Recently, I admitted a lactating mother with breast abscess, who had previously practiced breast augmentation with Omegadine injection for more than 10 years. The right breast was rapidly enlarged after 3 days without obvious cause, the same incision and drainage, a total of 1200ml of the above fluid, and then bilateral residual cyst wall scraping after healing, the clearance rate of Omedine reached 99.9%, the course of the disease was extended nearly 2 months. So, what are the complications of Omnidene injectable breast augmentation and the harm to maternity and infants? Olmedin, the scientific name of polyacrylamide hydrogel, is a colorless and transparent jelly-like liquid substance. It was introduced into China in the 1990s as a non-toxic, environmentally friendly, low rejection new artificial fat, from simple rhinoplasty, temple augmentation, to larger breast augmentation, buttock augmentation and various soft tissue depression filling have been used, in China, about 300,000 women have received Omnidene injectable breast augmentation. Omnidene is a composite material, which is non-toxic to human body, but after injected into human body, it will be decomposed to produce highly toxic. Because of its ability to decompose into highly toxic monomer molecules in the body, poisoning the nervous system, damaging the kidneys and causing harm to the life circulation system, the World Health Organization has listed this substance as one of the suspected carcinogens, which is a time bomb of danger. For the local breast, it can cause breast inflammation, infection, breast deformation, displacement, etc. Long-term stimulation can also cause cancer. During pregnancy and lactation, the degraded Omnidene monomer will not only be potentially harmful to the mother, but its toxicity will also affect the health of the fetus and baby, and serious nerve damage or even fatal. During pregnancy and breastfeeding, patients with Omnidene injectable breast implants have decreased body resistance, distended milk, and are prone to infection and rapid formation of abscesses. The anesthetic drugs used in surgical treatment and the antibiotics applied after surgery may cause fetal malformation. When breastfeeding, the monomer decomposed in the human body can pass through the milk ducts and secrete to the nipple with the milk, which can make the milk yellow and be sucked by the nursing baby and enter the baby’s body, causing harm to the baby’s kidney, cardiovascular system and nervous system. There have been cases where the infant suffered neurological damage and became a “vegetable” as a result of feeding this kind of milk. Therefore, we suggest that patients with injectable breast augmentation should be removed as soon as possible, regardless of whether there are complications or not, and that women who are preparing for pregnancy should undergo removal surgery at least half a year in advance to minimize the impact of Omniderm on themselves and their offspring.
