How to read fetal heart rate tracings in labor: a comparison between ACOG and NICE guidelines.

The aim of this study was to assess reproducibility and clinical relevance of current guidelines on fetal heart rate interpretation in labor. Two obstetricians with comparable experience analyzed one hundred fetal heart rate tracings. One doctor made a first analysis using American College of Obstetricians and Gynecologists (ACOG) 2009 guideline's criteria; the other used National Institute for Health and Clinical Excellence (NICE) 2007 guideline's criteria; subsequently they repeated the evaluation crossing the guidelines used.

The effects of maternal caffeine and chocolate intake on fetal heart rate.

Objective: The aim of our study was to analyze the effects of caffeine and chocolate (70% cocoa) on fetal heart rate (FHR).

Study Design: Fifty pregnant women with uncomplicated gestation, matched for age and parity, underwent computerized FHR recording before and after the consumption of caffeine and then, after one week, before and after 70% cocoa chocolate intake. Computerized cardiotocography (cCTG) parameters were expressed as mean and SD.

Computerized analysis of fetal heart rate in pregnancies complicated by gestational diabetes mellitus, gestational hypertension, intrauterine growth restriction and premature rupture of membranes.

Objective: We aimed to compare individual fetal heart rate (FHR) indices, as determined by computer analysis of the tracing, in pregnancies complicated by gestational diabetes mellitus (GDM), gestational hypertension (PIH), intrauterine growth restriction (IUGR) and premature rupture of membranes (pPROM).

Methods: The study population consisted of 100 pregnant women affected by GDM on diet therapy, 100 pregnant women affected by GDM on insulin therapy, 100 pregnant women affected by PIH, 100 pregnant women affected by IUGR, 100 with premature rupture of membranes far from the term (pPROM) and 100 normal pregnancies matched for age, parity and gestation as controls. The 30-min FHR tracing was analyzed by computer.

Computerized analysis of fetal heart rate in pregnancies complicated by gestational diabetes mellitus.

Objective: We evaluated the value of computerized cardiotocography (cCTG) in pregnancies complicated by gestational diabetes mellitus (GDM). Purpose of study. We studied fetal heart rate (FHR) recordings from 100 pregnant women affected by GDM on diet therapy, 60 pregnant women affected by GDM on insulin therapy and 100 normal pregnant controls.

Deceleration area of fetal heart rate trace and fetal acidemia at delivery: a case-control study.

Objective: To assess the correlation between the total deceleration area of the fetal heart rate (FHR) pre-delivery trace and intrapartum fetal acid-base status in a low risk population.

Study Design: We analyzed the electronic fetal monitoring (EFM) traces of 26 pregnancies with fetuses presenting acidemia at delivery and those of thirty controls. All laboring patients had at least 1 hour of EFM without interruption.
