If a uterus is flexed it is easy to poke a curette or like instrument through it at the bend, especially if the uterus is thin or friable from sepsis. Again, the placental site is raised, it feels rough, and the furrows in it lead one to think part of the placenta is still adherent, whereas all has been removed. Repeated scraping, due to this error, may dig a hole through the uterine wall. Perforation in a septic case is practically always fatal to the woman. The use of the curette supposes a special technic, and no physician should presume to try its use unless he has been carefully and practically instructed. In inevitable abortion after the third month it may be very difficult to get the embryo out. The cervix, in primiparae especially, may be long, thick, and hard. If the fetus is dead, it may then be removed by _morcellement_--_i. e._, by cutting and breaking it into pieces, and then taking out these pieces with an ovum or stone forceps. Sometimes, though rarely, the operator may find it impossible to get the entire fetus away. Then the uterus is packed with weak iodine gauze, and after twenty-four hours the fetal remains are expelled. In every abortion the presence or absence of extrauterine pregnancy is to be made out. If there is an extrauterine pregnancy, curettage will cause rupture of the sac. When the interior of the aborting uterus has become septic the old treatment was to empty the uterus at once, but now the treatment is expectant, because the traumatism of the curetting makes the sepsis worse. The commonest and worst infections are of the streptococcus putridus, a pus staphylococcus, and the bacterium coli communis. Curettage lets these microörganisms enter the circulation. The cause of this condition is often unskilful attempts at artificial abortion. When the womb contains decomposing material bleeding usually obliges tamponing, and thus often the uterine contents come away in twenty-four hours with the gauze. If there is no hemorrhage there should be no tamponing: it is then better to get dilatation by packing and drain the uterus with gauze. The curette should not be used at all. Where there is habitual abortion the cause must be found. During gestation syphilis and displacements of the uterus, as causes, may be treated. Endometritis can be cured only when the uterus is empty. Rest in bed at the time when these abortions usually occur, and at the time when menstruation customarily appears, is required. Treatment of the husband is often necessary, as he is virtually always the source of luetic infection.
