MANAGEMENT OF THE PLACENTAL STAGE OF LABOR.

Fehling (Sammlung Klin. Vorträge, No. 308) compares the views and

practice of authorities in the treatment of the third stage of labor.

The various methods of placental delivery that have been advocated by

different writers are recounted. The reaction against Credé in favor of

expectancy, first started by Dohrn and Ahlfeld, has resulted in proving

the inferiority of the latter plan, and in a return to more active

methods. In a large number of German clinics, the uterus is allowed to

rest immediately after the expulsion of the child, without friction.

When the placenta lies detached in the lower uterine segment, which is

generally the case after fifteen or twenty minutes, nothing is to be

gained by longer waiting. The author is favorably disposed toward the

practice of Credé, which as he says, has never been shown by its

adversaries to be capable of harm when properly conducted. With

reference to the mechanism of placental separation, both theoretical

considerations and clinical observations favor the views of Duncan, yet

the question is not settled. Retained membranes may be removed with the

aseptic hand. Yet Credé and Olshausen consider the retention of even the

whole chorion free from danger, and clinical experience has shown better

results by the expectant plan in case of retained membranes than by

interference. These results, the author thinks, in the light of

Döderlein’s researches, are explained by the fact that the hand may

transport the peccant germs from the vagina into the uterus. The active

plan, with a preliminary vaginal disinfection and a vigorous asepsis

throughout, should yield better results than expectation. Interference

with these precautions is, at least, justified in case of atony and

hæmorrhage or fever, including, if need be, the use of the curette and

subsequently ergot. Dührssen’s method of tamponing the uterus in

post-partum hæmorrhage with iodoform gauze is favorably mentioned.

In the event of cervical tears causing troublesome hæmorrhage,

Kaltenbach, Schroeder and Leopold practice immediate suture. The author

thinks the vaginal tamponade is generally to be preferred. Yet, in

certain cases the suture may also be required, or the application of the

perchloride of iron on cotton pledgets to the bleeding surfaces.

Credé (Arch. f. Gyn., B. 32, H. 1) again discusses and defends his

method of managing the placental delivery which he prefers to call the

external method.

The duration of the third stage need not in the majority of normal

labors exceed fifteen to thirty minutes. In many instances a more

expectant plan of treatment is better. In occasional cases more rapid

delivery is demanded in the interest of the mother. Since the method is

free from danger when properly conducted, the expulsion of the placenta

may be hastened within reasonable limits if for no other purpose than to

save the time of the attendants and to spare the sufferings of the

patient. He claims that the amount of blood-loss is diminished under his

treatment of the placental stage, and that the membranes are not more

frequently retained. Furthermore, he believes the retention of portions

of the membranes or placenta to be harmless in an aseptic condition of

the passages.

The method of Credé, briefly restated, is as follows: First apply

gentle, painless friction in a circular direction over the anterior wall

of the uterus, laying the hand flat upon the abdomen. Bring the axis of

the uterus in conformity with the axis of the pelvic inlet. If the

placenta is not expelled after three or four pains assist the next

contraction, at its acme only, by compressing the upper segment,

grasping the fundus with the thumb in front and the fingers behind, at

the same time using gentle downward pressure. Use slight friction only

but no compression during the intervals between the pains nor even

during the contraction except at its height. Success usually attends the

eighth or tenth pain.
