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.\n\nIn 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.\n\nThis 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failure in babies with HIE.", 'detailedDescription': 'The current definitions of neonatal shock/circulatory failure are outdated, inaccurate and it is not be appropriate to apply to infants suffering from hypoxic ischemic encephalopathy he purpose of the this research is to look at older than 33 weeks gestational age in order to fill the knowledge gap here and help in the development a new definition of neonatal circulatory failure.\n\nThe main research questions are:-\n\n1. To investigate new non-invasive methods of assessing an infants circulatory status in infants suffering from HIE.\n2. To gain initial data on how dobutamine is processed by babies when they are used for circulatory failure.\n3. To observe how physicians decide to treat circulatory failure in infants suffering from HIE.\n\nResearch has shown that there is up to a 14 fold difference in how doctors assess and treat circulatory failure. In infants suffering from hypoxic ischemic encephalopathy this is complicated further by the fact that treatment with total body cooling can interfere further with how the body pumps blood around the body. This is further complicated by the fact there is no agreed definition for circulatory failure in infants. By investigating new methods of assessing a babies circulatory status we intend to help create a new definition of circulatory failure which will in turn help doctors create further studies to identify infants with circulatory failure and find the best ways of treating this condition in babies. So far research in this area has been concentrated in babies born at less than 33 weeks gestation. We extend the knowledge in the area to infants older that 36 weeks gestation suffering from hypoxic ischemic encephalopathy.\n\nDobutamine is a drug that does not have a license for use in infants. In the future all new drugs will need to be studied in children before a license for them is given. In addition the European Community are encouraging that research is undertaken to look into the use of old drugs in which are used in babies. As mentioned previously there is very little data to show how dobutamine is handled by babies and contribute to new information on how this drug should be given safely.\n\nThis will be an observational pilot study, to gain novel values of SVC flows and pleth values in infants with HIE being treated with total body cooling. In addition this population will be observed with regard to which diagnostic measures that lead to treatment decisions, especially with regards to haemodynamic stability, and what the effect of those decisions are on the various diagnostic measures. Decision-making for their treatment will be based on clinical guidelines in at the Trevor Mann Baby Unit and clinician preference.\n\nThe assessment of SVC flow and PVI will only be done every 24 hours whist the infant is receiving total body cooling and once during the re-warming phase of their treatment.\n\nPrimary Outcome Measure Values for SVCF and PVI in neonates with HIE admitted for total body cooling derived from Echo-D and plethysmographic studies .\n\nObserved Clinical Outcome Measures\n\n* MRI appearances\n* Cranial US appearances\n* CFM appearances The MRI will be reported and scored according to a system described by Rutherford et al to aid predict long term outcome. This will be performed within the first two weeks post-total body cooling treatment which is in keeping with national and local guidance.\n\nThe analysis of the findings on cranial ultrasound scan will be interpreted in the light of a baseline scan, to be performed as soon as possible after birth on enrolment, to avoid ascribing the effect of antenatal insults to postnatal events.\n\nThose treated for HIE with total body cooling will have an additional daily neurological assessment during the cooling and re-warming phases of treatment that will be a graded according to criteria set out by Sarnat et al. This is routine in the treatment of this population of infants.\n\nCFM recordings will be made during the cooling treatment phase of an infant. This is a standard observation in children with HIE and is associated with long term outcomes for these infants. For the purposes of the study the CFM will be used at the discretion of the attending medical team. The analysis of the CFM will follow what was used in the Toby Trial and is described in detail elsewhere.\n\nTreatments for Circulatory Failure Infants will receive treatment according to the preference of the responsible physician. As is common practice, dobutamine, dopamine and/or other treatments (including other cardiovascular drugs and/or volume replacement therapy with normal saline) will be administered.\n\nDose of administration The dose of administration of dobutamine will be at the discretion of the responsible physician. We envisage that dobutamine will typically be started between 2.5 and 5 mcg/kg/min and increased in steps of 5 mcg/kg/min to a maximum of 20 mcg/kg/min with a given time frequency if no response is seen.\n\nAny changes to the treatment strategy will be documented by the responsible physician.\n\nCriteria for Up-Titration of Medication Dose escalation will be guided by clinical judgment. Clinicians will be asked to record the criteria they used in order to make this decision.\n\nCriteria for Down-Titration Dose reduction will be guided by clinical judgment. Clinicians will be asked to record the criteria they used in order to make this decision.\n\nFurther treatment If there is no response to dobutamine at 20 mcgg/k/min or the clinical response is considered by the attending physician to be inadequate, further treatment will be at the discretion of the attending physician who will be asked to record the reasons for the change in treatment strategy as well as the additional treatment that is given to the patient.\n\nConcomitant therapy There will be no per-protocol concomitant medication or treatment. Accordingly, other important co-interventions will follow specific centre protocols and will be recorded in the case record form.\n\nPHARMACOKINETICS (PK) SUB-STUDY\n\nAim of the PK sub-studies The aim of the sub-study is to give preliminary information in order to try and construct a population PK model. Given the uncertainties regarding the PK of dobutamine in infants receiving total body cooling we shall assess its elimination half life. This is defined as the amount of time for the quantity of a concentration to fall by half.\n\nHalf-life sub-study We will perform a preliminary study on all the infants included in NeoAdapt 3 that receive dobutamine as treatment for haemodynamic insufficiency. Two blood samples, of 400 μl each, will be obtained from each of these patients. The first sample will be drawn after the end of the infusion, at the time when dobutamine ceases reaching the systemic circulation of the neonate, defined as time end (te).\n\nThe second sample will be taken at different study time points after the end of infusion:\n\n* 5 min after te\n* 15 min after te\n* 45 min after te\n* 2 hours after te\n* 6 hours after te Two infants will be allocated to each time point. Sampling times will be assigned randomly to the patients.\n\nPlasma samples will be sent to the laboratory for the quantification of dobutamine.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '3 Days', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Infants older than 36 weeks gestational age suffering from hypoxic ischemic encephalopathy receiving total body cooling', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Infants admitted to the NICU with HIE for total body cooling therapy\n* Postnatal age \\<72 hours\n* Parental informed consent\n\nExclusion Criteria:\n\n* Non-viability\n* Congenital hydrops or malformations likely to affect cardiovascular adaptation\n* Surgery planned within 72 hours of birth\n* Chromosomal anomalies\n* Informed consent form (ICF) not signed'}, 'identificationModule': {'nctId': 'NCT02051894', 'briefTitle': 'NeoAdapt 3: Novel Biomarkers in the Evaluation of Neonatal Circulatory Insufficiency in Babies Suffering From Hypoxic Ischemic Encephalopathy', 'organization': {'class': 'OTHER', 'fullName': 'Brighton and Sussex University Hospitals NHS Trust'}, 'officialTitle': 'NeoAdapt 3: An Observational Study Investigating Novel Biomarkers in the Evaluation and Treatment of Neonatal Circulatory Insufficiency in Infants Suffering From Hypoxic Ischemic Encephalopathy.', 'orgStudyIdInfo': {'id': 'IRAS: 145271'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'HIE Group', 'interventionNames': ['Drug: Dobutamine']}], 'interventions': [{'name': 'Dobutamine', 'type': 'DRUG', 'description': 'Infants will receive treatment according to the preference of the responsible physician.
