Shoulder dystocia: An evidence-based evaluation of the obstetric nightmare

The recent emphasis on evidence-based medicine has shattered many of the myths and misconceptions surrounding shoulder dystocia.

This stems from the fact that there are many unresolved issues surrounding its occurrence, including such variables as prediction and prevention as well as the estimation of fetal birth-weight. Only through the accumulation and application of scientific information relating to the multiple antepartum and intrapartum aspects of shoulder dystocia will the obstetrician ultimately be able to deal with this "obstetric nightmare".
