The causes of mastitis are firstly bacterial invasion and secondly the accumulation of milk. The accumulation of milk mainly occurs during breastfeeding, due to the position of holding the child or unintentional bumps by the child, which cause damage to the milk ducts, constriction of the ducts, leading to a large amount of milk being trapped inside the ducts. Since milk is an excellent culture medium, it results in bacterial growth. Bacterial invasion usually occurs through cracked or fissured nipples, allowing bacteria to enter the milk ducts and into the breast tissue, causing mastitis. Another situation is a decrease in the body's immune system, for example, due to poor sleep or emotional stress. These are the main causes of acute mastitis.

What should be noted for acute mastitis?

For acute mastitis, it is important to keep the nipples clean. The nipples should often be washed with soapy warm water, and rinsed with clean water before and after breastfeeding. Patients with inverted nipples should gently extrude the nipple before cleaning it, but should not use alcohol to clean the area, as alcohol can make the skin of the nipple and areola brittle and prone to cracking. It is important to develop good breastfeeding habits, breastfeeding on a regular schedule, and ensuring that all the milk is drawn out each time. If the milk cannot be fully expressed, it should be manually massaged out or extracted using a breast pump. Additionally, do not let the baby sleep with the nipple in their mouth. If there are any nipple injuries or cracks, stop breastfeeding, use a breast pump to extract the milk, and resume breastfeeding only after the wounds have healed.

Acute mastitis occurs how long after childbirth?

Acute mastitis can occur a few weeks after childbirth, usually within the first two to three weeks, although it can also appear later during the breastfeeding period. The key issue is to maintain the flow of breast milk and the patency of the milk ducts during breastfeeding. It is recommended to wash both nipples before breastfeeding, let the baby completely empty one breast first, then move on to the second breast. If the baby is full and doesn't finish the milk from the other breast, it's best to empty that breast either by using a breast pump or having the father extract the milk. For the next feeding, start with the other breast, which was the second breast previously used, and alternate accordingly. Additionally, nipple care is important; after the baby has finished feeding, express a little milk and apply it on the nipple surface. Before the next feeding, wash the nipple with clean water more diligently. This can help reduce the occurrence of acute mastitis.

Early treatment of acute mastitis

In the early stages of mastitis where there is pain but no redness and swelling, applying heat and then having a lactation masseur clear any residual milk can be effective. However, if symptoms like high fever and chills occur, along with localized redness and swelling, it is advised to go to the hospital to have a complete blood count and an ultrasound. If the leukocyte count is under 10,000 and there is localized swelling, topical application of Rifanuo and oral anti-inflammatory medication can be curative, but it is necessary to stop breastfeeding. If the leukocyte count exceeds 10,000, intravenous antibiotics may be required, alongside cessation of breastfeeding. Then, using a breast pump to extract the milk can help in healing. (Please use medications under the guidance of a doctor.)

Is hot compress effective for acute mastitis?

An important factor in acute mastitis is the accumulation of milk during breastfeeding, which leads to mastitis. Applying heat can be somewhat effective, as it helps to unblock the milk, thus further alleviating and controlling the symptoms of mastitis. However, heat application is mainly used in the initial stage of mastitis. If the condition progresses further, with more apparent systemic symptoms or pus formation, then heat application is not very effective. Further anti-infection treatment and, if necessary, incision and drainage surgery are needed to control the condition.

Acute Mastitis Symptoms and Treatment

Patients with mastitis often feel pain in the breast, with localized redness, swelling, and fever. As the inflammation progresses, there can be chills, high fever, and increased pulse rate, often accompanied by swelling and tenderness of the lymph nodes on the affected side. A routine blood test can show a significant increase in white blood cells. For treatment, if there is swelling, it is recommended to stop breastfeeding and apply topical Levofloxacin. Blood tests should be checked, and if white blood cell count exceeds 10,000, intravenous antibiotics are advised. If below 10,000, oral anti-inflammatory drugs can be taken for symptomatic treatment. After three days, recheck the blood routine to decide on further symptomatic treatment.
