Ye’s mother, who had just been discharged from the hospital, looked at her three-month-old baby and regretted her rash decision, which resulted in her baby not being able to breastfeed. Half a month ago, a hard lump appeared in Ye’s left breast, accompanied by obvious redness and swelling, and she heard that a lactationist could eliminate the hard lump through massage. After two massages by a lactation therapist, the lump was not only not eliminated, but the redness and swelling increased and the fever continued unabated. Her family rushed her to Wuhan Sixth Hospital (affiliated with Jianghan University), where she was seen by Dr. Li Rong, deputy chief of the Department of Mammary Surgery, and was diagnosed with acute suppurative mastitis and breast abscess in the left breast. On the day of admission, emergency surgery was performed to cut and drain, and although he recovered and was discharged a week after surgery, his baby never had the chance to eat breast milk again. Director Li told reporters: acute mastitis is due to breast lumps and blocked milk ducts, while the nipple has a hidden fissure bacterial invasion occurs, this time you need to unblock the milk ducts, but should not over squeeze massage breast. If the lactation practitioner does not do it correctly, massage improperly and with too much force, it often leads to the spread of infection. Mama Ye had a high fever of 40°C at the time of her visit, and her large half of the breast was red and swollen with unbearable pain. Emergency surgery was performed to drain about 200 ml of pus, and the abscess spread all the way to the posterior space of the breast. Breastfeeding mothers also need to be cautious about hiring a lactationist, a profession that currently lacks special training standards and is not nationally recognized. And mastitis can sometimes cause very serious harm if not treated in a timely manner or improperly treated. One such patient, in more serious cases, can also develop septic sepsis, which can be life-threatening. When breastfeeding symptoms such as hard knots, pain and fever in the breast are present, it is advisable to choose a breast specialist at a regular professional hospital to receive guidance and treatment. Mastitis during breastfeeding is a preventable disease and young mothers need to be actively educated about breastfeeding when they are pregnant, learning about breast nipple preparation before breastfeeding, the correct way to breastfeed, and techniques to express breast milk. Avoid mastitis and let your baby grow up healthy with your mother’s milk.
