BACKGROUND Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes. METHODS ...

OBJECTIVE We aimed to evaluate the performance of a non-invasive EMG electrical uterine monitor (EUM) versus tocodynamometry (TOCO) by comparing both to internal uterine pressure catheter (IUPC). STUDY DESIGN Prospective observational trial. Uterine activity was recorded continuously and simultaneously, in women during active term labor, with TOCO, EUM and IUPC. Uterine activity tracings were...

Uterine contractions play a very important role in the smooth delivery process. However, some mothers experience problems uterine which will result length of labor So cases need induction assistance. Advances medical science terms acupressure and rebozzo have become several solutions for certain treatments without involving chemistry it. This study aims to be applied directly this case help red...

Uterine contractions were monitored in 54 patients in whom severe abruptio placentae had caused intra-uterine death of the fetus. The frequency at the beginning of monitoring ranged from 2 to 14 contractions in 10 minutes, with a mean of 8,4. Only 4 patients had 4 or fewer contractions in the first 10 minutes of monitoring. No change in contraction frequency was observed during the course of la...

Although premature separation of normally implanted placenta is considered the most serious complication of pregnancy, knowledge of uterine behaviour during this con­dition is meager, on the basis of electronic recording of intra-uterine pressure two type of contraction pattern has been identified.  In type I uterine tonus has values below 30mmHg  with a frequency of 4-9 contractions per 10 m...

Electronic foetal heart-rate monitoring In current practice, electronic foetal heart-rate monitoring is performed by either the internal or the external method. With the internal method, an ECG electrode is applied directly to the foetus, and the monitor separates the foetal electrocardiogram from the maternal, amplifies the foetal signal and measures the intervals between consecutive foetal he...

preterm contraction of uterus is a main cause of miscarriages and preterm labour. euphorbia known as ferphion in iranian traditional medicine texts like al-hawi, is reported for prevention of preterm labour. therefore, the objective of this research was to investigate the effect of euphorbia spinidens bornm. ex prokh. on motility of rat uterus. uterine horns were isolated form non-pregnant fema...

Endocrine-disrupting chemicals (EDCs) are exogenous substances that alter the structure or function of the endocrine system. 4-Tert-octylphenol (OP) is one of the most representative EDCs and has estrogenic effects. In this study, we examined the effects of ethinyl estradiol (EE) and OP on the pituitary gland, placenta, and uterus of pregnant rats. Expression levels of human chorionic gonadotro...

In the present study, we compared rat uterine contractility and myometrial inositol phosphate (InsP) production in response to activation of muscarinic and oxytocin receptors during pregnancy and at term. The level of myometrial phospholipase (PL) C was also determined by Western blotting at different stages of pregnancy and following administration of oestradiol, progesterone or vehicle. The r...
