Active clinical trials for "Premature Birth"

Detection of short cervix by transvaginal ultrasound and its evidence based management to prevent preterm birth .

Near-infrared spectroscopy (NIRS), is a technology that can provide continuous, non-invasive monitoring of oxygenation in tissue. The objective of this study is to obtain the cerebral regional oxygen saturation (cRSO2) in a preterm population that is born at altitude to determine if the range of "normal" values is different than those obtained at sea level.

We are attempting to improve the cerebral monitoring of extremely low gestational age (ELGA) infants, such that in the future, real-time monitoring will be possible, to aid clinicians in their management of these infants. We wish to establish a new NIRS device, diffuse correlation spectroscopy (DCS), as a safe, noninvasive and informative bedside tool for assessing and monitoring brain health in ELGA infants during the first few days of life. It is hoped that this method will provide detailed information on changes in oxygen consumption and metabolism, and cerebral perfusion. This technique will have wide applicability, but for this research study we wish to focus on the effect of blood flow instabilities, intermittent hypotension and hypoxic episodes, pressure passive CBF periods, and hypoperfusion on the preterm brain during the first days of life, and their relationship with incidence of intraventricular hemorrhage (IVH). We aim to recruit 100 premature infants to obtain data to: Test the feasibility of NIRS-DCS to monitor cerebral activity, perfusion and oxygen consumption in extremely premature infants during the first week of life. To assess if these baseline values are impacted by intermittent hypoxic episodes. To assess if cerebral blood flow disturbances correlate with incidence of intraventricular hemorrhage. Correlate the NIRS-DCS findings with clinical outcome at hospital discharge.

The investigators plan to use a new process to shorten the time of attaining full oral feeding in preterm infants less than 30 weeks gestational age.

To give strong recommendations on the efficacy and safety of vaginal progesterone versus cervical cerclage, we conduct this study to investigate the physical and mental development of children from vaginal progesterone versus cervical cerclage. Based on our research (Dang et al., 2019), the twin pregnancies with cervical lengths less than 38mm were randomly assigned to receive vaginal progesterone or cervical cerclage, which leads to the similarity in characteristics of these two groups. Hence, the result of analyzing these offsprings would be preciously valuable.

Prospective study comparing hemodynamic and respiratory changes and exercise capacity during Cardio-Pulmonary-Exercise-Testing (CPET) in 4 groups of infants; Three different groups of premature infants and term controls

Type of study: prospective descriptive monocentric study Population: 2 groups: -Exposed group: pregnant patient between 24AW+0day and 32AW+0day receiving magnesium sulfate for fetal neuroprotection in the doubt of premature delivery Control group: pregnant patient between 32AW+1day and 35AW+0day in the same context not requiring magnesium sulfate due to their gestationnal age. Criterion(s) of judgment: Appearance of a change in short-term variability after injection of magnesium sulfate in the exposed group compared to the control group. Schedule: Inclusion from February 20 to August 31, 2018 Expected results and prospects: The general impression during my semester at the Jeanne de Flandre maternity clinic in Lille was the variability improves after injection of the magnesium sulfate used in the premature infant as a neuroprotective. The investigators would like to proove that the use of magnesium sulfate as neuroprotective in premature fetuses would improve the fetal heart rate by increasing variability. In the literature there are numerous publications on the effects of magnesium sulfate used as tocolytic (higher doses) in the threats of premature labour, generally showing a variability and number accelerations decreases without increase the number of decelerations. Is this effect is the same as the doses used for fetal neuroprotection? Expected benefits of the research: Magnesium sulfate used on premature infants for fetal neuroprotection has an impact on fetal heart rate, including variability and number of accelerations.

Phototherapy is routinely used in neonatal intensive care units for the treatment of jaundice. Guidelines focus mainly on bilirubin serum levels to start the phototherapy. Only few data are available about clinical management of phototherapy devices and subsequently the impact on bilirubin serum decrease. Especially there are no strong recommendations about phototherapy duration, irradiance measurements, incubator temperature and humidity settings. Various factors can influence irradiance and thus the preterm infant bilirubin serum decrease. This study aims at evaluating the impact of an educational program on the use and efficacy of phototherapy in a neonatal intensive care unit.

The main purpose of this study is to identify and to determine the involvement of cardio-respiratory coordination mechanisms during SSC between the preterm infant and his (her) parent.

The aim of this study is to investigate the changes of amino acid metabolic profiles in different nutritional stages of preterm infants and determine the effects of nutritional intervention on the amino acid metabolic status of preterm infants.
