[Clinical aspects of the preparation, performance, and follow-up of a first trimester abortion].

In January 2023, the "S2k guideline on abortion in the first trimester" of the Association of Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.", AWMF) was published, which was commissioned by the Federal Ministry of Health ("Bundesministerium für Gesundheit", BMG). The guideline deals with surgical and medical abortion after counseling, with criminological or medical indication in the first 14 weeks of pregnancy, based to the last menstrual period. In this review article, based on this guideline, the procedures for medical and surgical abortion are compared as well as the advantages and disadvantages of the two methods. Clinical and practical aspects of preparation and implementation, complication management, and immediate aftercare for abortion are presented.
