Sometimes the hand comes down in the vagina or even appears at the vulva; if it does we may know by that (and by slipping the finger of our hand up into the axillary space) just how the child lies. If the back of the child’s hand is turned towards the mother’s right thigh the head is to the right, and if to the left thigh, to the left. The little finger being towards the coccyx indicates that the child’s back is towards the mother’s loins, and the same finger being towards the pubis is evidence that this is in front. It is quite important that these points should be noted.
There are various causes of tedious, difficult and obstructed labor, and in each case we are obliged to depend principally upon the touch for diagnosis. In some instances the difficulty will be obvious as soon as we attempt to make an examination. A NARROW and UNDILATABLE VAGINA will be easily recognized, but this will rarely be found a serious obstacle to the passage of the child; as the labor proceeds the vagina seems naturally to dilate and to be more softened and relaxed.
Cases have been reported where there was a scirrhus tumor or cancer connected with the neck of the uterus, even during labor; happily such cases are rare. The scirrhus would be felt hard and unyielding. A tumor of any kind connected with the os uteri, the vagina or the rectum may obstruct the descent of the child’s head more or less according to its size and mobility. Of course they can be detected.
A VAGINAL CYSTOCELE ought always to be rectified. It sometimes happens that the bladder is caught by the head of the child in its descent into the cavity of the pelvis and pushed before it, and it can be seen as a soft red tumor between the vulva. The finger can be passed posterior to it, but not anterior, and the catheter cannot be passed in the usual direction.
A few cases are on record where a stone (calculus) in the bladder was pushed down before the fœtal head. A careful examination will show that the tumor is covered by the bladder; its hardness will indicate its nature.
A collection of hardened feces in the rectum is detected without difficulty. It will be of an irregular form, hard and inelastic.
Swelling of the soft parts may cause obstruction. If the child’s head is detained for a long time pressing upon the brim of the pelvis, it may obstruct the circulation and diminish the capacity of the passage. In such cases there is unusual heat and dryness in the parts.
When a nurse or midwife makes an examination by touching, she needs to continue it through several pains, and to repeat it again soon to know if there is any progress to the labor. If the progress is very slow this may be from various causes, some of which I will now simply name. It may be because the uterus is very much distended, and this renders the pains inefficient; there may be partial and irregular contractions of the uterus, weakness of constitution, fever or local inflammation, a want of irritability in the constitution, a deformity of the pelvis and spine, or doubts and fears on the part of the patient may diminish the action of the uterus. The labor may be slow because it is the first one, or because the membranes were ruptured too early, or because the woman is advanced in years at the time of having her first confinement. The uterus may be pitched over obliquely, there may be extreme rigidity of the os uteri, extreme rigidity of the soft parts of the mother, a contracted or small pelvis, the head of the child may be large and ossified so as to be unyielding. One or both arms may come down by the side of the head of the child; on the part of the mother there may be a distended bladder from inability to void the urine, there may be cicatrices (scars) or adhesions of the vagina, and in some cases it has happened that an enlarged ovary has dropped down into the pelvis, or a portion of intestine containing scybala or hardened feces obstructs the passage, or the os uteri is very minute, or imperforate, or totally absent.
Some of these cases may demand the interference of art in the first stage of labor, but delay at that time involves very little danger; as a rule neither the mother nor child is in danger (except when there is hemorrhage or convulsions) on account of labor before the membranes are broken. If the nurse can ascertain the cause of the delay and finds that time is what is especially needed, she must exercise patience herself and encourage her patient to do so.
It is hardly possible to predict beforehand in what cases convulsions will occur, but if there is much headache in the commencement of labor and if there has been considerable albumen in the urine of the patient, we have especial reason to apprehend trouble of that kind.
