Re: cervical length in twinsFrom: Dr. John Provatopoulos B.Sc. M.D.C.M. F.R.S.C. (johnprov@sympatico.ca)Fri Jan 30 03:52:32 2004
Thanks for the article art, and Ann you are correct, actually it is likely that a significant number of the article's 87 patients where not just threatened labor but actually latent phase or early active phase. Methods In 87 women with twin pregnancies presenting with regular and painful uterine contractions at 24-36 (median, 30) weeks of gestation, cervical length was measured by transvaginal ultrasound. Women presenting in active labor, defined by the presence of cervical dilation of 3 cm or more, with ruptured membranes and those who underwent a prior or subsequent cervical cerclage, were excluded from the study. For every 0ne of these twins there could have been 4-5 at home with the exact amount of cervical length who never went into prem labor and those didn't show up for sonograms. Such is the nature of early studies the easy things get analyzed first.

Take care, John

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
