Before applying any traction on the forceps, some checks should be performed to ensure that it is safe to proceed.
- The forceps should not be forced into position.
- The forceps should lock with ease.
- The sagital suture should lie vertically in the midline.
- The blades should be equidistant from the sagital and occipital sutures.
- You should be able to insert a fingertip between the end of the fenestration and the fetal head.
