[Update in Obstetric Anesthesia - Tried and Trusted Methods, Controversies and New Perspectives].

Since 1975, a plethora of lectures within the context of annual meetings relevant for the clinical care has been summarized in "what's new in obstetric anesthesia" by the society for Obstetric anesthesia and Perinatology which can be recommended to everyone interested in anaesthesiology in the delivery room. After the death of Gerard W. Ostheimer, Professor of Anaesthesiology at Brigham and Women's Hospital in Boston, Massachusetts, it became renamed the Gerard W. Ostheimer "what's new in obstetric anesthesia" lecture to honor his contributions to regional anesthesia and obstetric anaesthesia. Each year the event held by selected professional representatives and their imprint in leading anesthesia journals give insight into a critical appraisal of recent literature and the possible consequences for - but not only - the anaesthetic delivery room practice.A similar event has been established in Germany for more than 16 years (first event on April 1, 2000, most recently held on February 27, 2016, in Munich): the obstetrical anesthesia symposium of the academic working group "regional anesthesia and obstetrical anesthesia" [1], [2]."Evergreens" or "hot topics" with regard to anaesthesiological delivery room practice are presented and discussed regularly. The lectures often reveal the subtle change of the issues being debated much earlier than traditional textbook chapters do. This manuscript summarizes important findings from the last symposium held in 2016. Part I focuses on relevant causes for maternal morbidity and mortality as well as preventive measures, pregnancy in obese patients and sepsis in obstetric anaesthesia. Part II addresses established standards and new perspectives in the direct obstetric setting regarding epidural analgesia, post-dural puncture headache, anaesthesia and analgesia during and after caesarean section, haemodynamic monitoring during cesarean section and postpartum haemorrhage.
