To correct an abnormal position the hand is principally used, and the use of instruments should be deferred as long as possible. In most instances reposition by hand is possible, and the parts in the parturient passage can be secured after reposition. With practice, decided dexterity is acquired, and disagreeable complications are less liable to follow birth. Cords are often necessary; hooks, porte-cords, etc., can be often dispensed Figs. 27 and 21a. Instruments Used in Repositions.—Of the many obstetrical instruments, to which new ones are constantly added, only a small number are of use. Although the discussion shall touch upon many useless instruments, a description of the various mechanical means is indicated. One of the most useful agents is hemp-rope, usually 2 m. long and 7 mm. in diameter. A loop is on the one end, the other one being wrapped with string to prevent its unraveling. Thin cords hold better, but soon cut the parts. Thin cords, of course, may be doubled and a doubled noose be made (figs. 27 and 27rt). Many obstetricians prefer for the head and legs a web 3 cm. wide and 2 m. long, or a band. They have the advan- tage of being more pliable; do not slip and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bruin, M.
