Altered mental status (AMS) is one of the most common reasons for inpatient neurology consultation. Non-convulsive status epilepticus (NCSE) is frequently on the differential diagnosis of the patient with AMS. NCSE becomes more refractory to treatment after one hour of seizure activity, making rapid identification and treatment of NCSE of great clinical importance. Currently, an electroencephalogram (EEG) technologist must be called in from home during non-workday hours in order to obtain a stat EEG. The investigators propose the time required for diagnosis of NCSE at Mayo Clinic can be significantly decreased with rapid placement of an EEG cap by the onsite neurology residents.
Controlled Hypothermia has become the standard of care for neonates with moderate to severe HIE. Ampicillin and aminoglycosides are drugs that are universally used for the treatment of suspected neonatal sepsis, which may or may not be responsible for the etiology of HIE. Currently, medication dosage regimens are not altered in the setting of CH. A better understanding of the effects of our interventions on this unique population may help us tailor our therapy to the specific circumstances of the patient
Excessive uterine activity may be one of several aetiological factors that contribute to depressed neurological function in the newborn. During labour, uterine contractions can compress the fetal cranium at pressures high enough to impair cerebral perfusion. Contraction rates greater than 7 in 15 minutes are associated with an increased risk of neonatal encephalopathy. The American Congress of Obstetricians and Gynecologists defines uterine tachysystole as more than 5 contractions in 10 minutes, averaged over a 30-minute window. By this definition, excessive uterine activity is common and, at best, a non-specific predictor of depressed neurological function in the newborn. There is a need for predictors of neonatal encephalopathy that are more specific and clinically applicable. Contraction and relaxation duration are two measures that closely reflect the proposed role of excessive uterine activity in the pathogenesis of neonatal encephalopathy. Prolonged contractions with short relaxation periods result in progressive reductions in fetal cerebral oxygenation. Shorter uterine contraction periods are associated with an increased risk of low umbilical cord potential of hydrogen (pH) values. Our primary aim is to measure parameters of uterine activity, for example relaxation and contraction duration, and determine their relationship with the risk of neonatal encephalopathy. We will also investigate how measures of uterine activity interact with other measures of labour and fetal well-being, including cervical dilation rates and fetal heart rate patterns. In babies with neonatal encephalopathy, we will investigate the relationship of uterine activity with electrophysiological, radiological and developmental outcomes. We will perform a retrospective case-control study of babies born in the Rotunda hospital from 2005 until the present. The assessor of the Cardiotocograph (CTG) recordings will be blind to the disease status of the infants. For each recording, every uterine contraction and rest interval will be measured. Summary variables created from these measures will be used to compare the case and control groups. The primary variable will be mean rest interval duration.
Ten infants undergoing therapeutic hypothermia for hypoxic-ischemic encephalopathy will be enrolled in a new protocol that will allow mothers to hold their infants during the hypothermia treatment period. This is a safety study that will assess whether or not there is an increase in adverse event frequency in infants that are held during hypothermia. Parents and NICU nurses will be given a questionnaire after holding is complete investigating their feelings on maternal-infant bonding and safety of the holding protocol.
Double-blind, placebo controlled Phase III trial of erythropoietin for hypoxic ischaemic encephalopathy in infants receiving hypothermia. The study aim is to determine whether Epo in conjunction with hypothermia in infants with moderate/severe hypoxic ischaemic encephalopathy (HIE) will improve neurodevelopmental outcomes at 2 years of age, without significant adverse effects, when compared to hypothermia alone.
Several studies have been showed that rifaximin can improve cognitive functions, driving simulator performance and health-related quality of life in patients with minimal hepatic encephalopathy. The aim of this prospective randomized open controlled study was to evaluate the efficacy and safety of rifaximin at different doses for the treatment of covert hepatic encephalopathy.
This is a Phase II multicenter placebo-controlled randomized, feasibility/safety trial. Infants >34 week gestational age with perinatal acidemia and mild neonatal encephalopathy on the modified Sarnat neurologic examination at less than six hours of age. Participants will be randomized to receive either one dose of Darbepoetin, or placebo within 24 hours of birth. Neurodevelopmental testing (Bayley (III or IV) and Gross Motor Function Assessment) will be performed at 24 months of age. Pharmacokinetics will be assessed on those infants that received Darbe.
The objective of the clinical investigation is to test whether intra-operative traction force feed back during vacuum extraction leads to a significant decrease in incidence of brain damage in neonates. By randomization, half of the vacuum extraction patients will be assigned to delivery using a new intelligent handle for vacuum extractions, and half will be assigned to conventional method without traction force measurement.
