According to expert analysis, there are three channels for mother-to-child transmission of AIDS: intrauterine transmission, childbirth and breastfeeding. Therefore, the effective blocking methods are prenatal medication, cesarean section and postpartum stop breastfeeding and switch to artificial feeding. Among the three modes of transmission: intrauterine transmission, childbirth and breastfeeding, the probability of transmission through childbirth is the highest, accounting for 70%-80%.
? However, it is entirely possible for pregnant women with AIDS to give birth to healthy babies as long as they take antiviral drugs according to the doctor's advice and implement mother-to-child blocking? Associate Professor Li believes that mother-to-child blocking is a problem faced by pregnant women infected with AIDS. During pregnancy, during childbirth, after childbirth? Take antiviral drugs according to the doctor's advice in the three stages, especially after delivery, you need to take medicine to your baby in time, and you can't breastfeed. You should test every three months until 18 months. If it is positive, we should implement comprehensive AIDS treatment like adults. If the results meet the standards of blocking mother-to-child transmission of AIDS formulated by China CDC and UNICEF, it means that the whole blocking treatment has been effectively completed and the baby has become a healthy baby.
Experts also suggest that it is not recommended for pregnant women with AIDS to give birth naturally, because it takes a long time to give birth naturally, and squeezing the birth canal will also increase the risk of mother-to-child contact. It is recommended that pregnant women with AIDS have transmission interruption and caesarean section.
Experts pointed out that the majority of women of childbearing age must master health care knowledge, establish healthy sexual concepts, and curb female infection and mother-to-child transmission from the source. At the same time, women of childbearing age are called for premarital examination and pregnancy examination. If it is found to be positive, it is necessary to immediately go to the infectious disease hospital to implement mother-to-child blocking, and keep the child away from contact with the mother's blood and body fluids after giving birth, but it is generally ok to hug and touch.
Factors affecting mother-to-child transmission ① Maternal infection with HIV: Women with high viral load are more likely to transmit HIV to their children than women with low viral load.
② Obstetric factors: The longer the labor process, the greater the risk of infection; When twins are born, the risk of infection in the first child is greater than that in the second child; The infection rate of vaginal delivery is higher than that of cesarean section.
③ Nutritional factors: nutritional deficiency can affect the integrity of mucosa, promote the discharge of HIV in cervix and vagina, and increase vertical transmission.
④ Combined infection with sexually transmitted diseases: The transmission rate of mothers with combined infection is higher than that of mothers with single infection.
⑤ Breastfeeding: Mothers have the highest risk of transmission through milk after delivery.
⑥ Premature infants and low birth weight infants: Infants born to infected mothers have low weight, and infants born before 34 weeks are more susceptible to infection than those born after 34 weeks.
