Perinatal outcome and the type and number of maneuvers in shoulder dystocia.
To ascertain the type and order of maneuvers that should be used for the treatment of shoulder dystocia, and to determine its correlation with perinatal outcome. ⋯ The McRoberts maneuver and suprapubic pressure should be first-line treatment for shoulder dystocia. More difficult and damaging maneuvers such as Woods screw and delivery of the posterior arm may be reserved for refractory cases. Additional maneuvers are rarely necessary for delivery. The number of maneuvers may serve as a measure of the severity of the shoulder dystocia.
