Pregnant women can use iodine to disinfect. Iodine, also known as tincture of iodine, is a commonly used topical disinfectant at home, with a strong effect of killing bacteria and mold and killing bud cells, and can be used to treat wounds to avoid infection, septicemia, fever and other undesirable symptoms, but several points need to be noted: 1. Disinfection site: Iodine is suitable for the skin of the extremities and trunk, and should not be used around the eyes, mouth, nose and perineum, and should not be taken orally; 2. Disinfection area and time. Iodine should not be used for too large an area or for too long a time, otherwise it will absorb some of the iodine and alcohol and affect the fetus. If the use of iodine for 3 consecutive days has no effect, you should consult a doctor at a hospital; 3. Wound conditions: Iodine is used for disinfection of minor skin wounds and is generally not suitable for skin where ulcers occur; 4. Drug properties: Iodine left for too long will undergo a series of reactions, resulting in free iodine content The decrease in bactericidal power and the increase in irritant products will enhance the irritation of the skin, so it is not advisable to use iodine that has been stored for too long. If burning sensation, itching, redness or swelling occurs at the site of application, the drug should be stopped immediately, and the local drug should be washed off and, if necessary, medical attention should be sought. Routine skin disinfection is recommended with iodophor. The solvent of iodine is alcohol, while the solvent of iodophor is water, which is much less irritating and does not cause significant pain compared to iodine.
