"The second stage of labour having commenced, we are summoned to the patient's room, if we have been absent, and told that 'the waters have broken.' She is most likely found reclining on the bed, and, probably, the pains are more urgent than they were before; or, perhaps, they are somewhat suspended. We now require to make another examination, because it is possible that the head may have fully entered the cavity, and may be soon expelled. Finding it low in the pelvis, finding the os uteri almost entirely dilated, the membranes broken, and the pains strong and coming on frequently, it is right not to leave the room; but unless the perineum is somewhat on the stretch, we need not yet take our post exactly by the bed-side. But as soon as the head has come to press upon the external parts--particularly when it has made its turn, and is beginning to extend the structures at the outlet of the pelvis, it becomes our duty to take our seat by the bed-side, and never to move from our position till the child has passed. This we do to protect the perineum, in order to prevent laceration.[28]
"_For the purpose of supporting the perineum_ we sit rather behind the patient, and apply the palm of the left hand--guarded, for the sake of delicacy, cleanliness, and convenience, with a soft napkin--steadily and firmly against the perineal tumour. I have already mentioned that the thighs must be drawn up towards the abdomen, and the legs bent a little back upon the thighs, and the whole person lying on the left side; and the patient is usually placed so that her feet may rest against the bed-post.[29]
"We render the shoulders also another fixed point, so as to steady the upper part of the body, by tying a long napkin, or a round towel, to the same bed-post, and desiring her to hold it in her hand. We tell her, when the pain comes on to press with her feet against the bed-post, and pull gently at the towel, cautioning her against straining violently. The consequence is she so fixes her person as to render it almost impossible for her to jump away suddenly, or to recede to any distance from us. Independently of this little manoeuvring, when the head is in any degree extending the vulva the nurse must be required to raise the right knee to some distance from the other, by which means the thighs are separated, and an increased facility given to the exit of the head through the external parts, as well as some control exerted over the patient's movements.... After having examined the uterus through the parietes of the abdomen, we must make an internal examination, more perfectly to assure ourselves in what way the placenta is disposed of. Twisting the funis umbilicalis around the first two fingers of the left hand, and bringing it to its bearing, we pass the first finger of the right hand, previously anointed, into the vagina, as in a common examination. If the placenta be entirely _in utero_, which, as just remarked, is most commonly the case immediately after the child's expulsion, we shall either not be able to touch it at all, or if it be within reach, we shall only detect a very small portion of it; we may just feel it offering itself at the os uteri; but we cannot surround its volume, nor can we probably discover the insertion of the funis.
