Recently, I watched an excellent movie, "The Revenant," and was immersed in Leonardo DiCaprio's self-defence skills. Indeed, in the wild, once the accident, the injured can not be fast, comprehensive urban medical assistance, it could mean disability or even death, limited resources, the harsh natural environment is exacerbated by the unique nature of the field of first aid. So, if you loved and often outdoor sports, have some common outdoor first aid knowledge and prepare an outdoor first-aid kit is still very necessary.The Revenant

Three principles for dealing with outdoor injuries

1.Don't endanger the rescuers and other members involved in the rescue.

2. If the rescuer is not a certified physician, he will not do anything beyond the limit.

3. The treatment should aim at preventing further deterioration of the injury, facilitating handling, and additional rescue.


Common outdoor injuriesFracture

Fracture

Symptom judgment

Analyzing from injury symptoms: If the severe wound pain, local swelling significantly, severe subcutaneous congestion, bruising, and the appearance of deformities occur, the possibility of fracture on a lot. And the wound will only swell after a while, and it may be sprain and dislocation.

Dysfunction at the wound: After the fracture, the limb will lose part or all of its function. After a broken arm, the grip of the hand is not good enough to lift things; after a fractured lower limb, you cannot stand or walk; after a broken waist, you cannot sit.

 Fracture- Symptom judgment

Analyzing from injury symptoms: If the severe wound pain, local swelling significantly, severe subcutaneous congestion, bruising, and the appearance of deformities occur, the possibility of fracture on a lot. And the wound will only swell after a while, it may be sprain and dislocation.

Dysfunction at the wound: After the fracture, the limb will lose part or all of its function. After a broken arm, the grip of the hand is not good enough to lift things; after a fractured lower limb, you cannot stand or walk; after a broken waist, you cannot sit.


2.Bandage

If there is no splint available on site, the injured limb and the first leg can be aligned side by side and wrapped around and fixed.

Spine fractures: Spine fractures are often in serious condition, and it is strictly forbidden to move around without fixation. After the injured person lay supine, use sandbags to place both sides of the head to immobilize the neck to prevent permanent paraplegia caused by the displacement of the fracture and compression of the central nervous system.

Fracture of arm: Put the wooden board with cotton pad first, put it on the front and back of the wounded arm, wrap it with cloth tape, and then hang it with a triangle towel or clothing. If the upper arm is fractured, the arm flexes when hanging, and the elbow flexes 90 ° when the forearm fractures, and then swings.

Bandage


Lumbar vertebrae fracture: Lay the injured person on a hard board and fix the lumbar spine and lower limbs together. 

Precautions:Use a bandage to fix the fracture, which can prevent the damage of the fractured end to the blood vessels, nerves, and other tissues and cause complications. The length of the fixed splint should be higher than the upper and lower joints of the fracture, and if there is bleeding, stop bleeding, clean, and disinfect before bandaging.

 

3.Trauma

Trauma

Open wound: First, rinse the wound with clean water so that it is free of foreign objects. Try to use the boiling water in the kettle to clean the water source. If alcohol or iodine is present, apply to rub to the skin around the bleeding site and apply antibiotic ointment or cream locally. Usually, doctors recommend exposing the wound to dry it for natural healing. Still, for severe injuries, it must be sent to the hospital for debridement and suture as soon as possible.

Closed wound: For such wounds, the main points of field first aid are pressure bandaging and cold compress. Pressure bandaging can increase political pressure and prevent the bleeding of broken blood vessels at the injury site to reduce the amount of bleeding. The purpose of the cold compress is to freeze or even close the local blood vessels through cryotherapy to minimize bleeding.

Generally speaking, within 6 hours of injury, compression bandage and cold compress are the main methods. We should note that illegal practices, such as local massage and hot compress, will lead to increased bleeding. Minimize excessive local exercise and lift as much as possible—profoundly affected limb.

 

4.Poisoning

Snakebite poisoning

Stopping activities: When a venomous snake bites a limb, it must immediately stop the movement of the injured limb, do not exercise vigorously, reduce the spread of venom with the blood, and place the injured leg at the lowest position.

Banding: Try to use the tourniquet in the first-aid kit to bind about 10 cm above the wound (near the heart) or the corresponding part of a joint on the injury within 2-3 minutes to reduce the absorption of the snake venom caused by blood backflow. But it can't be tied too tight, and it needs to loosen every half a small clock, about 2 minutes each time, so as not to affect the blood circulation and cause tissue necrosis.

To clean up the wound: Use clean water, cold water, and salt or soapy water to rinse the injury, and use a knife to make a cross-shaped mouth at the wound to let the poisonous blood flow out. If necessary, you can use your mouth to suck out the wound toxins, but you must rinse your mouth in time. If the mouth is damaged, do not, and seek medical treatment as soon as possible.first aid kit


5.Ingestion of plant poisoning

Induced vomiting: The fastest is to use your fingers, press the base of the tongue, and touch the tonsils of the pharynx. You can try to squeeze the position below the stomach with both hands, or pat the area of the abdomen back.

Detoxification: After first aid treatment, the antidote can take if possible. The most troublesome can eat raw egg whites, raw milk, mainly to absorb or neutralize alkaloids, outdoor heavy metals and acids, and other poisons.


When implementing first aid in a wild environment, the most important thing is to determine the severity of the problem on time and handle it reasonably promptly, while preventing secondary injuries. It is crucial to keep in mind that prepare one outdoor first aid kit and be sure to check the basic vital signs of the injured first (three critical systems for quick examination of the injured person)-circulation, breathing, and nervous system must check first. Be aware that any significant problems related to these three meaningful systems can endanger the lives of patients.
