A textbook of obstetrics . the fetal traction bars are then sprung loose at their lower end and the handle is adjusted to them andlocked. Traction should be made in a line as nearly as possiblecoinciding with the axis of the pelvic inlet—namely, backwardand downward. To do this even approximately the woman mustbe placed upon a bed or table with her buttocks projecting wellbeyond the cdi^c and the axis-traction handle of the forceps mustbe pulled downward and backward as far as possible. To pro-tect the perineum from injury by the traction rods a Sims specu-lum should be held in place
A textbook of obstetrics . the fetal traction bars are then sprung loose at their lower end and the handle is adjusted to them andlocked. Traction should be made in a line as nearly as possiblecoinciding with the axis of the pelvic inlet—namely, backwardand downward. To do this even approximately the woman mustbe placed upon a bed or table with her buttocks projecting wellbeyond the cdi^c and the axis-traction handle of the forceps mustbe pulled downward and backward as far as possible. To pro-tect the perineum from injury by the traction rods a Sims specu-lum should be held in place during the tractive efforts. Betweenthe tractions the bar joining the handles should be unscrewed andthrown out of place and the pin-lock should be unscrewed, thusrelieving the fetal head from continued pressure. As soon as thefetal head has descended well into the pelvic cavity the axis-trac-tion principle becomes unnecessary. The handle should, therefore,be removed, the bars fastened in their places by the blades, and.
