BACKGROUND: Resuscitation following birth asphyxia reduces mortality, but may be argued to increase risk for neurodevelopmental disability in survivors. AIMS: To test the hypothesis that development of infants who received resuscitation following birth asphyxia is not significantly different through 36months of age from infants who had healthy births. STUDY DESIGN: Prospective observational cohort design comparing infants exposed to birth asphyxia with resuscitation or healthy birth. SUBJECTS: A random sample of infants with birth asphyxia who received bag-and-mask resuscitation was selected from birth records in selected communities in 3 countries. EXCLUSION CRITERIA: birth weight<1500g, severely abnormal neurological examination at 7days, mother<15years, unable to participate, or not expected to remain in the target area. A random sample of healthy-birth infants (no resuscitation, normal neurological exam) was also selected. Eligible=438, consented=407, and ≥1 valid developmental assessment during the first 36months=376. OUTCOME MEASURE(S): Bayley Scales of Infant Development-II Mental (MDI) and Psychomotor (PDI) Development Index. RESULTS: Trajectories of MDI (p=.069) and PDI (p=.143) over 3 yearly assessments did not differ between children with birth asphyxia and healthy-birth children. Rather there was a trend for birth asphyxia children to improve more than healthy-birth children. CONCLUSIONS: The large majority of infants who are treated with resuscitation and survived birth asphyxia can be expected to evidence normal development at least until age 3. The risk for neurodevelopmental disability should not justify the restriction of effective therapies for birth asphyxia.

OBJECTIVE: The Bayley Scales of Infant Development (BSID) is the most used diagnostic tool to identify neurodevelopmental disorders in children under age 3 but is challenging to use in low-resource countries. The Ages and Stages Questionnaire (ASQ) is an easy-to-use, low-cost clinical tool completed by parents/caregivers that screens children for developmental delay. The objective was to determine the performance of ASQ as a screening tool for neurodevelopmental impairment when compared with BSID second edition (BSID-II) for the diagnosis of moderate-to-severe neurodevelopmental impairment among infants at 12 and 18 months of age in low-resource countries. METHODS: Study participants were recruited as part of the First Bites Complementary Feeding trial from the Democratic Republic of Congo, Zambia, Guatemala and Pakistan between October 2008 and January 2011. Study participants underwent neurodevelopmental assessment by trained personnel using the ASQ and BSID-II at 12 and 18 months of age. RESULTS: Data on both ASQ and BSID-II assessments of 1034 infants were analysed. Four of five ASQ domains had specificities greater than 90% for severe neurodevelopmental delay at 18 months of age. Sensitivities ranged from 23% to 62%. The correlations between ASQ communications subscale and BSID-II Mental Development Index (MDI) (r=0.38) and between ASQ gross motor subscale and BSID-II Psychomotor Development Index (PDI) (r=0.33) were the strongest correlations found. CONCLUSION: At 18 months, ASQ had high specificity but moderate-to-low sensitivity for BSID-II MDI and/or PDI <70. ASQ, when administered by trained healthcare workers, may be a useful screening tool to detect severe disability in infants from rural low-income to middle-income settings.

Randomized trial of early developmental intervention on outcomes in children after birth asphyxia in developing countries.

OBJECTIVE: To determine if early developmental intervention (EDI) improves developmental abilities in resuscitated children. STUDY DESIGN: This was a parallel group, randomized controlled trial of infants unresponsive to stimulation who received bag and mask ventilation as part of their resuscitation at birth and infants who did not require any resuscitation born in rural communities in India, Pakistan, and Zambia. Intervention infants received a parent-implemented EDI delivered with home visits by parent trainers every other week for 3 years starting the first month after birth. Parents in both intervention and control groups received health and safety counseling during home visits on the same schedule. The main outcome measure was the Mental Development Index (MDI) of the Bayley Scales of Infant Development, 2nd edition, assessed at 36 months by evaluators unaware of treatment group and resuscitation history. RESULTS: MDI was higher in the EDI (102.6 ± 9.8) compared with the control resuscitated children (98.0 ± 14.6, 1-sided P = .0202), but there was no difference between groups in the nonresuscitated children (100.1 ± 10.7 vs 97.7 ± 10.4, P = .1392). The Psychomotor Development Index was higher in the EDI group for both the resuscitated (P = .0430) and nonresuscitated children (P = .0164). CONCLUSIONS: This trial of home-based, parent provided EDI in children resuscitated at birth provides evidence of treatment benefits on cognitive and psychomotor outcomes. MDI and Psychomotor Development Index scores of both nonresuscitated and resuscitated infants were within normal range, independent of early intervention.
