The impact of non-significant variable decelerations appearing in the latent phase on delivery mode: a prospective cohort study

<p>Abstract</p> <p>Background</p> <p>Variable decelerations are the most frequent fetal heart rate changes that are related to labor. The objective of the study was to estimate the impact of non-significant variable decelerations (NSV) appearing during the latent phase of labor on delivery mode and neonatal outcome.</p> <p>Methods</p> <p>Women at term, who were in the latent phase of labor and had a singleton pregnancy, were prospectively included. Women were divided into three groups. All had a fetal heart rate tracing with normal baseline and variability. The study group was composed of women who had in addition NSV, Category II, according to the National Institute of Child Health and Human Development categorization system. Women who had Category I tracings composed the control group. Women who had non-repetitive severe variables (SV) composed a second control group (Category II-SV). Main outcome compared was mode of delivery. Secondary outcome was cord pH. One-way analysis of variance was used to compare the continuous demographic and clinical variables of the three groups. Backwards stepwise logistic regression using significant univariables was performed to determine which predicted operative delivery. P < 0.05 was considered significant.</p> <p>Results</p> <p>Of 1005 women who delivered during the study period 186 had Category II- NSV tracings (study group), 76 had Category II-SV and 251 had Category I tracings. Mode of delivery and indications for operative delivery were similar between women in Category II-NSV compared to Category I. In addition mean cord pH did not differ between the two groups. Conversely, women in Category II-SV, had a higher rate of cesarean or vacuum deliveries compared to the other groups (p = 0.0001). Beside, they had a significantly higher number of neonates born with cord pH between 7.0 to 7.1 (p = 0.03).</p> <p>Conclusions</p> <p>Non-significant variable decelerations in early stages of labor are probably a non-ominous sign for neonatal outcome and have no impact on delivery mode.</p

Comparison between amniotomy, oxytocin or both for augmentation of labor in prolonged latent phase: a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>A prolonged latent phase is independently associated with an increased incidence of subsequent labor abnormalities. We aimed to compare between oxytocin augmentation, amniotomy and a combination of both on the duration of labor among women with a prolonged latent phase.</p> <p>Methods</p> <p>Women with a singleton fetus in cephalic presentation who have a prolonged latent phase, were randomly allocated to amniotomy (group 1), oxytocin (group 2) or both (group 3). A group of women who progressed spontaneously without intervention composed the control group (group 4). The primary outcome was the duration of time from initiation of augmentation until delivery.</p> <p>Results</p> <p>A total of 213 women were consented and randomized to group 1 (70 women), group 2 (72 women) and group 3 (71 women). Group 4 was composed from additional 70 women. A mean reduction of 120 minutes in labor duration was observed among group 3 compared to group 1 (p = 0.08) and 180 minutes compared to group 2 and 4 (p = 0.001). Women in group 3 had a shorter length of time from augmentation until the beginning of the active phase and a shorter first stage of labor than group 1 (p = 0.03), group 2 (p = 0.001) and group 4 (p = 0.001). Satisfaction was greater among group 3 and 4. Mode of delivery and neonatal outcome were comparable between the groups.</p> <p>Conclusion</p> <p>Labor augmentation by combined amniotomy and oxytocin among women with a prolonged latent phase at term seems superior compared to either of them alone.</p

The impact of close surveillance on pregnancy outcome among women with a prior history of antepartum complications attributed to thrombosis: a cohort study

<p>Abstract</p> <p>Background</p> <p>There is limited evidence, so far, as to the optimal management of women with a prior obstetric history of antepartum complications attributed to thrombosis. We aimed to investigate the contribution of close antepartum surveillance on pregnancy outcome among women with prior antepartum complications attributed to thrombosis.</p> <p>Methods</p> <p>The study was conducted on all women who were delivered, conceived and delivered again between January 2000 and January 2006 at a university teaching hospital. Women included were managed in previous pregnancy at a low risk setting and had unpredicted antepartum complications occurring at a gestational age of 23 weeks or more. Antepartum complications considered were intrauterine fetal death, neonates who were small for gestational age, severe pre-eclampsia and placental abruption. All women were tested for the presence of thrombophilia after delivery. In the following pregnancy, only women found to have any thrombophilia (thrombophilic group) were treated with enoxaparin. Both the thrombophilic group and the non-thrombophilic group (tested negatively for thrombophilia) were managed and observed closely at our high-risk pregnancy clinic.</p> <p>Results</p> <p>Ninety-seven women, who conceived at least once after the diagnosis of the relevant antepartum complications, were included in this study. Forty-nine had any thrombophilia and 48 tested negatively. Composite antepartum complications (all antepartum complications considered) were reduced significantly after close antepartum surveillance in both groups. Mean birth weight and mean gestational age improved significantly and were comparable between the groups.</p> <p>Conclusion</p> <p>Close antepartum surveillance may contribute to improvement in the perinatal outcomes of women with prior antepartum complications attributed to thrombosis.</p

Postprandial glycemic control during gestational diabetes pregnancy predicts the risk of recurrence

Abstract In this study we aimed to explore the significance of glycemic control during gestational diabetes mellitus (GDM) pregnancy in predicting recurrence as this is unknown. A retrospective population-based cohort study of women with first diagnosed GDM pregnancy was conducted. A total of 426 women with 4,226 glucose charts were obtained. Daily glucose values were collected from the glucose charts. Non-parametric (LOWESS) regression was used to present the glucose measurements along the gestational weeks. The analyses revealed that the 2-hour postprandial levels among women with GDM recurrence were substantially higher throughout gestation (PR = 1.89 [95% CI: 1.33, 2.73] for every 20 mg/dl increase). In a multivariable log-binomial regression, the mean postprandial glucose was significantly associated with GDM recurrence (p = 0.017) after adjusting for maternal age, family history of diabetes, insulin use, and inter-pregnancy interval (PR = 1.04 [95% CI: 1.01, 1.07]). The study conclusion is that tighter postprandial glycemic control should be considered. Future studies should explore tighter cutoffs of the 2-hour postprandial glucose
