| Outline of Final Research Achievements |
This research was conducted with the goal of verifying the effectiveness of breastfeeding guidance and care using ultrasonography (US),
Study 1) Collected US imaging data from mid-pregnancy to one month postpartum to clarify images in physiological changes. It was shown that dilation of the milk ducts and thickening of the mammary gland were observed with the course of pregnancy. Although dilation of the milk ducts just below the nipple can be depicted in the breast engorgement around 3 days postpartum, it becomes difficult to depict the milk ducts in the entire breast. In study 2, US imaging data were collected and analyzed before and after care of cases with granulomatous mastitis and mastitis symptoms. Study 3) showed the convenience of pocket echo in midwifery implementation, and although the technique was learned quickly, the difficulty of reading images was an issue. Education on how to view and interpret images is especially needed for implementation in clinical practice.

| Academic Significance and Societal Importance of the Research Achievements |
母乳育児は、母親の乳がん卵巣がんなどの発症リスク軽減し、児の感染症の予防などの影響が明らかにされている。しかし、日本の母乳育児率は６０％に届かず母乳育児の継続率の向上が課題とされている。今回、超音波診断装置（US）を用いて、乳房の生理的変化やケアの影響を可視化することができ、その有用性と課題を示すことができた。今後は、USを用いた母乳育児支援の臨床への適応と母乳育児率への効果を検証する研究が必要であり、本研究は、母乳育児率及び継続率の向上のための研究の発展に寄与した。
