The project aims to find a relationship between the positioning of the foetus before and during birth and the results of obstetrics and to determine their incidence in the Polish population. The study will be conducted by combining the use of ultrasound diagnostics, midwives observations during childbirth, analysis of medical documentation and a questionnaire on the activity of examined women. The obtained results will be used to prepare guidelines for the birth in a particular foetus position.

The purpose of the examination is to describe the difficulties associated with delivery in a non-optimal position of the fetus. Initial observations show that such childbirth is perceived as difficult by both the women giving birth and the staff. The aim of the study is to describe the level of difficulty of this labor, expressed as the experience of the woman, as well as all the elements that may affect the difficulty of this labor, for example, slower or no progress in labor, disturbances in systolic function, injuries, the need to use epidural anesthesia, increased blood loss.
