...Samuel Lurie; Eran Weiner; Abraham Golan; Oscar Sadan Aims: To establish leukocyte count and differential percentiles in healthy singleton term laboring women during spontaneous normal vaginal labor following an uncomplicated pregnancy. Methods: An analysis of the records of all women (n = 762) who...

... widely used model. Materials and Methods: Women attempting trial of labor after cesarean delivery (TOLAC) at our institution from January 1, 2000 through May 30, 2010 were evaluated for inclusion. Demographic and clinical data were collected. Associations of these characteristics with VBAC were evaluated...

The computerized analysis...

...Y. Ogawa; L. Herod; J.T. Lanman A soya bean oil containing predominantly phospholipids (SBP) has been known to sensitize the pregnant rabbit uterus to oxytocin, permitting premature induction of labor. We are attempting to identify the active component. Lipid class analyses of SBP revealed...

...Y. Lefèbvre; A. Chapdelaine; E. Bolté Maternal and cord plasma dehydroepiandrosterone sulfate (DHAS) and cortisol were measured before cesarean section, during syntocinon induced labor, and at delivery after spontaneous or induced labor. The mean maternal plasma DHAS was significantly lower...

...M.R. Neuman; Judith A. Jordan; J.F. Roux; J.D. Knoke The accuracy of transvaginal intrauterine pressure measurements was determined in 21 subjects in labor, 12 of which were monitored with two transcervical intrauterine catheters and one miniature intrauterine pressure transducer, and 9 subjects...

... of three samples had no difference between the induced labor group and the spontaneous onset of labor group regardless of delivery mode. In spontaneous vaginal delivery the cortisol levels of three individual samples were significantly higher in primipara than in multipara. The positive correlations were...

... levels in the course of labour as early as 90 min ante partum and reached values of 0–3 mm Hg at birth. In 9 of these 10 cases a tcpO 2 ‘zero line’ could be monitored in the last 2–90 min prior to birth. The tcpO 2 did not correlate to either the pO 2 of the arterialised fetal scalp blood or to the pO 2...

Genazzani; Felice Petraglia; Generoso Di Meo; Vita Santoro; Fabio Facchinetti; Alberto Segre The continuous and progressive rise of Β-endorphin (B-EP), Β-lipotropin (B-LPH) and cortisol plasma levels during labor in term-pregnant women represents one of the most relevant maternal hormonal...

... of amniotic fluid embolism in maternal mortality as a whole increased from 1.2 to 16.5% during this period. Predisposing factors identified were gemini/polydyramnios, abruptio placentae, hypertonic labor, rupture of the birth canal, macrosomia, and obstetrical interventions such as administration of oxytocin...

Lower levels of total zinc and of zinc derived from both carbonic...

...Andrea R. Genazzani; Felice Petraglia; Fabio Facchinetti; Paolo A. Galli; Annibale Volpe Β-Endorphin (Β-EP), Β-lipotropin (Β-LPH) and cortisol plasma levels were measured during labor in 18 pregnant women. In 7 cases labor progressed spontaneously and in 11 cases oxytocin (5 mlU/min...

No obvious difference in nerve density was observed between nonpregnant, early pregnant and term pregnant women, and still during labor the innervation appeared morphologically preserved. It is suggested that the segmental difference in innervation of the human uterus (corpus versus...

...G. Ohel; A. Simon; Y. Beyth; E. Sadovsky The fetal heart rate (FHR) response to a vibroacoustic stimulation was studied in 100 women during active labor. Three types of FHR responses were noted: acceleration, tachycardia of duration longer than 2 min, and combined acceleration-deceleration response...

...Leif Svenningsen; Øystein Jensen The article describes a novel method for the objective measurement of compression forces to which the fetal head is exposed during labor. This involves the placement of a transducer, housed in a silicone rubber and brass casing (18 mm diameter, 6.5 mm thick), over...
