THE EFFECT OF RESPIRATORY-DISTRESS SYNDROME ON CHEST WALL MOVEMENTS AND RESPIRATORY PAUSES IN PRETERM INFANTS
The American review of respiratory disease(1982)
摘要
We studied the influence of respiratory distress syndrome (RDS) on the patterns of chest wall movements and respiratory pauses in preterm infants during the first week of life. Eight infants with mild-to-moderate RDS and 10 healthy preterm infants (non-RDS group) were evaluated on Days 1, 3, and 7. Chest wall movements were measured by strain gauges over the upper (URC) and lower (LRC) rib cage and abdomen. Respiratory pauses were determined from both a nasal thermistor and chest wall movements. In the RDS infants the incidence of asynchronous URC and abdominal movements increased from 3 ± 1% and 8 ± 3% (mean ± SEM) on Days 1 and 3, respectively, to 38 ± 5% by day 7 (p < 0.01). Furthermore, on Days 1 and 3 asynchronous URC movements occurred more frequently in the non-RDS infants (15 ± 5% and 30 ± 7%, respectively; p < 0.05) when compared with the RDS infants, but by Day 7 both groups were comparable. In the RDS infants, respiratory pauses ⩾ 5 s and ⩾ 10 s were rare on Days 1 and 3 and increased significa...
