Henci,

I am looking for information about post date babies and placenta deterioration. Do you know of any research linking the two? Thanks!

RE: placenta deterioration

Here is a quote from Chapter 37 Postterm Pregnancy from Williams' Obstetrics: PLACENTAL DYSFUNCTION Clifford (1954) proposed that the skin changes of postmaturity were due to loss of the protective effects of vernix caseosa. He also attributed the postmaturity syndrome to placental senescence, although he did not find placental degeneration histologically. Still, the concept that postmaturity is due to placental insufficiency has persisted despite an absence of morphological or signficant quantitative findings (Larson and co-workers, 1995; Rushton, 1991). In Chapter 27 of Williams' Obstetrics (page 621) Degenerative Placental Lesions' Extensive calcification is found in 10 to 15 percent of all placentas at term. This can be seen with sonography, and Spirt and colleagues (1982) reported that by 33 weeks more than half of placentas have some degree of calcification. It is difficult to correlate the degree of calcium deposition with pregnancy outcome (Benirschke and kaufmann, 2000). To summarize, placental changes such as calcification are common and do not predict pregnancy outcome. Placentas from babies born with postmaturity findings have not been found to have any telltale signs. According to an obstetrical textbook. tienchin
