O'Connell M P - - 2001
OBJECTIVE: To review obstetric practice in a single maternity hospital with respect to the assisted vaginal delivery rate. METHOD: A retrospective analysis of the hospital statistics, labor ward records, casenotes and management protocols with respect to the second stage of labor was performed in a single maternity unit in the ...
Fortunato S J - - 2001
OBJECTIVE: On a clinical level, the etiologies associated with premature rupture of the membranes and preterm labor are virtually identical, though these conditions end in distinctly different events. This study was designed to determine differences between preterm labor and preterm premature rupture of membranes by using molecular markers of extracellular ...
Crane J M - - 2001
OBJECTIVE: To estimate the incidence and timing of excessive uterine activity accompanying induction of labor with misoprostol using different routes (oral or vaginal) and forms (intact tablet or crushed) and to compare these with dinoprostone gel, oxytocin, and spontaneous labor. METHODS: This retrospective cohort study included 519 women at term ...
Sims E J - - 2001
OBJECTIVE: Our purpose was to determine the impact of labor induction on both the success and safety of a trial of labor in women who are candidates for vaginal birth after cesarean. STUDY DESIGN: We performed a prospective observational analysis of 505 women consecutively presenting for delivery with a prior ...

OBJECTIVE: Numerous studies have assessed the significance of meconium-stained amniotic fluid (MSAF) at term. However, to date, there has been very little documentation on the incidence and significance of meconium in the preterm population. Our objective was to define the incidence of MSAF in patients delivering prematurely (<37 weeks) and ...

Ransjö-Arvidson A B - - 2001
BACKGROUND: Newborns not exposed to analgesia, when placed on the mother's chest, exhibit an inborn prefeeding behavior. This study was performed to assess the effects of different types of analgesia during labor on the development of spontaneous breastfeeding movements, crying behavior, and skin temperature during the first hours of life ...

OBJECTIVE: The hypothesis of this prospective study is that intrapartum vibroacoustic stimulation (VAS) is an effective predictor of fetal acidosis during labor. Various clinical conditions, such as term versus preterm gestation, first stage versus second stage of labor, and fetal heart rate (FHR) variable decelerations versus late decelerations will be ...
Kavanagh J - - 2001
Dilatation and effacement of the cervix are not only a result of uterine contractions, but are also dependent upon ripening processes within the cervix. The cervix is a fibrous organ composed principally of hyaluronic acid, collagen and proteoglycan. Hyaluronic acid increases as pregnancy progresses, increases markedly after the onset of ...
Hayashi R H - - 2000
The clinician is faced with many dilemmas in the diagnosis of preterm labor. The tools at hand (no pun intended) yield subjective information and it is difficult to distinguish true labor from false labor. Because preterm labor is multifactorial in cause and can occur in primiparas, estimating risk for the ...
Ramsey P S - - 2000
Labor induction has become commonplace in modern obstetrics. The increasing rate of labor induction has probably played a role in the increased rate of cesarean delivery observed in the United States during the past few decades. Clearly, the favorability of the cervix has a substantial impact on the potential success ...
Sizer A R - - 2000
OBJECTIVE: To determine factors associated with term delivery in the occipitoposterior position and examine obstetric outcomes from that delivery position in nulliparas. METHODS: We did a retrospective analysis of population-based data of 16,781 nulliparas who delivered at term (37-42 weeks) with singleton, cephalic presentations. Factors examined for possible association with ...

Using a multidimensional approach to measure stress, this study prospectively examined the influence of maternal stress, social support and coping styles on labor/delivery complications and infant birth weight. Beginning in the third month of pregnancy, stress was assessed monthly. In each trimester, data on social support, coping strategies, lifestyle behaviors ...
Connolly T P - - 2000
A retrospective analysis of 1- and 5-minute Apgar scores of patients at term gestation (37 to 42 weeks) with evidence of clinical intra-amniotic infection and meconium-stained amniotic fluid was performed. The patients were selected from the labor and delivery records of two Detroit hospitals during the study period from January ...
Impey L - - 2000
OBJECTIVE: Active management has been shown to shorten the length of labor and reduce the incidence of prolonged labor. We examined the influence of this protocol on the rate of cervical dilatation by calculating a mean partogram to explain how this acceleration is achieved. STUDY DESIGN: We retrospectively analyzed partograms ...

Preterm labor (PTL) is defined as uterine irritability accompanied by cervical dilation and/or effecement that occurs before 37 weeks gestation. In most cases, PTL becomes preterm delivery (PTD), accounting for 8% to 10% of births in the United States. Fetuses born before 37 weeks' gestation are at risk for a ...

PROBLEM: Clinically useful tests for the prediction and diagnosis of preterm labor and delivery remain to be established. We have hypothesized that soluble intercellular adhesion molecule-1 (sICAM-1) in the cervicovaginal fluid of women with preterm labor may be a useful diagnostic tool. METHOD OF STUDY: The cervicovaginal fluid of 103 ...

Myometrial contractions of labor result from an increase in myometrial activation and stimulation. Activation develops through the expression of contraction associated proteins (CAPs), including oxytocin receptors (OTR), connexin-43 (Cx-43), and prostaglandin F2 alpha, receptors (FP). Stimulation involves increases in contractile agonists including prostaglandin E2 (PGE2) and prostaglandin F2 alpha. (PGF2 ...

Methods to prevent perineal trauma during childbirth include avoiding episiotomy and forceps delivery and slowing delivery of the head to allow the perineum time to stretch. Each intervention can lengthen the second stage of labor and change the biophysical stresses on infants and the pelvic floor. Available evidence supports the ...
Gunalp S - - 2000
BACKGROUND: Misoprostol was reported to be an effective agent for cervical ripening and induction of labor. Our purpose was to evaluate whether vaginal pH affected the efficacy of misoprostol for induction of labor. METHODS: The vaginal pH of 103 women admitted for induction of labor were measured. According to the ...

Renal tubular acidosis in pregnancy is a very rare disorder. Most cases are either inherited or secondary to maternal disease or ingestion of toxic chemicals. We report a 22-year-old woman, previously healthy, who presented at 27 weeks of gestation with preterm labor. Investigation revealed renal tubular acidosis with no obvious ...
Cuervo L G - - 2000
The use of enemas during labor usually depends on the preference of the attending physician and available resources. However enemas cause discomfort in women and increase the costs of delivery. The objective of this review was to assess the effects of enemas during the first stage of labor on infection ...

Ogawa M - - 1999
BACKGROUND: Emergent cervical cerclage is often unsuccessful in patients with severely protruding fetal membranes for the following reasons: (1) difficulty in pushing the bulging membranes into the cervix; (2) risk of premature rupture of membranes during the operative procedures; and (3) displacement of the cerclage tape by the shortened cervix. ...

Kelly F W - - 1999
This article reviews a number of nonevidenced-based studies that have been conducted on the different physical positions of labor and delivery. A review of the literature disclosed that the traditional supine position appeared to be associated with a prolonged second stage of labor and persistence of occiput posterior presentations. However, ...
Tebes C C - - 1999
An infant born in a compound presentation had ischemic forearm necrosis requiring amputation. Bilateral renal vein thrombosis predating labor and delivery was also diagnosed. The possibility of congenital ischemic necrosis in an extremity should not affect the obstetrical management of compound presentation, but if this complication occurs a search for ...
