Survival on the Island starts with a female boss

Chapter 30 Field Emergency Rescue Methods

Ma Yongqiang suddenly thought of the injury when he was a child. When he was naughty and injured when he was a child, if a small wound was cut and bled, he would usually smear the wound with saliva, feeling that saliva has the function of anti-inflammatory and sterilizing.

He and Yu Tina explained in detail how they used saliva to smear wounds when they were young. In Ma Yongqiang's understanding, saliva can effectively prevent wound infection.

Of course, after Yu Tina's system standard explanation, Ma Yongqiang decided to give up this unrealistic idea, after all, Yu Tina's original words were like this.

Saliva contains cell-derived tissue factor—a protein necessary to activate thrombin, which plays an important role in blood clotting—and certain enzymes: such as lysozyme, cysteine ​​protease, peroxidase, and Defensins - These all have antimicrobial properties.

In a study published in 2008, scientists discovered that small proteins called histamines, present in saliva, help heal trauma.This may be one explanation for the faster healing of oral mucosa and oral wounds (caused by teeth) than bone and skin wounds.

This is also the most basic explanation for animals licking their wounds with their tongues in the animal world, because sometimes the most instinctive nature of animals will choose the most effective solution.

In addition, licking smaller wounds can also help with debridement (removal of damaged, dead, or infected tissue from the area affected by the wound) and effectively decontaminate the specific area.

So after Yu Tina's explanation, although it may be very effective, Ma Yongqiang said very simply that this method should not be used.

Of course, the main reason Ma Yongqiang admitted to the outside world is that although human saliva does contain some compounds that are helpful for healing, the oral cavity is also the host of many bacteria. These bacteria are very safe in the oral cavity, but if they are introduced into the deep In the wound, serious injury will be caused.

Of course, Ma Yongqiang will never admit it, because after listening to Yu Tina, he needs to use his tongue to clean up the wound, which looks so disgusting, and it is not his own. Mouth full of pustules, vomit...!
I couldn't help complaining fiercely, it's a human thing!

Yu Tina saw Ma Yongqiang shaking his head and gagging with a funny expression.Jean Yu Tina couldn't help covering her mouth and laughing out loud.

Of course, after such a long time of thinking and analysis, Yu Tina probably came up with a simple and effective plan based on the simple professional first aid knowledge she had learned.

So he straightened his expression, and explained the matter to Ma Yongqiang in detail. What he thought in his heart was a relatively effective first aid plan for the moment.

In the wild, if unfortunate enough to receive a pioneering wound.

Under normal circumstances, the wound should be kept clean first. When conditions permit, it is best to use pure water, or at least boil water on the fire and let it cool.Rinse the wound with clean water to maintain the hygienic conditions inside the wound, and prevent the wound from being mixed with unclean impurities, causing unnecessary troubles, and even inflammation and festering.

If the wound area is relatively large and the bleeding continues, you can use red-hot charcoal or metal products to first conduct an emergency carbonization of the wound to stop bleeding.

Generally, this situation is more common in some film and television dramas. The most common one is to ignite gunpowder directly, resulting in instant high temperature and high temperature, and rapid carbonization of subcutaneous blood vessels to stop bleeding.

Of course, if it is like Sun Hao's current situation, it is not suitable. First of all, Sun Hao's wound is no longer bleeding, and secondly, Sun Hao's wound is festering and early symptoms of inflammation.

Now the most practical method is to use another method, first to remove the rotten and necrotic dead flesh of Sun Hao, and then use heart-burned charcoal, which is the simplest plant ash, to stop bleeding and sterilize the wound.

Although this method also has certain risks, it is also the most practical and safest method among all methods for the few people who do not have any antibiotics and anti-inflammatory drugs available on the isolated island.

Of course, the last step also needs to rinse the charcoal from the inside of the wound, and then keeping the wound dry can basically effectively avoid re-infection and inflammation of the wound.

After hearing what Yu Tina said, Ma Yongqiang thought for a while, and then grasped the most important point, clean and pure water. Now they even have a serious shortage of fresh water resources that can be consumed, let alone how much pure water they have to waste. The water went to wash away such a big wound to clean Sun Hao.
