Filter by:This study is a randomized, placebo-controlled, clinical trial to evaluate whether induced whole-body hypothermia initiated between 6-24 hours of age and continued for 96 hours in infants ≥ 36 weeks gestational age with hypoxic-ischemic encephalopathy will reduce the incidence of death or disability at 18-22 months of age. The study will enroll 168 infants with signs of hypoxic-ischemic encephalopathy at 16 NICHD Neonatal Research Network sites, and randomly assign them to either receive hypothermia or participate in a non-cooled control group.
This is a pilot study to test feasibility of collection, preparation and infusion of a baby's own (autologous)umbilical cord blood in the first 14 days after birth if the baby is born with signs of brain injury.
This is a research study of head cooling. Its goal is to determine whether cooling babies' heads can reduce or prevent brain damage that may have resulted from temporarily reduced oxygen supply to the brain. In this study, half of the babies (selected at random) will have a special cooling cap with circulating water placed on their head for 72 hours to lower the temperature of their brain. The rest of the baby's body will be maintained at a defined temperature by a standard overhead radiant heater. The study protocol includes the taking and analysis of blood samples, performance of brain wave tests, imaging of the brain by ultrasound, and other tests as clinically indicated. Neurodevelopmental outcome will also be assessed at 18 months of age.
The investigators propose to compare the proteomic analysis of umbilical venous blood from neonates with brain injury to gestational age matched noninjured controls. After delivery an umbilical arterial gas and a 10 ml umbilical venous sample are obtained, then the remainder of the cord blood is discarded. The investigators plan to use this cord blood that would otherwise be discarded to perform our proteomic analysis. The investigators will use up to 20 ml of cord blood per delivery. This will be a 5 year study during which time the investigators hope to analyze 450 infants at Johns Hopkins Hospital and Bayview Medical Center. The investigators will obtain an umbilical venous sample from infants born at < 34 weeks gestation. For infants born at > 34 weeks the investigators will obtain an umbilical venous sample for any infant suspected to be at risk for neurologic injury by having a diagnosis of chorioamnionitis during labor, nonreassuring fetal heart rate tracing at the time of delivery, or a 5 minute Apgar < 7. For the infants born at < 34 weeks the brain injured infants will be compared to gestational age matched controls without brain injury. For the infants born at > 34 weeks, each infant later confirmed to have neurologic morbidity will be compared to a gestational age matched noninjured control. The investigators hope to use proteomic analysis to determine if there are measurable differences in protein expression between the 2 groups.
Asphyxia is a leading cause of neonatal death in Zambia. This study will be conducted in two cities in Zambia to determine if the combined Neonatal Resuscitation Program/Essential Newborn Care Program compared to the new World Health Organization (W.H.O.) basic perinatal care education of health care providers (Essential Newborn Care Program) results in reduced mortality due to perinatal asphyxia.
This study examines the potential benefits of a home stimulation program to treat infants who have suffered from brain asphyxiation (lack of oxygen). The program involves one year of stimulatory activities. Progress will be evaluated through neurological and behavioral exams.
This large multicenter trial tested whether cerebral cooling initiated within 6 hours of birth and continued for 72 hours would reduce the risk of death and moderate to severe neurodevelopmental injury at 18-22 months corrected age. Infants at least 36 weeks gestation with an abnormal blood gas within 1 hour of birth, or a history of an acute perinatal event and a 10-min Apgar score <5, or continued need for ventilation were screened. Following a neurological exam, those with moderate to severe encephalopathy were randomized to a 72-hour period of total body cooling (cooling blanket, followed by slow re-warming). The study was conducted in two phases: Phase I (20 infants) were examined for the safety of an esophageal temperature of 34-35 C; Phase II (main trial, 200 infants) were evaluated for the safety and efficacy of an esophageal temperature of 33-34 C. Cardio-respiratory, electroencephalograms (EEGs), renal, metabolic, and hematologic status, and esophageal and abdominal skin temperature were monitored during the 72 hours of intervention. Surviving children were given neurodevelopmental examinations at 18-22 months corrected age and again at school age (6-7 years of age).
