Filter by:Fetal heart rate (FHR) monitoring during labor aims to detect fetuses at risk of intrapartum hypoxia in order to accelerate their birth before the constitution of sequelae such as anoxic encephalopathy and cerebral palsy. But the positive predictive value of FHR monitoring is low, and many second-line tests have been proposed but none of them has been proven to be conclusive. Measure of placental elasticity and viscosity during labor could be a new second line test to complete the FHR monitoring. Several studies have shown that placental elasticity is increased in case of gestational diabetes, preeclampsia, or intrauterine growth restriction, but no study has focused on placental elasticity during labor. The investigators hypothesize that placental elasticity and viscosity could reflect the quality of maternal-fetal exchanges during labor, and could help to detect fetus at risk of intrapartum hypoxia. The first aim of this study is to describe the values of placental elasticity and viscosity during different points in the labor: beginning of the labor, beginning of the active phase of the first stage of labor, and passive phase of the second stage of labor. Secondary aims of this study are: to describe the values of placental elasticity and viscosity in case of oxytocin infusion, in case of abnormal FHR, and ex-vivo after placental expulsion. This unicentric observational prospective study will include 150 patients with singleton pregnancy, without pathology, with spontaneous labor at term.
Fetal cardiac monitoring is used during labor. Fetal decelerations may imply fetal hypoxia and distress. Brain activity monitoring is not used to evaluate fetal distress during labor. In this study the investigators intend to use an EEG based algorithm to evaluate and monitor fetal brain activity during the 2nd stage of labor.
The investigators want to compare the safety and efficacy between the combined spinal-epidural analgesia and epidural analgesia during labor.
Cardiotocography (CTG) is widely used during labour wards in industrialised countries and consists of fetal heart rate and uterine contraction monitoring. The main aim is to identify fetuses that are being poorly oxygenated during labour and require medical intervention to revert the situation or expedite delivery. The need for technical development of CTG is well-recognized, as some of the existing techniques are prone to signal loss and contamination from the maternal heart rate, while others are invasive and have established contra-indications. They also limit maternal mobilisation, contributing to maternal dissatisfaction, and possibly to adverse maternal and neonatal outcomes. New techniques for CTG acquisition will shortly be made available by a leading technological company, providing non-invasive monitoring and allowing full maternal mobilisation, and with the potential to change the way labour is conducted in high-resource countries. There is a need for a systematic evaluation of their clinical performance and benefit.
