Premature rupture of the membranes and barometric pressure changes.
Barometric pressure changes are thought to possibly affect premature rupture of the membranes. One hundred nine patients with this obstetric complication lived within an area small enough to be subject to the same barometric pressure changes; onset of labor was used as a comparison point in 109 control patients. The two groups did not differ when demographic data were compared. There were no differences in other obstetric complications or neonatal outcome. There was a significant increase, however, in premature membrane rupture within three hours after a fall in barometric pressure. No such increase in the onset of labor was seen in the control group.
