home uterine activity monitoring (huam) has demonstrated to be of great value for preventing preterm labor in recent years. in this research, a low cost monitoring device for non-invasive monitoring of the uterine activity in pregnant women is presented. the new device has been designed based on an inductive colpitz oscillator and vertical displacement of a ferrite core in a coil. the resulting...

Uterine contractions occur in runs of 1-3/hr throughout pregnancy from early in the second trimester until full term usually without consequence. Regular uterine contractions are essential in every case of preterm labor (PTL) resulting in preterm delivery at <37 weeks. It has been demonstrated that women are unable to accurately perceive the contractions associated with preterm labor while uter...

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: I...

OBJECTIVE To compare the Koala air-charged coupled catheter (Clinical Innovations, Inc., Murray, Utah) for monitoring intrauterine pressure (IUP) during active labor with an electronic pressure transducer-tip catheter, Intran Plus (Utah Medical Products, Midvale, Utah). STUDY DESIGN Simultaneous recordings with Koala and Intran catheters bound together at their tips were made in 18 term patie...

Introduction; Fetal monitoring of instantaneous heart rate (IHR) is one of major advances in recent perinatal medicine. It is widely accepted that changing pattern of fetal IHR associated with uterine contraction will reflect fetal well or ill being. Uterine contraction produces temporary hypoxia to the fetus and apnea does the same to the neorlate. Therefore we analysed changing patterns of ne...

Monitoring the progression of maternal uterine activity provides important prognostic information during pregnancy and parturition. Currently used methods for intrauterine pressure (IUP) measurement are unsuitable for long-term observation of uterine activity. The abdominally measured electrohysterogram (EHG) provides a non-invasive alternative to the existing methods for long-term ambulatory u...

background: there is much debate about effects of medicinal plants such as saffron (crocus sativus) on human health. women are highly involved in farming and processing of this plant. this study is aimed at evaluating the saffron impacts on miscarriage rate of female farmers working in saffron fields. methods: this was a prospective case-control study on pregnant female farmers during harvestin...

Background: Uterine bleeding is an important side effect of cesarean section which is due to non contractile uterine. The aim of this study was to compare the effect of 10% dextrose (IV infusion) and 40 IU/L oxytocin (IV infusion) on uterine contraction. Materials and Methods: This research was a double-blinded randomized clinical trial (RCT) study. 120 women were equally included in the tw...

At present, the most widespread method of monitoring of uterine contractions activity during pregnancy and labour is the external tocography. This mechanical method, however, has limited value resulting from its low accuracy and sensibility. Recent progress in new techniques of perinatal monitoring requires more precise method of monitoring uterine activity. The most promising seems to be the e...
