The purpose of this study is to evaluate the effects of propoxyphene napsylate on the pregnancy of the rat. We used fifty pregnant rats divided into five groups. All the animals received daily 1 ml of the solution by gavage from day 0 to the 20th day of pregnancy. Group I - only distilled water (control); group II - aqueous solution of acacia 2% (vehicle); groups III, IV and V - respectively, 5, 15 and 45 mg/kg of weight of propoxyphene napsylate diluted in 2% acacia solution. The animals were weighed on days 0, 7, 14 and 20 of pregnancy. All animals were sacrificed on the 20th day of pregnancy. Our results showed that the animals treated with 45 mg/kg of propoxyphene napsylate presented reduction of the individual weights of the fetuses, as well as of the weights of the newborns and placentas. The difference betewwn number of resorptions, implantations and placentas of the treated groups was shown to be non significant cohen compered with the control groups.

In pregnant women with cervical incompetence in whom there is also dilatation of the cervix and prolapsed membranes there are technical difficulties in performing cerclage in order to prolongate pregnancy until sufficient fetal maturity assures survival of the newborn. We describe a case of cervical incompetence with prolapsed membranes at 21 weeks of gestation, in which we caused the decrease of intrauterine pressure with drainage of amniotic fluid by amniocentesis, until reintroduction of membranes into the uterine cavity was possible. This procedure allowed traction of cervical lips and cerclage with less mechanical trauma, warranting the evolution of pregnancy for 12 weeks and fetal survival
