Shoulder dystocia

Shoulder dystocia is an obstetric urgency which requires a fast and effective handling. Resulting brachial plexus lesions, hypox states and deceases derived from a shoulder dystocia are often the subject of forensic medicine disputes contexting the Obstetrician doesn't perform the caesarean section. Brachial plexus lesions mechanism is directly correlated with untimely and excessive traction performed to resolve a shoulder dystocia.These tractions lower the thorax towards the pelvis and thus the thoracic cone while descending, it increases the bisacromial diameter. Neonatal morbidity is represented by Erb's palsy, phrenic nerve palsy and a consequence diaphragm palsy, and finally by fractures of the clavicle. Recent medical literature describes shoulder dystocia rate is between 0,5% and 1,5% of deliveries. Risk Factors Shoulder dystocia most important risk factor is fetal macrosomia. Diabetes is an important twofold risk factor. Here are further factors; operative vaginal delivery; previous shoulder dystocia; advanced maternal age.

Internal maneuvers have to be performed if a failure occurs. Woods is one of the first maneuvers to be performed. Rubin maneuver consists of the opposite kind of move. One of the most classic maneuvers is the Jacquemier maneuver: it's based on the extraction of the posterior arm. If all these maneuvers fail only two alternative possibilities remain. Zarate maneuver and Zavanelli maneuver.
