kind
1, hydrogen peroxide is hydrogen peroxide, which has the function of disinfection and sterilization.
Precautions: ① The concentration is 3%, which is high and easy to burn the affected skin; (2) When it is used for superficial local wounds with certain infection, its blood, pus and so on. It will easily reduce its bactericidal power; ③ Unstable properties, short storage time and easy failure.
2. Boric acid water 3% Boric acid solution has cleaning, astringent and bacteriostatic effects, and is often used for washing and cleaning skin, mucous membranes and wounds, gargling stomatitis, acute eczema, acute exudative dermatitis and scalding wet compress.
Precautions: ① Don't use it widely and for a long time, and don't use it for babies or eyes; (2) Pay attention to the concentration, too high concentration will stimulate.
3, soapy water soapy water has a specific disinfection effect.
Precautions: ① The wounds bitten by dogs can be disinfected with 20% soapy water, which can neutralize, wash and inactivate rabies virus to a certain extent; ② After mosquito bites, washing with soapy water can relieve itching and local symptoms.
4, salt water only has the function of cleaning the wound, and has no disinfection effect.
Precautions: After washing, some commonly used external disinfectants, such as 2% iodine or 75% alcohol, should be applied to effectively sterilize and prevent wound infection.
Simple method for cleaning skin wounds: Add 1 g edible salt into 100 ml cold boiled water to prepare 1% physiological saline. If it can be washed with 0.9% physiological saline, it will be ideal. Because the concentration of saline is about 1% and the concentration of sodium chloride in human blood is the same, it will not stimulate the wound and will not cause human cells to rupture or shrink due to water loss.
Application mode
In every family's small medicine box, there are inevitably some commonly used disinfection drugs, such as iodine, mercury chloride, purple chloride, etc., which can be used in the case of bruises, cuts and burns. However, if it is not used symptomatically, there will be adverse reactions.
Mercury: Suitable for children. Mercury is suitable for superficial wounds such as skin abrasions and cuts. It is generally suitable for children with poor pain tolerance because of its weak irritation to wounds and no pain. But it can't be used with iodine, nor can it be used in the same place one after another. Purple potion: Purple potion can't be used to treat minor and small area burns and scalds, but it can't be used if the wound has suppurated and ruptured, otherwise a scab membrane will form on the wound surface, and pus in necrotic tissue will be difficult to discharge, which will aggravate infection.
Hydrogen peroxide: "bubble-free" ineffective hydrogen peroxide can also be used to clean and disinfect suppurative wounds. However, when hydrogen peroxide meets the secretion or pus of the wound, it will decompose free atomic oxygen and produce a large number of bubbles. Hydrogen peroxide is not easy to store. If there are no bubbles when cleaning the wound, the medicine has failed.
Iodine: Suitable for undamaged pustules.
Iodine has obvious bactericidal effect. Low concentration is generally used for skin disinfection, and more than 3% concentration can be used for inflammation such as folliculitis and paronychia, as well as undamaged pustules and boils. However, iodine is irritating, and broken wounds should not be used.
Contraindications for pregnant women
edit
Studies have shown that chemical pollution caused by household detergents is harmful to human health, especially when it is not used properly. For example, when toilet cleaner is mixed with disinfectant, the chlorine content in toilet cleaner is very high. When combined with ammonia-containing detergent, chlorine gas will be produced, which will irritate the eyes, nose, throat and even damage the lungs. When spray disinfectants and cleaners are mixed with deodorants and air fresheners, they will also produce chemical reactions harmful to human health, especially to pregnant women and fetuses.
Correction method:
* Avoid direct contact of pregnant women with detergents.
* Do not mix detergents and disinfectants. Bathroom washing, toilet cleaning and kitchen washing products must be used separately.
Carcinogenic cause
edit
Improper use of various household hygiene products may cause cancer. For example, many families like to put disinfection water and other cleaning products, often in the corner of the room or bathroom. In fact, after they evaporate, they often accumulate a lot of harmful gases. Especially when taking a bath with hot water in the bathroom, the evaporation of disinfection water is more toxic.
Some disinfected water also contains dichlorobenzene, which will stimulate the respiratory tract, mutate cells and induce leukemia and lung cancer. So don't put disinfectant in the corner or bathroom. It is suitable to put it on a well-ventilated drying table, and it is best to seal it.
As for families who love deodorant, if they want to keep the air fresh, they can often open the window or use an exhaust fan. Deodorant is a chemical compound after all, and it may also induce cancer.
