Shifting Trends in Obstetrics: An 18-year Analysis of Low-risk Births at a German University Hospital.

Background/aim: At the beginning of the 21 century, obstetric medicine took a turn from interventional to restrictive in low-risk birth. The present study examined the changes in peripartum management over the past 20 years at the Women's University Hospital Cologne. The attitudes of the becoming mother and physicians towards anesthesia, episiotomy, and vaginal-operative deliveries were compared and the factors influencing the duration of birth over the past 20 years were examined.

Patients And Methods: In this retrospective study, the low-risk singleton birth of 955 in 2000/2001 and 944 births in 2018 at the Women's University Hospital Cologne were analyzed.

Results: The age of women who tended to give birth has significantly increased at present compared to 20 years ago. In 2018, labor was induced significantly more often than in 2000/2001. The rate of vaginal operative deliveries has fluctuated between 15% and 20% in the last 20 years. Forceps are no longer used. The use of episiotomy has taken a fundamental turn in the last 20 years. Prophylactic episiotomy is not performed anymore, most vaginal operative deliveries take place without the episiotomy. The birth duration has been significantly shortened at present compared to 20 years ago.

Conclusion: Pregnancy and childbirth over the last years are not considered as a disease, but as a natural course, and the trend of minimizing interventions in low-risk delivery has a positive effect on childbirth.
