[Premature rupture of the membranes and RDS incidence in prematures (author's transl)]
Insights
Prolonged rupture of membranes (ROM) over 12 hours before delivery may reduce respiratory distress syndrome (RDS) incidence in premature infants. This protective effect was statistically significant for newborns weighing 1500-2000g.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Medicine
- Perinatal Research
Context:
- Respiratory distress syndrome (RDS) is a significant concern in premature and dystrophic newborns.
- The timing of membrane rupture before delivery is a potential factor influencing neonatal outcomes.
- Understanding factors affecting RDS is crucial for improving infant survival and health.
Purpose:
- To investigate the relationship between the duration of membrane rupture before delivery and the incidence of RDS in premature infants.
- To assess the impact of membrane rupture timing on RDS in dystrophic newborns.
- To determine if labor duration influences RDS incidence in these infant groups.
Summary:
- A study analyzed 188 premature infants (1000-2500g) and 119 dystrophic newborns (1000-2500g) born between 1974-1976.
- A lower incidence of RDS was observed when membrane rupture exceeded 12 hours, particularly significant in premature infants weighing 1500-2000g.
- No statistically significant influence of labor duration on RDS incidence was found in either group.
Impact:
- Findings suggest that a longer interval between membrane rupture and delivery may be a protective factor against RDS in specific premature infant populations.
- This research contributes to understanding perinatal factors influencing neonatal respiratory health.
- Highlights the need for further investigation into the mechanisms underlying the protective effect of prolonged membrane rupture.
Abstract:
In the years 1974, 1975 and 1976 495 children were born alive with a birthweight less than 2500 g in the Ist Department of Gynecology and Obstetrics of the University of Vienna. We selected all cases with dystrophy or factors, which were a disposal for RDS, so we got a rest of 188 prematures with a weight from 1000 g to 2500 g. For these children we checked the influence of time of rupture of the membranes (ROM) before delivery to the incidence of RDS. We found a lower incidence of RDS of the newborns when duration of ROM exceeded the time of 12 hours. This fact was statistically significant in the class of premature newborns with a weight of 1500 g to 2000 g. The similar trend was found in 119 dystrophic newborns with a weight between 1000 g to 2500 g, although there was no statistical significance. No influence of duration of labor on the incidence of RDS neither in selected premature nor dystrophic newborns was found.
