OBJECTIVE: To determine whether the incidence of hypotension or adverse fetal heart tracing (FHT) category change differed following antepartum administration of intravenous (IV) labetalol versus hydralazine. METHODS: Blood pressure and FHT categories were assessed one hour before and after medication administration. Hypotension was defined as ≥30% reduction in baseline systolic blood pressure (SBP) or SBP <90 mmHg. Changes in mean arterial pressure (MAP) were also compared...

BACKGROUND: Spontaneous hematoma of the umbilical cord is a rare, unpreventable, and dramatic event mainly due to a disruption of the vascular wall, often resulting in adverse perinatal outcome. CASE: We describe a case of a term fetus with acute hemorrhage in the cord occurred intrapartum during spontaneous vaginal delivery. No iatrogenic factors were involved because no drugs, obstetric instruments, or procedures were applied. Umbilical hematoma probably developed in a time frame of 90 seconds, when the electronic fetal monitoring tracing detected a loss of fetal heart rate...

INTRODUCTION: The Sense4Baby system is a novel, wireless, noninvasive maternal and fetal monitor that locally transmits cardiotocography data and uploads it for a clinician. This device can help address health care disparities in high-risk pregnant women in underserved and remote areas by capturing and relaying data in a more cost-effective manner. The clinical use of the recording and interpretation capability of the Sense4Baby system device was compared with a U.S. Food and Drug Administration-approved predicate cardiotocograph (Philips system)...

REVIEW
Gloria T Too, James B Hill
Hypertension affects 10% of pregnancies, many with underlying chronic hypertension, and approximately 1-2% will undergo a hypertensive crisis at some point during their lives. Hypertensive crisis includes hypertensive urgency and emergency; the American College of Obstetricians and Gynecologists describes a hypertensive emergency in pregnancy as persistent (lasting 15 min or more), acute-onset, severe hypertension, defined as systolic BP greater than 160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia...

BACKGROUND: Using the naked eye, evaluation of fetal heart-rate (FHR) patterns remains difficult and is not complete. Computer-aided analysis of the FHR offers the opportunity to analyse FHR patterns completely and to detect all changes possibly due to hypoxia and acidosis. It was the goal of this study to make these hypoxic changes of the FHR visible and to compare them directly with normal tracings. METHODS: During a period of 11 years the FHR signals (i. e., R-R intervals of the F-ECG) of 646 fetuses were recorded simultaneously also by a computer...

BACKGROUND: Using naked-eye evaluation of foetal heart rate (FHR) patterns remains difficult and is not complete. Computer-aided analysis of the FHR offers the opportunity to analyse the FHR completely and to detect all changes due to hypoxia and acidosis. In order to better understand these changes FHR patterns in non-acidotic foetuses should be studied by first separating FHR into (i) basal FHR (baseline) and (ii) all decelerations. METHODS: The FHR signals (i...

We undertook this study in order to compare the efficacy of 25 microg versus 50 microg of intravaginal misoprostol for cervical ripening and labour induction at term. The study population consisted of 120 women with term singleton pregnancies in vertex presentation booked for caesarean section. They had a Bishop scoring of <6 and a reactive fetal heart rate tracing. They were randomized into two groups, A and B, to receive 25 microg and 50 microg of vaginal misoprostol, respectively, 4 hourly with a maximum of five doses until the patient had three contractions in 10 minutes...

OBJECTIVE: To determine whether early initiation of neuraxial analgesia (anesthetic[s] placed around the nerves of the central nervous system) compared with systemic opioid analgesia, followed later in labor by epidural analgesia, increases the rate of cesarean delivery in nulliparas undergoing induction of labor. METHODS: Nulliparas undergoing induction of labor who requested analgesia when cervical dilation was less than 4 cm participated in the study. Patients were randomized to neuraxial (early) or systemic opioid (late) analgesia at the first analgesia request...

OBJECTIVES: Prolongation of the QT interval is a risk factor for sudden death. Selective serotonin-reuptake inhibitor antidepressants can prolong the QT interval and are widely used by pregnant women. Whether antenatal exposure to selective serotonin-reuptake inhibitor causes QT prolongation in offspring is unknown. The aim of this study was to determine the effect of maternal use of selective serotonin-reuptake inhibitor antidepressants during pregnancy on the QTc interval of the offspring...

The purpose of this randomized, double blinded and controlled study was to determine the optimal dose of intrathecal fentanyl when combined with bupivacaine 2.5 mg for initiation of labor analgesia. Parous parturients with cervical dilation between 3 and 5 cm were randomized to receive intrathecal fentanyl 0 (control), 5, 10, 15, 20 or 25 micrograms, combined with bupivacaine 2.5 mg, followed by a lidocaine/epinephrine epidural test dose. Visual analog pain scores (VAPS) and the presence of side effects were determined every 15 min until the parturient requested additional analgesia...

UNLABELLED: Combined spinal epidural analgesia (CSE) for labor pain relief has become increasingly popular. However, the effect of intrathecal sufentanil on the incidence of uterine hyperactivity and fetal heart rate (FHR) abnormalities remains controversial. We hypothesized that the use of intrathecal sufentanil in a dose of 7.5 microg is more likely to induce a nonreassuring FHR tracing than a small dose of spinal sufentanil combined with bupivacaine or epidural analgesia. Three-hundred parturients were randomized into three groups...

In this study, we have compared two different doses of clonidine (bolus of 25 micrograms and infusion of 19 micrograms h-1; bolus of 50 micrograms and infusion of 37 micrograms h-1, both added to 0.03% bupivacaine) with a control group of 0.03% bupivacaine alone. The study was performed in a randomized, double-blind manner, and a total of 45 patients were studied. Both clonidine regimens resulted in marked local anaesthetic sparing, with no change in the quality of analgesia. There was no difference in the severity of lower limb motor weakness and no difference in maternal sedation, although only a small number of patients were studied...

BACKGROUND: Intrathecal clonidine produces dose-dependent postoperative analgesia and enhances labor analgesia from intrathecal sufentanil. The authors evaluated the dose-response potency of intrathecally administered clonidine by itself during first stage of labor with respect to analgesia and maternal and fetal side effects. METHODS: Thirty-six parturients requesting labor analgesia were included in this prospective, randomized, double-blind study. Parturients with < 6 cm cervical dilatation received either 50, 100, or 200 microg intrathecal clonidine...
