  • Objectives: The definition of Sanhupung (Puerperal wind disorder) has been varied and there has been a prior study to establish the definition, but no clear conclusion has been reached on diagnostic criteria. Therefore, the aim of this study was to clearly redefine the definition of Sanhupung using the Delphi method. Methods: This study used the Delphi technique. A panel consisting of 13 experts of Korean medicine, particularly in Obstetrics & Gynecology, participated in the Delphi survey that included answering the 3rd round survey. The Delphi survey was conducted by evaluating and correcting the questionnaire using e-mail. Results: Through the Delphi survey, we have reached an agreement regarding the diagnostic criteria of Sanhupung. They are as follows: 1) Sanhupung can be diagnosed based on basic symptoms. If one or more symptoms are expressed in the basic symptom group, it can be diagnosed as Sanhupung. It is diagnosed in detail as a pain type or a sensory impairment type according to the category of basic symptoms. 2) Incidental symptoms are not essential for diagnosis, and are referred to for checking general weakness and autonomic nervous system conditions. 3) In order to meet the diagnostic criteria, the symptoms should occur within 6 months after childbirth or miscarriage, and the cause of the symptoms should not be classified as other diseases. Conclusions: The diagnostic criteria of Sanhupung were suggested based on the Delphi survey among experts in the field. Further research is necessary to improve the reliability and validity of the criteria.
