The practice of obstetrics, designed for the use of students and practitioners of medicine . ce ofa mesentery, and by the characteristic twists of the umbilical cord which can befelt, and, if the child still lives, by the presence of pulsation in the cord. Insome cases, however, pulsation in the cord ceases a short time before the deathof the child, so that the heart should be auscultated before death is decided tohave occurred. If the membranes are still unruptured and the pulsation is ab-sent, the diagnosis is not quite so clear. Pulsations which occur in the vaginalor uterine arteries may be distinguished from those of the cord by being syn-chronous with the pulse of the mother. Before the escape of the liquor amnii,the cord, being non-resisting, is pushed ahead of the examining finger until it isreally beyond palpation. Prolapsed cord has also to be differentiated from thepresence of a foot or a hand in the vagina, an ectopia of the fetal intestines, andan oedematous and lacerated lip of the cervix. Prognosis.—The mortality among children in this condition amounts to 50. Fig. 700.—Prolapse of the Cord inVertex Presentation. FETAL DYSTOCIA FROM FAULTY ATTITUDE. 525 per cent. The prognosis for the child depends on the time of labor at which theprolapse occurs, the presentation and position of the fetus, the condition of themembranes, the condition of the cervix, the amount of cord prolapsed, and thegravity of the abnormality causing the accident. The great danger for the childis from asphyxia due to compression of the cord. Head presentation carries thegreatest danger with it. The danger is less in proportion to the greater length oftime that the membranes remain intact, and, after their rupture, in proportion tothe rapidity of delivery. The amount of the cord prolapsed and the region of thepelvis into which it descends also influence the prognosis. The fetal mortalityis higher in primiparae and in oversize of the fetus. The prognosis for the mother depends up
