This paper analyzed the legal issues existing on the medical side in 20 medical damage cases in obstetrics from January 2020 to June 2022 in China Judgment Documents Network， and hoped to explore the paths that the medical side can use for reference in building a harmonious doctor-patient relationship in the legal context. Firstly， medical institutions should establish rescue evaluation systems and early warning mechanisms for critical pregnancy and maternal， so as to ensure the health and safety of life of pregnant women and newborns， as well as prevent the occurrence of adverse obstetric events. Secondly， strengthening the cultivation of the humanistic quality among obstetric medical practitioners is the basis of the harmonious obstetrical doctor-patient relationship. Thirdly， the training and learning of relevant laws and regulations such as the Civil Code of the People’s Republic of China and the Physician Law of the People’s Republic of China should be strengthened. Fourthly， the patients’ informed consent should be respected， the process and procedures of fulfilling informed consent should be standardized by the systems， and the forms for fulfilling informed consent should be further explored. Fifthly， the medical risk-sharing mechanism should be explored and this paper suggested that postpartum women purchase obstetric accident insurance to reasonably share medical risks. Sixthly， medical social workers should be introduced， doctor-patient communication should be strengthened， and the obstetric risk awareness of the whole society should be enhanced.
