For some time after child-bearing, a discharge takes place from the womb which is called lochia. It is at first red; but if all goes well, in a few days the red appearance subsides and gives place to an effusion of a greenish color and a peculiar odor. When the womb is reduced to its original size, the lochia ceases. If it is checked before it should be -- and in some women it ought to continue a month -- or if the flow proceeds with irregularity, great distress and danger are the consequences. The immoderate flow of the lochia is not so disastrous as the suppression. The latter may be produced by cold, by chilled drink, by mental excitement, or, in fact, by any undue exertion of either mind or body. The results of the suppression of the lochia are great fever, restlessness, heat, pain in the head, back, and loins, delirium, inflammation of the womb, colic pains, costiveness, nervous excitability, muscular contractions, and, in fact, general distress. The first and only thing to be done is to restore the flow. For this purpose, if the patient can bear it, the warm bath must be used; fomentations should be applied to the abdomen; large emollient injections should be given in the rectum, and sudorific medicines (not of a mineral character), assisted by copious diluent drinks, should be administered. The acetate of ammonia will be found very useful. A profuse and general perspiraton is the precursor of rapid recovery and safety. While the lochia is apparent the patient must not endeavor to get up, or to undergo any noticeable degree of exertion, or be exposed either to atmospherical changes, or imprudence in diet.
