Abstract

Can we influence the mechanism of labor by external pressure over the sacro-sciatic foramen? is the question asked by Dr. A. F. A. King in a communication in the American Journal of Obstetrics, of May. While examining some cadavers he found that such pressure produced an elevation or protrusion at the same point in the interior of the pelvis. Having removed the uterus and appendages, he anointed the pelvic cavity with vaseline, and placed in the pelvis a good-sized, recent fœtal head, also anointed with the vaseline. The head was placed low down in the pelvic cavity, with the occiput towards an acetabulum, and the forehead towards the opposite sacro-sciatic synchondrosis. Pressure with the finger-ends over the sacro-sciatic foramen towards which the forehead was directed easily caused the head to rotate, bringing the forehead to the sacrum and the occiput to the pubis.

Could the same thing be done on
