Neonatal Hypoxic Ischemic Encephalopathy

The main purpose of this study will be to evaluate the prognostic value at 3 months of life of brain perfusion MRI determined by Arterial Spin Labeling technique in the first week of life of term newborns with hypoxic-ischemic encephalopathy requiring management in neonatal intensive care unit.

Severe Hypoxic Ischemic EncephalopathyModerate Hypoxic Ischemic Encephalopathy

The purpose of this study is to assess whether the addition of a drug such as Magnesium sulphate while providing therapeutic hypothermia (or cooling) to babies who are asphyxiated at birth provides additional benefit to the babies' survival and outcome compared to cooling alone.

Reno-protective Effect of Brain Cooling in Newborn With Hypoxia

Hypoxic Ischemic Encephalopathy

This study aims to determine the effect of therapeutic hypothermia on reducing AKI in term and late-preterm infants with hypoxic ischemic encephalopathy as estimated by measurment of serum(s) neutrophil gelatinase-associated lipocalin(NGAL) and serum (s) cystatin-C.

Study for the Improvement of Long-Term Outcome Prediction in Patients in Coma After Cardiac Arrest...

Anoxic-Ischemic Encephalopathy

The primary objective of HOPE is to improve the accuracy of outcome prediction in anoxic-ischemic encephalopathy following cardiac arrest by bringing under close scrutiny some of the existing methods used for this purpose (e.g. somato-sensory evoked potentials). HOPE is the first multicenter prospective cohort study on coma prognosis to control for the effect of a possible self-fulfilling prophecy at the ICU and to cover the acute and neurorehabilitation phases with a long-term follow-up longer than the usual three or six months.

NeoAdapt 3: Novel Biomarkers in the Evaluation of Neonatal Circulatory Insufficiency in Babies Suffering...

Circulatory Failure

1 in 1000 babies are born suffering from a lack of oxygen. This is known as hypoxic ischemic encephalopathy (HIE). Infants with this condition can suffer multiple organ problems. In particular it can affect how their hearts pump blood around their body thus leading to a poor blood supply to parts of their body such as the brain. This is known as circulatory failure and can contribute to poor long term outcomes such as cerebral palsy. To try and prevent brain damage these infants are treated with total body cooling, however this treatment can further effect how babies pump blood around the body, but also how drugs which may be used by in this condition are processed. In order to assess and treat this condition doctors need to be able to accurately measure the blood supply in an infant. However there is no agreement on how best to do this. This makes decisions about when to treat an infant difficult. Sometimes doctors may want to use drugs such as dobutamine or adrenaline but these drugs are unlicensed in babies. This study proposes to observe the way babies circulatory problems are treated in babies with HIE the in the first four days of life. In addition the study will look are two new measurements of a babies blood supply to see if they are a better measure of when an infant needs treatment. This will involve an ultrasound scan of the heart and measurement of the baby's oxygen levels from a probe placed on their hand. The study will also look at how the drug dobutamine is processed by babies. This will be done from two small extra blood tests. The aim of the study is to help clinicians refine the identification and treatment of circulatory failure in babies with HIE.

BiHiVE2 Study. The Investigation and Validation of Predictive Biomarkers in Hypoxic-ischaemic Encephalopathy....

Hypoxic Ischaemic Encephalopathy (HIE)Asphyxia

Despite recent advances in the care of mothers and newborn infants, many infants (approximately 20 per 1000 live births) continue to need resuscitation at birth. A proportion of these infants will have sustained significant injury through interruption of their blood and oxygen supply prior to delivery (perinatal asphyxia). In 2-3 babies per 1000 this will lead to brain swelling and the risk of long term brain injury called neonatal hypoxic-ischaemic encephalopathy (HIE). HIE remains a cause of neonatal death and long term disability. Early and accurate prediction of outcome would allow us to intervene during the window of the first 6 hours following birth, prior to secondary reperfusion and secondary brain injury. Estimating severity of injury can be difficult in newborn infants. Condition at birth does not predict neonatal, or longer term outcome. Biomarkers which could be measured at the time of birth and analysed at the bedside would offer these infants the best chance of timely and effective intervention. Through the BIHIVE study we have identified a number of predictive biomarkers in hypoxic-ischaemic encephalopathy. These markers are present in umbilical cord blood and have been identified through proteomic and metabolomic analysis of a stored biobank of samples from a recruited cohort of infants with perinatal asphyxia and hypoxic-ischaemic encephalopathy. We now wish to validate these biomarkers in an additional cohort, and will continue to explore new biomarkers in our stored biobank of umbilical cord samples. In addition we wish to assess our ability to predict neurodevelopmental and behavioural outcome in these infants. In this way we will determine the most robust biochemical and clinical markers for the prediction of early and medium term outcome in HIE. This study will establish the evidence base and validation of these biomarkers to the point where they can be developed into a bedside diagnostic algorithm which can be used in the labour ward to immediately identify those infants at risk of HIE in time to prevent secondary damage.

Out-of-hospital Cardiac Arrest (OHCA) Biomarkers

Neurological OutcomeCardiac Arrest10 more

Few early prognostic indicators are currently available for patients' families and clinicians following out of hospital cardiac arrest (OHCA), and blood biomarkers may be of prognostic value in these cases. Brain tissue is highly dependent upon aerobic respiration, and oxygen deprivation result in irreversible neuronal cell injury. Peptides released into the blood by injured neuronal cells can be measured to estimate degree of injury, and potentially predict long term neurological outcome.

Combined Intracerebral and Jugular Bulb Microdialysis

Subarachnoid HemorrhageHypoxia Ischemia3 more

The first aim of this study is to investigate the frequency and severity of a specific pathological metabolic pattern, mitochondrial dysfunction, of the brain in comatose patients under neurocritical care. This pattern is recognized as a complication after compromised blood flow to the brain and may be amenable to treatment. The other main aim of this study is to correlate patterns of metabolites between brain and jugular venous blood. It is probable but not proven that jugular venous microdialysis can mirror the global metabolic state of the brain.
