To clarify the peculiarities of the course of labor, the postpartum period, and the condition of newborns, we analyzed 102 labor histories of women whose pregnancies were complicated by the threat of termination in different terms. Morphological examination of the placenta was performed concurrently in these women in labor. The age of the examined women ranged from 18 to 35 years.

We observed 23 women who developed peritonitis after cesarean section. The average age of the patients was 28.9 years. There were 7 first-pregnant women and 16 second-pregnant women. The anamnesis revealed the presence of endogenous foci of infection in all the patients. Thus, flu, sore throat, acute respiratory infections were diagnosed in 20 women, pneumonia in 3; chronic pyelonephritis in 5, inflammatory uterine appendages in 6, rheumatism with mitral valve insufficiency in 1, Botkin disease in 1. Genuine pregnancy was preceded by abortions in 19 women, of whom 11 had formal abortions, 3 had criminal abortions, and 5 had spontaneous abortions at 10 to 25 weeks' gestation against a background of chronic pyelonephritis and inflammatory diseases of the uterine appendages.

Infected abortions remain the main source of septic complications. Most authors point out the sterile course of peritonitis in gynecological patients and the difficulty of its diagnosis, which confirms the relevance of the issue under study.1132 women with infected abortions were under observation, 26 of them (2.3%) were diagnosed with peritonitis. The average age of patients with peritonitis was 25,6 years. On the 2nd-3rd day after the intervention and the first signs of disease 17 patients were admitted, on the 5th-6th day - 8 patients. To terminate the pregnancy women injected vodka (6), rubber catheters (14), metal objects (2), and oral medications (4) into the uterine cavity. Uterine perforation due to the introduction of metal objects occurred in 2 patients.

The purpose of this study was to develop methodological and organizational foundations for the prevention of pregnancy and childbirth complications in female workers in the machine-building industry.

There were 2,659 women with intrauterine devices produced by the Kazan Medical and Instrumental Plant under observation. 122 women were observed up to 3 months, 152 - up to one year, 1906 - from one to 5 years, 445 - up to 7 years, 34 - more than 10 years. The efficacy of intrauterine devices reached 97.6% according to our observations. The control group consisted of 218 women who used synthetic progestins (Bisecurin, Non-Ovlon) for contraception according to the usual scheme: one tablet a day from the 5th day of the cycle.
