About this trial

To determine effectiveness of therapy to improve neurodevelopmental outcomes in infants with mild HIE. To determine the adverse effects of Therapeutic Hypothermia (TH) in mild HIE on the neonate and his/her family. Determine heterogeneity of the treatment effect across key subgroups obtained in the first 6 hours after birth prior to the decision to initiate therapy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Neonates born at ≥ 36 0/7 weeks

Mild Encephalopathy on neonatal neurologic exam within 6 hours after birth: defined as presence of at least 2 signs of mild, moderate, or severe encephalopathy with no more than 2 signs in the moderate or severe category.

pH ≤ 7.00 in any cord or first infant gas (arterial, venous, or capillary) within ≤ 60 min OR base deficit ≥ 16 in any cord or first infant gas (arterial, venous or capillary) within ≤ 60 min

If pH is between 7.01 and 7.15, OR base deficit is between 10 and 15.9 mmol/liter, OR blood gas is not available, an acute perinatal event is an additional criteria required (see below definition)

Disqualifiers

Gestational age at birth < 36 0/7 weeks

Birth weight < 1800gm

Head circumference <30cm

Congenital or chromosomal anomaly associated with abnormal neurodevelopment or death

Trial population

Term infants ≥ 36 weeks' gestation with evidence of both perinatal event fetal acidosis and encephalopathy on exam.

Time perspective

Prospective

Treatments tested in this trial

  • Normothermia

    Procedure/Surgery

  • Whole body therapeutic hypothermia

    Procedure/Surgery

    Whole-body therapeutic hypothermia (33.5°C ± 0.5°C) for 72 hours began by 6 hours of age for neonates with mild encephalopathy per site standard of care practice.

Trial outcomes

Primary outcomes

1

Effectiveness of normothermia in infants as measured by Composite Bayley IV score

Effectiveness of normothermia in infants is measured by Composite Bayley IV score scale, which is. an extensive formal developmental assessment tool for diagnosing developmental delays in early childhood. Possible scores range from 55- 120 where lower scores indicate worse outcome.

Time frame
22-26 months of age.

Secondary outcomes

1

Adverse events SAE

Safety will be measured by the presence or absence of a serious adverse event (SAE) at discharge.

Time frame
Discharge (approximately 7 days)
2

Parent-Infant stress and bonding as measured by MIBS

Parent-Infant stress and bonding is measured by Mother-to-infant bonding (MIBS) scale, which is a validated questionnaire with good psychometric properties that assesses the mother's feelings towards infant (bondedness) from birth to 4 months. Possible scores range from 0-3, where 0 indicates "not at all" and 3, "very much".

Time frame
3-4 months
3

Parent-Infant stress and bonding as measured by IBQR

Parent-Infant stress and bonding is measured by Infant Behavior Questionnaire-Revised (IBQR) which measures differences in reactivity and regulation, and the structure of infant temperament and its relation to parental family functioning. Item scores were summed according to IBQR scoring rules to create scores on the 14 scales, with higher scores indicating greater levels of that temperament dimension.

Time frame
3-4 months
4

Parent-Infant stress and bonding as measured by PSI

Parent-Infant stress and bonding is measured by Parenting Stress Index (PSI) which is an abbreviated version of the full-length test with 36 items in three domains (Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child) that combine to form a Total Stress scale, which helps identify families that are most in need of support services. In general, items are scored using the following 5-point scale: 1) SA (Strongly Agree), 2) A (Agree), 3) NS (Not Sure), 4) D (Disagree), 5) SD (Strongly Disagree). Responses to both the overall stress score and the three subscales are summed to generate representative scores, resulting the total stress score, perceptions of child behavioral problems, parenting distress, and parent-child dysfunctional interactions.

Time frame
3-4 months

Other outcomes

1

Infant neurological integrity as measured with HNNE

Infant neurological integrity is measured with HNNE (Hammersmith Neonatal Neurological Exams), which is used to assess tone, spontaneous movements, reflexes, and visual and auditory attention allowing for a continuum of assessment from birth to 2 years. The maximum score for any one item is a score of 3 and the minimum is a score of 0. A subscore can be given for each section and the overall global score can be calculated by summing up all 26 items (range: 0-78), with higher scores indicating better neurological performance. The maximum global score is 78.

2

Infant neurological integrity as measured with HINE

Infant neurological integrity is measured with HINE (Hammersmith Infant Neurological Exams), which is used to assess tone, spontaneous movements, reflexes, and visual and auditory attention allowing for a continuum of assessment from birth to 2 years. The maximum score for any one item is a score of 3 and the minimum is a score of 0. A subscore can be given for each section and the overall global score can be calculated by summing up all 26 items (range: 0-78), with higher scores indicating better neurological performance. The maximum global score is 78.

Time frame
3 - 4 months

Behavioral tendency CBCL

The Child Behavior Checklist-parent report (CBCL) will provide a profile of behavior and social functioning validated in relation to age and gender.

Time frame
22-26 months of age.
