Acute septic mastitis often occurs during lactation, especially within 1 to 2 months after the birth of a primiparous woman, so it is also called acute lactation or puerperal septic mastitis, which in Chinese medicine becomes “canker sores”. The incidence of acute mastitis in primiparous mothers is as high as 2% to 4%, which is one times more than that of mastitis in menstruating mothers. The onset of milk stagnation with bacterial infection is acute inflammation with redness, clock, heat, pain, chills, and high fever. In the early stage, breast milk can be drained by manipulation and herbal treatment, but after septicemia, it needs to be drained by incision. The actual mastitis can be prevented by preventing it from the second trimester of pregnancy and by taking care of it during the puerperium. The actual mastitis is a very good thing. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. The use of heat and detoxification, liver detoxification, with the use of traditional Chinese medicine with the technique of breast drainage more than 1 week to dissipate, commonly used gua atrophy, Gong Ying, leak reed, Shanjia, mother of pearl, deer horn cream, low fever with Chai Hu, high fever plus raw gypsum, constipation plus burdock, milk plus raw malt 120g to reduce milk secretion. Because of the postpartum deficiency, it is forbidden to use too much bitter-cold, and it is not advisable to use Di Ding, Lian Qiao and Da Huang. Breastfeeding can be continued during medication or with the healthy side alone. If high fever can be combined with infusion, penicillin, cephalosporin antibiotics can be. Note that it is not advisable to use a large amount of antibiotics too early. Excessive or prolonged use of antibiotics is the same as the result of too much bitter cold in Chinese medicine, that is, the lumps are difficult to disappear and easily turn into chronic. During the use of antibiotics, it is recommended not to breastfeed. When acute mastitis reaches the stage of abscess formation, it requires prompt incision and drainage. The size and location of the incision is based on the principle of ensuring that the pus comes out unobstructed. Because breast abscesses are often multi-housed, it is necessary to separate the connective tissue intervals of multiple pus cavities with the fingers in order for drainage to be unobstructed. For abscesses deep in the breast, high fever and chills are the main manifestations, and local redness and swelling are unknown farts, not to mention the sense of fluctuation. A puncture and pus aspiration test can be done first to confirm the presence of pus before making an incision. It is best not to wait for a breast abscess to break down on its own, because the pus cavity is often multiple or one after another, and a self-ruptured breach cannot be thoroughly drained. Generally speaking, as long as the pus comes out clean and the fever subsides, purulent mastitis enters the wound healing period and the dressing is changed every other day and the wound heals within one month.
