Abstract

In the March issue there are 2 articles that appear to have errors. The first is the article on “Fetal Pulse Oximetry” by East et al.1East C.E. Brennecke S.P. King J.F. Chan F.Y. Colditz P.B. The effect of intrapartum fetal pulse oximetry, in the presence of a nonreassuring fetal heart rate pattern, on operative delivery rates: a multicenter, randomized, controlled trial (the FOREMOST trial).Am J Obstet Gynecol. 2006; 194: 606-616Abstract Full Text Full Text PDF PubMed Scopus (56) Google Scholar I believe in the Introduction on line 11 where the word “greater” is used, it should be “less.” In the second article on monochorionic twin placentas by Lopriore et al2Lopriore E. Sueters M. Middeldorp J.M. Klumper F. Oepkes D. Vandenbussche F.P.H.A. Twin pregnancies with two separate placental masses can still be monochorionic and have vascular anastomoses.Am J Obstet Gynecol. 2006; 194: 804-808Abstract Full Text Full Text PDF PubMed Scopus (35) Google Scholar they note in the Comments section that the “T” sign or Lambda sign indicates a dichorionic placenta. In 2 cases of monochorionic twin placentas (Number 1 and 3), they note that a “T” sign was seen “suggestive of monochorionic placentas.” These statements are conflicting as the authors wrote that the “T” sign indicates dichorionic, not monochorionic placentas. The effect of intrapartum fetal pulse oximetry, in the presence of a nonreassuring fetal heart rate pattern, on operative delivery rates: A multicenter, randomized, controlled trial (the FOREMOST trial)American Journal of Obstetrics & GynecologyVol. 194Issue 3PreviewThe objective of the study was to compare operative delivery rates for nonreassuring fetal status between 2 groups of laboring women: those having conventional cardiotocograph monitoring and those having cardiotocograph monitoring plus fetal pulse oximetry.

Full-Text PDF ReplyAmerican Journal of Obstetrics & GynecologyVol. 196Issue 1PreviewWe thank Dr Spellacy for carefully reading our article and pointing out the error he noted in our recent publication.1 He is correct in his observation that the word “more” should read “less.” Thus, the second sentence of the introduction should read: “On the basis of human and animal data, fetal oxygen saturation (FSpO2) values 30% or greater are reassuring in the human fetus and FSpO2 values less than 30% for 10 minutes require further assessment or intervention.” Full-Text PDF ReplyAmerican Journal of Obstetrics & GynecologyVol. 196Issue 1PreviewWe thank Dr Spellacy for his concern regarding our paper on bipartite monochorionic twin placentas,1 but disagree with his suggestion that it contains an error or conflicting statement with respect to the sonographic aspect of the intertwin dividing membrane and its predictive value for the prenatal determination of chorionicity. In the Comment section of our article, we elaborated on the importance of correctly determining chorionicity by examination of the type of insertion of the intertwin dividing membrane using prenatal ultrasound.
