OSAS IN PREGNANCY

Scope: figure out the pregnant women that are affected by Obstructive Sleep Apnea Syndrome ( OSAS), in oreder to recognise precociously possible cases of pypertension during pregnancy and to control precociously possible maternal-fetal implications. Strengthen the correlation between OSAS and gestational Hypertension and other diseases of metabolism to include the ORL evaluation among the preconception surveys to minimise the comorbidity of a programmed pregnancy Materials and methods: We studied during a period of 18 months, 487 pregnant women form the province of Verona. Women with pre-existing hypertension, obesity, patients with previous OSAS diagnosis and over 40 years were excluded from the study. We administered all patients with a questionnaire designed by us on the basis of questionnaires validated by Epworth and Berlin that were modified on the basis of physiological changes ( the weight of the child at birth, term pregnancy, dysmetabolism during pregnancy) and tha areas of origin of the family. Starting from the II trimester of the pregnancy women were subjected to a polysomnography. Results: Involving 97 pregnant women who presented hypertension after the 20th week ( gestational hypertension) 88%were affected by OSAS between moderate and severe ( AHI>= 30). On Statistical analysis the difference between the AHI and the pressure values were higly significant ( p<0.001) Conclusion: Polysomnography is a cheap test, without any side effects that allows to identify a category of pregnant women that are at risk of developing gestational hypertension.
