Under the new crown epidemic, home disinfection has become a must-have job for families. However, there are some disinfection methods that are not suitable for pregnant women, and we should pay more attention.
1. Peroxide-based disinfectants
Peracetic acid is a representative substance of peroxide-based disinfectants. During the SARS epidemic in 2003, as the main force for disinfection in public places, it has super oxidative properties, thus playing the effect of sterilization and disinfection. However, such disinfectants are unstable, highly corrosive and irritating. Long-term use will cause damage to the eyes and respiratory mucous membranes, so it is generally not recommended.
2. Chlorine-containing disinfectant
Chlorine-containing disinfectant has no obvious effect on the development of embryos, so there is no need to worry too much, but try to avoid contact with high-concentration chlorine-containing disinfectants, as it will stimulate the respiratory tract and mucous membranes. When using it, the higher the concentration, the better. If you need to use it, you must read the instructions carefully, strictly check the proportioning concentration, and take relevant protective measures, such as wearing rubber gloves and wearing masks. Among them, the 84 disinfectant itself is relatively corrosive and has a pungent odor. Pregnant mothers should be careful not to directly contact disinfectants, and do not use such disinfectants too frequently.
3. Chlorhexidine
Hand sanitizers containing chlorhexidine should be avoided. Chlorhexidine is a cationic surfactant, which has a strong bactericidal effect and cannot effectively inactivate viruses, so it is not suitable for hand disinfection during the new coronavirus epidemic.
4. White vinegar and white wine
Although white vinegar can kill some germs, there is no firm conclusion on whether it is effective against viruses. In addition, the use of liquor instead of alcohol cannot exert a disinfection effect, because the alcohol concentration of liquor cannot reach the disinfection concentration.Therefore, it is not recommended to use white vinegar and white wine instead of disinfectant.
5. Alcohol
Pregnant women who are allergic to alcohol are not suitable for alcohol disinfection. Alcohol can be used for surface disinfection. Do not spray alcohol in the air, because the concentration of alcohol in the air is too high, which may cause a fire risk. Studies have shown that the disinfection effect of alcohol is not the higher the concentration, the better the effect. 75% alcohol has the best disinfection effect, while 95% alcohol cannot be used as a disinfectant. Because the alcohol concentration is too high, a solidified film will soon be formed on the surface of the microorganism, preventing the alcohol from infiltrating into the interior, and it is difficult to play a disinfection effect. If the alcohol concentration is too low, the ability to denature proteins is weak, and it is not easy to kill the disease.
6. Problems that should be paid attention to when applying other disinfection methods.
Pregnant women should always open windows for ventilation when they are at home. At present, it has been confirmed that ultraviolet lamps have an effective disinfection effect and can be used for air and clothing disinfection. All purchased items can be disinfected with ultraviolet lamps, but ultraviolet rays have a serious burn effect on the cornea, so cover and protect your eyes when using them. When using disinfectant, disinfectant paper towels, 75% alcohol and other items for disinfection, skin protection must be done to prevent skin damage and allergies.
