This ballad poem, published in 1819, is just one version of the classic folktale. As in many ballads, the refrains of Keats' poem act as a sort of argumentation.
In 1976, Ina May Gaskin described a maneuver for the resolution of shoulder dystocia that involves placing the gravid mother on her hands and knees. (Bruner, 1998) used this procedure in 82 deliveries complicated by shoulder dystocia and was able to resolve it in 68 cases (82%) with this maneuver alone.hile it is incumbent upon all obstetricians to know about the Zavanelli maneuver and how to perform it when a difficult shoulder dystocia occurs, its significant potential for fetal and maternal injury must relegate it to the status of a last ditch procedure.
A conceptually opposite technique of using hexagonal incisions in the periphery of the cornea is known has Hexagonal Keratotomy (HK, described by Antonio Mendez of Mexicali, Mexico), which was used to correct low degrees of Hyperopia.he incisions of RK are used to relax the steep central cornea in patients with myopia. The original technique â consisting of incisions from periphery to center â was called the Russian technique, while the later advances of performing controlled incision from center to periphery was called the American Technique.
