[Structural and morphofunctional changes in the endometrium after postpartum insertion of the intrauterine device]. / Strukturnye i morfofunktsional'nye izmeneniia éndometriia pri vnutrimatochnoi kontratseptsii, primenennoi posle rodov.

PIP: Morphological and histochemical endometrial findings in 90 women with Lippes Loop IUDs, inserted postpartum and used for 20-50 months, are presented. Endometrial morphofunctional changes were delayed in 33 women, and inflammatory infiltrates in the endometrial stroma and leucocytes in the uterine glandular lumen were established in 37 women. These changes are not regarded as signs of endometritis but appear to be the means by which the IUD exerts its contraceptive effect on a number of patients. (author's modified)^ieng

[Regional hemodynamics in intrauterine contraception in the early puerperium]. / Regionarhaia gemodinamika u rodil'nits pri vnutrimatochnoi kontratseptsii v rannie sroki posle rodov.

PIP: Research has shown that the introduction of an IUD 5 days after birth is effective. In this connection it is interesting to study the regional redistribution of blood--in the brain, the pelvis and the lower extremities--which was the object of this investigation. The subjects were 40 healthy women, and a 4-channel rheograph connected to an 8-channel encephalograph was used. Rheograms were taken before introducing the IUD and afterwards (after 6 hours, 1 day, and 1 month). We wanted to establish the basic blood flow in the organs, the response of the organ to the IUD in terms of regional hemodynamics, and the changes that occurred a month later. We found that 2 basic physiological variants in the distribution of blood between the center and the periphery occur in women after birth: either the distribution is even or there is preference for one or the other, depending on the characteristics of the woman. Our data indicate that by the 4th day after delivery these differences disappear, and introduction of the IUD does not disturb the process of uterine involution. The hypothesis that the reduced excitability of the neuromuscular apparatus of the uterus contributes to expulsion of the IUD when introduced shortly after birth will serve as the basis for more differentiated selection of women for this type of contraception.^ieng

[Experience in the use of IUDs and the risk of inflammatory genital diseases in inserting them in the early period after birth]. / Opit v prilaganeto na VMS i riskut ot vuzpalitelni zaboliavaniia na genitaliite pri postavianeto im v rannite srokove sled razhdaneto.

PIP: To evaluate a possible risk of development of inflammatory diseases of the genital organs in IUD users, 410 women in whom IUD was inserted on day 5 after normal delivery were followed up for 3 years. The follow-up included gynecologic, colposcopic, and bacteriologic examinations. IUD insertion shortly after childbirth did not affect the course of the puerperal period. Within the 1st 3-6 months, 13% of the women showed expulsion of the IUD and had to undergo the reinsertion of the device. The IUD did not increase the incidence of vaginal discharge (6%, compared with 6.3% reported in the literature). Bacteriologic examination of the vaginal and cervical content showed prevalence of cocci and gram-positive bacteria identical to those in women who did not use the IUD. Histological examination of the endometrium in 65 women indicated chronic endometritis in 4 and foci of the perivascular and periglandular round cell and leukocytic infiltration indicative of a local nonspecific immune response to the foreign body in 26. Among these 65 women, 15 showed proliferative phase of the endometrium, 24 showed early secretory phase and 26 showed secretory phase. The state of the endometrium corresponded to the phase of the menstrual cycle in 41 of 65 women. It was concluded that the incidence of complications in women subjected to IUD insertion after childbirth did not exceed that of the general population.^ieng
