Brief Summary:
The purpose of this study is to explore the perinatal risk factors of encephalopathy of prematurity and the morbidity of the following neurodevelopmental impairments in preterm infants with gestational age <32 weeks in China.

Condition or disease
Encephalopathy

Detailed Description:
Recent years have witnessed an increase in survival of very or extremely low birth weight infants, with a corresponding increase of attention to encephalopathy of prematurity (EOP) and the following neurological disorders. Studies suggested that hypoxic-ischemic injury and perinatal infection might be the two main risk factors of EOP, including white matter injury, neuronal-axonal diseases and cerebellar hemorrhage, which have a strong impact on neurological outcomes. Sequelae like cerebral palsy or mental retardation become a burden to both the family and society. Therefore, the risk factors of brain injury become the critical issue of both Obstetrics and Neonatology. More importantly, little is known about the morbidity of neurodevelopmental impairment and its risk factors in China. Thus, the aim of our study is to explore the perinatal risk factors of encephalopathy of prematurity and the morbidity of the following neurodevelopmental impairments in preterm infants with gestational age <32 weeks in China.

Study Type : Observational
Estimated Enrollment : 1500 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Multi-Center Cohort Study of Risk Factors and Outcomes of Encephalopathy of Prematurity in China
Study Start Date : April 2014
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2018

Group/Cohort
encephalopathy of prematurity
infants with encephalopathy of prematurity showed on MRI at term-equivalent age
no encephalopathy of prematurity
infants with no encephalopathy of prematurity showed on MRI at term-equivalent age



Primary Outcome Measures :
  1. developmental quotient (DQ) on the Gesell Developmental Schedules [ Time Frame: 2 years ]
    Result of gross motor, fine motor, language and social test. DQ = Development Age / Chronological Age X 100


Secondary Outcome Measures :
  1. brain injury showed on MRI [ Time Frame: 36-40 weeks' postmenstrual age or before discharge ]
    signal abnormality in white matter, grey matter or cerebellum injury; periventricular leukomalacia; intracranial hemorrhage

  2. morbidity of encephalopathy of prematurity [ Time Frame: 36-40 weeks' postmenstrual age or before discharge ]
    white matter injury, grey matter injury, cerebellum injury on MRI

  3. all cause mortality [ Time Frame: 2 years ]
  4. neurodevelopment sequelae [ Time Frame: 2 years ]
    including cerebral palsy, epilepsy, hearing loss, vision loss, etc.
