Abstract
Purpose
Our study aimed to determine the effect of continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA) on the incidence and severity of hypertensive syndrome in pregnancy.
Methods
The study included women with high-risk pregnancies and the Epworth Sleepiness Scale score ≥ of 10. Polygraphic testing was done between 18 and 20 weeks. Participants were divided into three groups: pregnant women with OSA starting treatment with CPAP for 4 weeks between 24 and 28 gestational weeks, women with OSA treated conservatively, and women without OSA as the control group. Participants were followed up regularly for 4 weeks until the delivery and 1 week after for the occurrence of hypertensive syndrome and other maternal complications.
Results
Among the 110 women enrolled in the study, the prevalence of hypertensive syndrome in 41 pregnant women with OSA treated conservatively was 39%, 50 women with OSA treated with CPAP 26%, and 19 women in the control group 21%, p = 0.1. The group treated with CPAP when compared with the conservatively treated group had a significantly lower incidence of severe forms of hypertensive syndrome (8% vs. 24%, p = 0.02.), and after 1 month of treatment had higher night oxygen saturation (92%, vs. 87%, p = 0.003) and lower Epworth Sleepiness Scale score (respectively, 4.2 ± 2.3 vs. 9.4 ± 4.1, p < 0001). The respiratory event index was significantly associated with hypertension severity (patients with preeclampsia 9.5 ± 4.9 vs. without hypertension 6.9 ± 4.5, p = 0.04).
Conclusion
CPAP therapy significantly reduced the incidence of severe forms of hypertensive syndrome in pregnant women with OSA.
