Development of attention in preterm infants.

The quality of the awake state and attention in preterm infants has been evaluated by rating indices of attention such as widening of the eye, type of fixation, brightening, scanning, and cessation of sucking measured during visual fixation of patterns. Twenty-six infants ranging from 28 to 32 weeks' gestation at birth (mean, 31 weeks) were tested from one to four weeks postnatally until 36 weeks' gestation. Indices of attention were rated on a scale of 4 with an optimal mean index of 4. A progressive increase in behaviors associated with fixation of visual stimuli has been shown from 32 to 36 weeks of conceptual age. Mean scores ranged from 0.7 at 31 weeks' gestation to 1.8 at 34 weeks' and 2.7 at 36 weeks' gestation. The possibility therefore exists that by as early as 31 to 32 weeks from conception the human brain may be capable of waking states and thus able to process some sensory stimulation.rease in behaviors associated with fixation of visual stimuli has been shown from 32 to 36 weeks of conceptual age.

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.
