High impact information on Labor Stage, First

  • 600 mg mifepristone, given orally 48 h before surgery, increased the mean preoperative cervical dilatation in both pregnant and non-pregnant treatment groups and also reduced the force required to dilate the pregnant and non-pregnant cervix [7].
  • Using stable isotope, glucose turnover was measured in six normal pregnant women during the various stages of labor; during the latent (A1) and active (A2) phases of cervical dilatation, during fetal expulsion (B), and during placental expulsion (C) [8].
  • The progesterone antagonist RU486, given in late pregnancy to rhesus monkeys at a dose of 47 mmol/ (20 mg/, causes an increase in uterine activity, but not the expected increase in amniotic fluid prostaglandins or cervical dilatation [9].
  • Premature cervical dilatation. American College of Radiology. ACR Appropriateness Criteria [10].
  • The temporal relationship between changes in cervical dilatation, uterine electromyographic (EMG) activity, and maternal plasma concentrations of estradiol 17beta (E(2)), progesterone (P(4)), and 13,14-dihydro-15-keto-prostaglandin-F(2alpha) (PGFM), was investigated in six parturient cows [11].
