the patient should be kept quiet and away from light to reduce noise exposure. At the same time, a dedicated person should be supervised to prevent the patient from falling off the bed due to restlessness. The patient should be placed in a supine position with his head tilted to one side and no pillow behind him.

Untie the patient's collar, wrap the patient's tongue with gauze and pull it out to remove mucus, secretions and vomitus from the mouth to keep the airway open. Apply an ice pack or cold water towel to the patient's forehead to cool down the head to facilitate hemostasis and reduce oxygen consumption in the brain; move the patient gently, and the patient's oral secretions, sputum and other foreign matter must be continuously removed during the process to keep the airway open.

3. Treatment of electric shock When an electric shock occurs, every second must be used to provide first aid to the injured. When rescuing, you should first observe, turn off the switch, cut off the power supply, and ensure safety before proceeding.

When the power cannot be turned off, you can use wooden sticks, bamboo poles, etc. to lift the wire away from the body of the person who received an electric shock. If you cannot remove wires or other live electrical appliances that may cause electric shock, wrap a dry rope around the person who gets the electric shock and drag them away from the power source.

Before cutting off the power supply, rescuers should not use their own hands to pull the electrocuted person directly, otherwise they themselves will be in danger of being electrocuted immediately. It is best for rescuers to wear rubber gloves and rubber sneakers. When the injured person is disconnected from the power source, the general condition of the injured person should be checked immediately. If breathing and heartbeat are found to have stopped, cardiopulmonary resuscitation should be performed immediately on the spot.

For patients with mild symptoms who are conscious, the injured should lie down on the spot and be closely observed. Do not stand or move for the time being to prevent secondary shock or heart failure. For those who have stopped breathing and heartbeat, external chest cardiac compressions should be performed while artificial respiration is performed to establish breathing and circulation and restore the oxygen supply to the organs throughout the body.

At the same time as rescuing, call for help quickly and notify 120. If the heartbeat and breathing have not recovered, rescuing cannot be stopped on the way. 4. First aid knowledge for family accidents In family accidents, incorrect first aid often leads to the opposite direction and makes things worse.

The following common erroneous rescue methods should be avoided: Avoid using painkillers for acute abdominal pain to avoid masking the condition and delaying diagnosis. Go to the hospital for a check-up as soon as possible. Do not send back the prolapsed viscera immediately due to trauma to the abdomen. The prolapsed viscera must be thoroughly disinfected by a doctor before being sent back.

To prevent serious consequences of infection. Do not use a tourniquet for ligation for too long. The tourniquet should be relaxed for 2-3 minutes every 40-50 minutes, and records should be kept to prevent ischemia and necrosis of the distal limb caused by ligation for too long.

Comatose patients should not lie on their backs. They should lie on their sides to prevent the tongue from falling back and oral secretions and vomitus being inhaled into the respiratory tract, causing suffocation. It is even more forbidden to give food or water to comatose patients.

Patients with cardiac asthma should avoid lying on their backs because lying on their backs will increase blood stasis in the lungs and burden on the heart, aggravating asthma and endangering life. You should take a semi-recumbent position so that your lower limbs hang down.

Patients with cerebral hemorrhage should not move them at will. If there is a sudden fall during activities, a coma or a paralyzed person who has suffered from cerebral hemorrhage, they are likely to have cerebral hemorrhage. Moving them at will will make the bleeding more serious, so they should lie down. Turn your head to one side, raise your head, and send him to the hospital immediately. Small and deep wounds should not be bandaged carelessly. The lack of oxygen in the wound will lead to the growth of anaerobic bacteria such as Tetanus bacillus. The wound should be debrided and disinfected in the hospital before being bandaged and injected with tetanus antitoxin.

Patients with diarrhea should avoid taking antidiarrheal drugs indiscriminately. Using antidiarrheal drugs indiscriminately before the inflammation is reduced will make it difficult to excrete toxins and aggravate intestinal inflammation. Anti-diarrheal medications should be used after anti-inflammatories.

Do not try to rescue someone who gets an electric shock with bare hands. If you find someone getting an electric shock, you should immediately cut off the power supply, or use dry wooden sticks, bamboo poles and other insulators to open the wires. 5. Treatment of Drowning Drowning is caused by a large amount of water pouring into the lungs, or laryngospasm caused by cold water inhalation, resulting in suffocation or hypoxia. If the rescue is not timely, death can occur within 4-6 minutes.

Therefore, we must race against time to provide on-site first aid and dial 120 at the same time. First aid methods: 1. After lifting the casualty out of the water, immediately remove water, mud and dirt from the mouth and nose, wrap your fingers with gauze (handkerchief), pull the casualty's tongue out of the mouth, and unbutton and collar the casualty. , to keep the respiratory tract open, and then pick up the waist and abdomen of the wounded person, with his back facing up and his head drooping, to pour water.

Or pick up the legs of the injured person, put his abdomen on the shoulders of the first responder, and run quickly to pour out the accumulated water. Or the first-aider can take a half-kneeling position, place the injured person's abdomen on the first-aider's legs, let his head droop, and use his hands to flatten his back to pour water.

Pay attention to the short time. 2. Those who have stopped breathing should immediately perform artificial respiration, usually with mouth-to-mouth blowing.

The first responder is located on the side of the casualty, holds the casualty's chin, pinches the casualty's nostrils, takes a deep breath, and slowly blows air into the casualty's mouth. When the chest is slightly lifted, relax it. nostrils, and press his chest with one hand to help exhale. Do this repeatedly and rhythmically (12 blows per minute) until breathing is restored.

3. Those with cardiac arrest should undergo external cardiac surgery first. Let the injured person lie on his back on a flat and hard surface. The first aid provider is on one side of the injured person. Facing the injured person, his right palm is placed flat on the lower half of his sternum, and his left hand is placed on the back of his right hand. Use the first aid person's body weight to apply force slowly, but not too hard. To prevent fracture, press down the sternum by about 4-5 cm, then release the wrist (without leaving the hand from the sternum) to restore the sternum, repeat rhythmically (100 times per minute) until the heartbeat recovers.

4. If the heartbeat and breathing have stopped, the above two items should be performed at the same time. First blow two breaths and perform 30 chest compressions as a cycle.

The ratio of breathing to chest compressions is 2:30. Do it for five consecutive cycles, and then judge whether your breathing and heartbeat have recovered. If so, you can stop doing it.

If there is no recovery, continue for five cycles. Wait for medical professionals to arrive.

6. Treatment of injuries caused by firecrackers Firecrackers are the most characteristic thing of the Spring Festival, and they are also the favorite thing for children to play during the Spring Festival. In recent years, with the firecrackers.

5. First aid measures after injury

Let me give you a simple method. Let me first talk about the characteristics of stab wounds: the wound is small but deep, and the punctured object is not clean and can easily lead to stab wounds. Breeds anaerobic bacteria.

1. According to the characteristics of stab wounds, the entrance is small and the depth is deep. Such wounds require tetanus shots, which can only be given to the hospital within 24 hours. 2. Disinfection and anti-inflammation: It is recommended to prepare a small bag with you. Necessary: ??1) Disinfectant: iodophor (you can prepare iodophor cotton, but it must be updated regularly), Revnol strips, 2) Conventional anti-inflammatory drugs such as: Cephalexin and gentamicin (ground into powder can be applied to wounds, or taken orally to reduce inflammation). 3) For dressing, just prepare gauze and band-aid.

3. Let’s talk about the actual specific operations after stabbing. 1. Debridement and hemostasis: After a stab wound, the first step is to clean the wound in time to stop bleeding. No matter whether the wound hurts an artery or a vein, debridement and hemostasis are the first step. The blood in arteries and veins can be distinguished by their color. Arterial blood is brighter red. The venous blood is dark. When the blood volume of the outgoing artery is large, tie the proximal end of the limb with a rope. When the vein bleeds, tie the distal end to prevent excessive blood loss. Then simply bandage it and go to the hospital.

If the amount of bleeding is not large, it can be washed with hydrogen peroxide, disinfected with iodine, and then applied with a strip soaked in Revnol. After bandaging, go to the hospital for tetanus. 2. Anti-inflammation and anti-infection. Deep wounds are prone to infection. At this time, you need to take oral anti-inflammatory drugs for about 7 days! 4. Recovery.

1. Make sure the wound is clean and disinfected with iodophor. 2. Ensure sleep and rest.

3. Dietary taboos are only required for deep trauma. I would like to tell you that if necessary, you should avoid these things according to your own situation. Avoid tobacco and alcohol, spicy food and hair, trauma. The taboo is because the harmful factors in these foods will cause the wound to accelerate blood flow, cause infection symptoms, and leave larger scars. In fact, it is not serious. 4. Try not to get water on the wound. If there is anything else I didn’t expect, I will look back and think about it, and that should be it! In fact, there is nothing difficult or complicated. As long as you ensure timely disinfection and anti-inflammation, there will be no big problem.

6. How to provide first aid for injuries caused by a fall from a height

The methods for providing first aid for injuries caused by a fall from a height are as follows: (1) The injured person who fell to the ground should be initially examined for injuries. Do not move or shake the object randomly. Call 120 emergency doctors immediately for treatment.

(2) Take initial rescue measures: stop bleeding, bandage, and fixate. (3) If spinal fracture is suspected, follow the handling principles for spinal fractures.

The spinal bones include cervical vertebrae, thoracic vertebrae, lumbar vertebrae, etc. If the injured people with spinal fractures are not treated properly in on-site first aid, the pain will increase and irreparable consequences will occur. Especially after the back is hit by an object, there is a possibility of spinal fracture.

During first aid, wooden boards or stretchers can be used to carry the injured person, so that the injured person can lie on his back. When there is no stretcher or the board needs to be carried by multiple people, one of the rescuers must hold the waist of the injured person with both hands. It is strictly forbidden for one person to rescue the injured by pulling or dragging alone.

If the spinal nerve of the injured person is severed, it will cause serious consequences of permanent paralysis of the lower limbs. It is also not allowed to carry the injured with one person holding the chest and another holding the legs; when the injured is getting on and off the stretcher, 3 to 4 people should hold the head, chest, buttocks and legs respectively to keep the movements consistent and smooth to avoid bending and twisting of the spine, which will aggravate the injury.

7. How to provide first aid for daily injuries

General first aid principles When providing first aid to a person who has been injured by a chemical, the first few emergency treatments to be done are: -- Remove the unconscious person The patient is placed in a lateral position to prevent airway obstruction, and oxygen inhalation is provided when breathing is difficult; artificial respiration is performed immediately when breathing stops; external thoracic heart compression is performed immediately for patients with cardiac arrest.

--When the skin is contaminated, take off the contaminated clothes and rinse with running water; when the head and face are burned, pay attention to cleaning the eyes, ears, nose, and mouth. --When your eyes are contaminated, immediately lift your eyes and face and rinse them thoroughly with plenty of running water for at least 15 minutes.

--When people suffer from frostbite, they should be quickly rewarmed. The method of rewarming is to soak in constant-temperature hot water at 40°C to 42°C to increase the temperature to close to normal within 15 to 30 minutes.

When performing gentle massage on frostbitten areas, care should be taken not to scratch the skin of the injured area to prevent infection. --When a burn occurs, the patient should quickly take off his clothes, rinse with water to cool down, and cover the injured surface with a clean cloth to avoid contamination of the injured surface; do not burst blisters at will.

When patients are thirsty, they can drink an appropriate amount of water or salty drinks. --For oral administration, symptomatic treatment can be carried out according to the nature of the material; gastric lavage is necessary.

--After on-site treatment, they should be quickly escorted to the hospital for treatment. Remember: Use mouth-to-mouth resuscitation and flush contaminated skin or eyes to avoid further injury.

Precautions for on-site first aid - When performing first aid, both the patient and the rescuers need to wear appropriate protection. This is very important! Especially when rescuing patients from severely contaminated sites, rescuers must take precautions to avoid becoming new victims.

--The injured person should be carefully moved from the dangerous environment to a safe location. --At least 2 to 3 people should act in groups to monitor and care for each other. The rescue equipment used must be explosion-proof.

--Routine first aid treatment, the following steps can be taken: first remove contaminated clothing of the sick and wounded ------ then rinse ------permanent treatment---- --Individual treatment------Transfer to hospital. --Treat pollutants.

Pay attention to the handling of contaminated clothing from injuries to prevent secondary damage.

8. How to provide first aid for falls and strains

Mild falls can lead to abrasions, contusions and lacerations of the skin or soft tissue in contact parts with the ground or walls, etc. It can cause tears, dislocations or even fractures of local joints, ligaments, tendons, nerves, blood vessels and other structures. Severe falls can cause secondary shock, embolism, craniocerebral injury, hemopneumothorax, abdominal organ rupture, spinal fractures, etc. Damage may even lead to coma, paraplegia, or life-threatening injuries.

Therefore, when a fall or strain occurs, the severity of the injury should be initially judged, and appropriate first aid treatment should be carried out to reduce the injury, so as to avoid secondary injuries and serious life-threatening situations. . Life-threatening dangerous situations should be eliminated first, such as coma, projectile vomiting, suffocation, etc. The respiratory tract needs to be cleared in time, do not move easily, and request professional rescue.

Then pay attention to determine whether there are any fractures and large blood vessel injuries in the injured area.

Severe pain in the limbs, rapid congestion, deformity, etc. often mean fractures; if a limb fracture occurs, the injured limb should be immobilized. If a spinal fracture is considered, spinal flexion and twisting should be strictly prohibited, and try to wait for the "120" emergency personnel to arrive at the scene to avoid Spinal fractures lead to paraplegia.

If there is blood gushing out from the wound, it means that the artery or large vein is damaged. You can wrap the proximal end of the wound or flex the joint to stop the bleeding, or apply pressure to the wound to stop the bleeding. If there is an open wound after a fall, regardless of the size of the wound, you should be sent to the hospital for treatment and injection of tetanus antitoxin.

Before arriving at the hospital, or while waiting for rescuers, stop bleeding in time and wrap the wound with sterile gauze or clean cloth. 6 to 8 hours is the best time for wound treatment and suturing, and must not be delayed.

Muscle strain is a muscle tissue that is subjected to strong external force and causes injuries such as rupture, bleeding, and edema of varying severity. Severe strains should be examined in the hospital to rule out fractures and complete rupture of muscles or tendons. After waiting for the situation, you can use ice cubes or cold water to apply cold compresses in the early stage of the injury to reduce local bleeding and edema. Two days later, you can use hot compresses to promote the dissipation of local congestion and edema. When going out in cold weather, joints tend to become stiff and uncoordinated, and there may be snow and ice on the ground. You need to pay special attention to your feet to prevent falls.

Before exercising and exercising, you need to make sufficient preparations to move your joints and increase coordination. While exercising.

Try to avoid impacts and falls. If you fall, you should learn from the movements of football players and use your body to roll to unload the impact. Don't fall too stiffly to the ground.

Pay attention to supplementing calcium and vitamin D in daily life to increase the body's extensibility and coordination, enhance joint flexibility and mobility, and also reduce the harm of falls and strains.

9. Do you know the knowledge about first aid for injuries during travel?

1. Neck injury 1. There are trachea, esophagus and nerves in the human neck, which is one of the important parts of the human body. 1. If you are hit, you should be sent to the hospital as soon as possible.

2. In order to inhibit internal bleeding, a cold compress can be applied to the impact area. 3. If external bleeding is found, you can use sterile gauze to compress the wound to stop the bleeding.

4. When lying down, keep your body flat and do not use pillows. 5. When moving, be sure to keep your head fixed.

2. Back Injury 1. Let the injured person lie on his back on a hard wooden board, and use pillows to cushion his neck and waist to keep the spine in a natural curve. No sitting or cross-legged postures are allowed.

2. If it is to be moved, the neck must also be fixed at the same time, and the lying board must be avoided from shaking when carrying it. 3. Chest injuries 1. Chest injuries caused by impact may lead to the risk of fractures or difficulty breathing. You must be sent to the hospital as soon as possible.

2. Apply cold compress to the injured and painful area first. 3. Be sure to soothe the patient and let him lie quietly on the thick quilt, with the chest on the painful side facing down.

4. Head injury 1. If you collide with others or fall and hit your head, you may not need to worry too much. However, if you have high fever, vomiting, convulsions or the discharge of clear body fluids (serum , cerebral effusion), you need to be sent to the hospital as soon as possible. 2. In addition to the swollen area, other parts of the head should also be treated with cold compresses.

However, when there is a wound, it cannot be treated in this way to avoid encouraging bacterial growth. 3. If bleeding or clear liquid (serum, cerebral effusion) flows from the ears, nose or mouth, tilt your face in the direction of the flow.

Do not use gauze or other things to plug it to avoid bacterial infection. 4. When vomiting, place your head sideways to prevent vomitus from getting stuck.

5. When spasm occurs, do not press the injured limb arbitrarily. Roll a handkerchief into a tube and stuff it in the patient's mouth to calm it down. 6. When carrying the injured, the head should be fixed and not shaken.

10. What are the simple first aid methods when people are injured in an accident?

For injuries, the most important thing is to use trauma first aid techniques according to the specific situation. .

When the casualty bleeds severely, choose different hemostasis methods (including compression hemostasis, tourniquet hemostasis, etc.) Bandaging treatment; when the patient is seriously injured and unable to move around on his own, he needs to be transported by the rescuer; some critically ill patients may have cardiac and respiratory arrest and require cardiopulmonary resuscitation. But at the same time, it should be noted that since the scene of an emergency is often not safe, you must always pay attention to the safety situation on the scene and evacuate immediately if necessary; in addition, it is also very important to call "120 (and call 110 and 119 as needed)" in a timely manner of.
