As we all know, infertility patients spend a lot of energy and financial resources in the process of assisted conception, coupled with the special characteristics of assisted conception and pregnancy, the originally common “common cold” will also make the patient trembling with fear, as if the enemy, worrying that the cold will affect the artificial insemination or reduce the success rate of IVF, and even affect the development of the fetus. Below I will lead you to approach the common cold, unveil the cold, clarify the cause of the cold and its impact on the fetus and the specific ways to deal with prevention and treatment. The common cold is medically known as an upper respiratory tract infection, referred to as the upper sense, is a general term that includes acute inflammation of the nasal cavity, pharynx or larynx. The broad sense of the upper sense is not a disease diagnosis, but a group of diseases, including the common cold, viral pharyngitis, laryngitis, herpes pharyngitis, pharyngoconjunctival fever, bacterial pharyngo-tonsillitis. Narrowly defined, epiglottitis, also known as the common cold, is the most common acute respiratory infectious disease, mostly self-limiting, but with a high incidence. It occurs two to four times a year in adults and more frequently in children, six to eight times a year. It can occur throughout the year, but is more common in winter and spring. It is still unclear how the common cold affects the fetus. Generally speaking, colds in the early stages of pregnancy have a relatively greater impact on the fetus. Because this is a critical period for the development of fetal organs, bacteria, influenza viruses, or cold medications may cause fetal malformations such as congenital heart disease, as well as cleft lip, hydrocephalus, anencephaly, and microcephaly, and in severe cases, termination of pregnancy may be recommended. The effect of colds on the fetus in the middle and late stages of pregnancy is relatively minor because the organs of the fetus are basically formed during this period and rarely cause adverse effects. However, if a severe cold occurs during this period, a prolonged high fever can hamper the development of the fetus in the womb, and in the case of late pregnancy, extreme coughing can cause early water breakage or even preterm labor. The common cold is a self-limiting illness, and the purpose of medication is only to relieve the symptoms and prevent complications from occurring and developing. Like any other patient, a cold will usually clear up on its own during assisted conception or pregnancy. If it is only a mild cold, that is, the cold symptoms are mild, mainly manifested as sneezing, nasal congestion, no fever, consider that there is a certain relationship with the weather change cold, no need to take medication, you can take non-pharmacological therapies, that is, strengthen the exercise, pay attention to the ventilation of the living room, drink plenty of boiled water, a light diet, eat more vegetables and fruits, to maintain a smooth bowel movement, and pay attention to rest, warmth, with oral multivitamins tablets, and avoid going to public places, generally within a week can be cured by itself. Generally, it can be cured within one week, and can continue to perform artificial fertilization, egg retrieval, transplantation and other surgeries. If the cold symptoms are more serious, especially coughing, coughing up sputum, obvious fever (body temperature over 38 degrees) and other symptoms, you should consult the doctor in time, blood tests and C-reactive protein to rule out bacterial infections, such as white blood cells and neutrophils are high, generally considered to be bacterial infections, oral penicillin or cephalosporin drugs with traditional Chinese medicine Shuanghuanglian or Xiao Chaihu and other medicines to reduce the fever is relatively safe, more than three days without significant improvement of symptoms need to be further to a higher level of consultation and treatment. If there is no significant improvement in symptoms after 3 days, it is necessary to go to a higher level hospital for further consultation and treatment. If the cold symptoms are severe but there is no obvious evidence of bacterial infection, it is generally considered to be a viral cold, and relatively safe proprietary Chinese medicines can be used for symptomatic supportive treatment, such as Banlangen Chongtian, Pu Dilan Oral Liquid, Shuanghuanglian Oral Liquid, or Chaihu Granules. Severe colds, such as temperature higher than 38 degrees after general treatment of the body temperature back to normal, does not affect the artificial insemination or egg retrieval and transplantation, the temperature continues to be high, it is recommended to give up artificial insemination surgery, or egg retrieval after the embryo frozen, the next time thawed and transplanted. If the man has a cold, the woman must take good isolation measures to avoid cross infection. If the body temperature is lower than 38 degrees, drink more water, rest, can be normal sperm retrieval, artificial insemination or IVF embryo transfer; if the body temperature is higher than 38 degrees, you need to take the relatively safe cold medicine mentioned in this article, get better and then retrieve the sperm normally, or else it is recommended to cancel the current cycle of assisted conception. To summarize, for the common cold, the majority of infertility patients in the critical period of fertilization or pregnancy to be aware of, easy to cope with, in order to prevent talk about the color of the cold, so that we work together, to fulfill your beautiful dream of conceiving a healthy baby!
