These observations while supporting the inhibitory effects of BPA on cultured uterine cells in vitro [9] further, demonstrate the decreased responsiveness of uterine contractions to acetylcholine after exposure to BPA.
To improve the result we introduced a new condition that removes some of the false positive and false negative recordings, which consists in the presence of late and prolonged decelerations associated with uterine contractions in the FHR tracing.
The aim of this work was therefore to develop a tool that would provide automatic segmentation of EHG recordings while distinguishing between uterine contractions and artifacts, to promote the future clinical use of this non-invasive technique for dynamic uterine monitoring and predicting premature births.
In the majority of the in vitro studies (11 out of 13 studies), the inhibitory effects of herbal medicines on uterine contractions were investigated.
[5] included women with singleton and twin pregnancies presenting with regular uterine contractions with dilatation or cervical change between 23 and 33 weeks of gestation.
In that we consider of giving perioperative syntocinon infusion 2 units [12,13] in 100 ml NS (before the uterine incision [14] and delivery of the baby) as a priming technique to augment uterine contractions [15] and from our observation it is found to be more beneficial in maintaining haemodynamic stability [16] without much usage of inj.
Activating this receptor causes vasoconstriction, platelet activation, and uterine contraction.
The variable in this study are time for induction (time recorded when 1st dose of tablet placed vaginally till the onset of regular painful uterine contractions), duration of labour (time from regular uterine contractions till delivery), mode of delivery, complications including uterine hyperstimulation (more than 5 contractions in 10 mins or contraction lasting more than 2mins) fetal distress by CTG and fetal heart rate monitoring and in the end fetal outcome in terms of APGAR score at 0, 5 and 10mins and admission in NICU.
The first stage is the period from the beginning of regular uterine contractions until full cervical dilation; the second stage is from full cervical dilation to the birth of a neonate; and the third stage is from the birth to completion of expulsion of the umbilical cord, placenta and foetal membrane.
Although the extracts were used for KCl- and oxytocin- induced uterine contraction, however, the comparison of PGE antispasmodic effect on these spasmogens shows that the effects of the extracts on oxytocin-induced contractions is more potent than on KCl-induced contraction.
