Clinical efficacy of Gualou Xiaoyong Decoction and painless lactation manipulation in treating lactation acute mastitis and breast abscess: An observational study.

Information on the effects of Chinese medicine in the treatment of lactational acute mastitis and breast abscess is limited; thus, we conducted an observational study to analyze the clinical efficacy of Gualou Xiaoyong Decoction combined with painless lactation manipulation in the treatment of lactational acute mastitis and breast abscess. A total of 41 patients with lactational acute mastitis and breast abscess who were treated with Gualou Xiaoyong Decoction and painless lactation manipulation from October 2021 to October 2022 were included in this study. The age, fetal times(primiparous/multiparous), delivery mode (cesarean section/vaginal delivery), onset time, breast lump diameter, skin rash diameter, body temperature, visual analogue score, blood routine, C-reactive protein, procalcitonin, bacterial culture in milk, B ultrasound and other data of these patients were statistically analyzed. After treatment, the breast lump diameter of these patients decreased significantly, the skin rash diameter was reduced or disappeared, the body temperature decreased or returned to a normal range, and the visual analogue score also decreased. Besides, these patients had a decreased total number of white blood cells and a reduced percentage of neutrophils, C-reactive protein, and procalcitonin after treatment. In addition, bacteria in the milk of most patients disappeared, and there was no abnormality in B ultrasonic imaging. Except for 2 patients with breast abscess who stopped breastfeeding on the affected side for 1 day and 3 days respectively, all other patients continued to provide breast milk for their infants, and no adverse reactions were observed in these infants. The combination of Gualou Xiaoyong Decoction and painless lactation manipulation can achieve favorable clinical effects in the treatment of lactational acute mastitis and breast abscess. This combined therapy has good efficacy, short course of treatment, low costs, and great convenience with the avoidance of pain, hospitalization, influence on lactation, breast scar and other adverse outcomes.
