Auditory brain stem evoked response (ABR) testing was performed on 50 very low birthweight infants in an effort to assess the effects of multiple neonatal risk factors on auditory function. The results suggested that no single risk factor was predictive of ABR abnormality while combined risk factors were shown to be very predictive.

Middle-school-age outcomes in children with very low birthweight.

Most previous studies of children with birthweight <750 g have focused on early childhood sequelae. To evaluate later outcomes, a regional sample of 60 <750-g birthweight children was compared at middle school age (M = 11 years) to 55 children with birthweight 750-1,499 g and 49 term controls. The groups were matched on age, gender, and demographic variables at the time of an early-school-age assessment (mean age 7 years). The <750-g birthweight group fared less well at middle school age than the term group on measures of cognitive function, achievement, behavior, and academic performance. In many instances, outcomes were less favorable for the <750-g children than for the 750 to 1,499-g group. Children in the <750-g group who were free of neurosensory disorders and global cognitive impairment performed more poorly on several tests than their term counterparts. Group differences in this subsample on tests of motor skills, math, and the ability to copy and recall a complex drawing remained significant even after controlling for IQ. Disparities between the <750-g and term groups increased with age for some measures. Despite favorable outcomes for many children in the <750-g group, this population is at risk for long-term developmental problems.

Pneumopericardium in very low birth weight infants.

The objective of this study was to describe the incidence, neonatal correlates, and outcome of pneumopericardium (PPC) in very low birth weight (VLBW) < or = 1.5 kg infants. Forty-seven VLBW infants with a PPC, born during 1977 to 1989, were compared with a cohort of 1302 ventilated VLBW infants. PPC developed in 2% of 2389 VLBW infants and 3.5% of 1349 ventilated infants. The mean birth weight (1008 +/- 220 gm), and mean gestation (27 +/- 2 weeks) of the PPC cohort was similar to the control cohort. Thirty-two (68%) of the infants with PPC were male, compared with 691 (53%) of the ventilated infants (p < 0.05). Eight (17%) of the infants with PPC survived, compared with 780 (60%) of the control cohort (p < 0.00001). The oxygenation index significantly increased before PPC, and was significantly higher in nonsurvivors than survivors. Four (50%) of the PPC survivors had neurodevelopmental impairment at 20 months, compared with 35% of the control cohort. Pneumopericardium is a rare event with high morbidity and mortality. Clinicians should suspect this diagnosis in VLBW infants with a rising oxygenation index and subsequent acute deterioration.
