Congenital paraplegia following maternal hypotension.

Congenital paraplegia, with partial improvement over the first months of life, occurred in a female neonate born at 35 weeks' gestation, whose mother had suffered hypotension and hypoxaemia due to anaphylaxis 12 weeks earlier. Our patient subsequently had an acute encephalopathy during a respiratory illness with later developmental delay. We speculate that the baby's paraplegia resulted from spinal-cord ischaemia in utero.

Hypoxaemia in infants with respiratory tract infections.

Nineteen infants who were graduates from special care baby units underwent two overnight tape recordings of oxygen saturation (SaO2) and breathing movements; one during an upper (n = 12) or lower (n = 7) respiratory tract infection and the other when free of infection. Baseline SaO2 was lower during infection (median 99.6 vs 100%, p less than 0.

Arterial oxygen saturation in preterm infants at discharge from the hospital and six weeks later.

To obtain normal data on arterial oxygen saturation (SaO2) in preterm infants and to study early developmental changes in SaO2, we obtained overnight tape recordings of SaO2 and breathing movements in 160 preterm infants at their discharge from three special care baby units (mean gestational age at birth 33 weeks; at time of study, 37 weeks). One hundred ten infants (69%) underwent a second recording 6 weeks later. Median baseline SaO2 during regular breathing was 99.

Oxygen saturation and breathing patterns in infancy. 2: Preterm infants at discharge from special care.

Overnight 12 hour tape recordings of arterial oxygen saturation (SaO2, pulse oximeter in the beat to beat mode), breathing movements, and airflow were made on 66 preterm infants (median gestational age 34 weeks, range 25-36) who had reached term (37 weeks) and were ready for discharge from the special care baby unit. No infant was given additional inspired oxygen during the study. The median baseline SaO2 was 99.
