Continuous breastfeeding during breastfeeding is necessary to promote recovery. General management consists of frequent emptying of the breast, rest, cold compresses after breastfeeding, and antibiotics if necessary. If the condition does not improve after 24 h of conservative treatment and is accompanied by persistent fever, headache or flu symptoms, a specialist medical examination should be performed and medication should be applied. As the name implies, mastitis is an inflammation of the breast tissue, but mastitis does not necessarily mean infection. Mastitis during breastfeeding is characterized by swollen, tender, red breasts as well as pain. It is usually difficult to determine whether the inflammation is caused by swelling or by blocked milk ducts. Continued breastfeeding is necessary at this time to promote recovery. General management consists of frequent emptying of the breast, rest, cold compresses after breastfeeding, and antibiotics if necessary. If the condition does not improve after 24 h of conservative treatment and is accompanied by persistent fever, headache or flu symptoms, a specialist medical examination should be performed and medication applied. Continuing breastfeeding is the best way to prevent and treat breast swelling, mastitis and breast infections; stopping breastfeeding will increase the chance of breast infections turning into breast abscesses. I. The reason for breast swelling In 2 to 4 d after delivery, colostrum gradually turns into mature milk called the second stage of lactation, because there is more blood, lymphatic tissue, breast milk flow to the breast, so that the mother feels heavy and full breast, which belongs to physiological breast swelling, as long as the baby sucks the breast correctly can suck out the breast milk, so that the breast swelling is relieved. If the mother does not breastfeed for 10 to 14 days and does not express the milk in time, the breast will soon become swollen, swollen and painful, and the nipple will be flattened due to swelling, so that the baby will not be able to take the breast smoothly, resulting in the tissue in the breast being compressed and the milk accumulating and forming abnormal breast swelling. Reasons for breast swelling: late start of breastfeeding after birth; incorrect posture of the baby’s breast; not breastfeeding on demand or not squeezing out the milk in time when the mother and baby are separated; restriction of breastfeeding time and inability to empty the breast. Care for swollen breasts 1. Apply hot compresses before breastfeeding to assist the flow of breast milk. 2.Place raw cabbage leaves on the breast under refrigeration or at room temperature for 20 to 30 min/time until the swelling is relieved. 3.Ice packs on the breasts can reduce the degree of swelling and slow down the production of milk. 4. During breastfeeding, pay attention to the breastfeeding posture, correct any problems and adjust the breastfeeding posture in time. 5. Try to keep the baby’s chin facing the position of the lump when sucking. 3. Breast massage and manual milking methods In case of breast swelling, we can also use manual milking methods to relieve breast swelling. Steps: apply hot compresses to breasts or drink hot drinks to stimulate the lactation reflex; massage breasts; manual milking. Massage the breasts from the outside of the breasts in the direction of the milk ducts towards the nipples. Massage 1 circle with moderate intensity for 5 to 10 min. After massage, perform milking by placing the thumb and index finger at the areola and pressing down gently in the direction of the chest wall, changing the position of the thumb and index finger around the areola continuously to empty the milk. IV. Handling of mastitis If the swelling of the breast is not relieved in time and the milk does not flow smoothly, the milk will become sticky and block the milk ducts, which will easily cause mastitis. Is it possible to breastfeed after mastitis? The answer is yes. After mastitis, mothers should be instructed to continue to feed frequently because mastitis is an inflammation of the tissues surrounding the breast and will not affect the milk secreted by the milk follicles, so they can continue to breastfeed. Frequent sucking by the baby can help the mother to reduce the discomfort caused by mastitis and promote the improvement of mastitis.
