Shoulder dystocia: an Evidence-Based approach.

Shoulder Dystocia (SD) is the nightmare of obstetricians. Despite its low incidence, SD still represents a huge risk of morbidity for both the mother and fetus. Even though several studies showed the existence of both major and minor risk factors that may complicate a delivery, SD remains an unpreventable and unpredictable obstetric emergency. When it occurs, SD is difficult to manage due to the fact that there are not univocal algorithms for its management.Nevertheless, even if it is appropriately managed, SD is one of the most litigated cause in obstetrics, because it is frequently associated with permanent birth-related injuries and mother complications.All the physicians should be prepared to manage this obstetric emergency by attending periodic training, even if SD is difficult to teach for its rare occurrence and because in clinical practice it is often handled by experienced obstetricians.THE PURPOSE OF THIS STUDY IS TO REVIEW THE LITERATURE CONCERNING THE EVERLASTING PROBLEMS OF SD: identification of risk factors for the early detection of delivery at high risk of SD and a systematic management of this terrifying obstetric emergency in order to avoid the subsequent health, medico-legal and economic complications.
