[Prevention of hypotonic hemorrhage in the placental and early puerperal period with prostenone]. / Profilaktika gipotonicheskikh krovotechenii v poslerodovom i rannem poslerodovom periodakh prostenonom.

To prevent afterbirth and early postpartum hemorrhages the authors used prostenone in 46 (the main group) and oxytocin in 20 females (control group). Intraplacental blood pressure and coagulation parameters were studied. With prostenone, the mean amount of the blood loss turned to be significantly lower (137 +/- 13 ml) than with oxytocin (208 +/- 17 ml). Administration of prostenone led to a significant elevation of prothrombin index alone and tolerance to heparine. As there was an insignificant difference between the parameters in the main and control groups, the mechanism of prostenone's effect on the myometrium required further studies.
