Multicenter Study
The outcome of 72 pregnancies in 55 women with cystic fibrosis in the United Kingdom 1977-1996.
To identify pregnancies in women with cystic fibrosis and describe obstetric, infant and maternal medical outcomes in relation to the severity of maternal disease. ⋯ Pregnancy occurs in women with cystic fibrosis of all degrees of severity. Outcomes for the infant are generally good but are variable for the mother. Predicting outcome on the basis of maternal severity is difficult but lung function appears to be the most significant determining factor. Pregnancy may be normal in women with normal lung function (forced expiratory volume > 80%). However, it may adversely affect mild and moderate lung disease due to cystic fibrosis and should be avoided in pulmonary hypertension, cor pulmonale and when forced expiratory volume < 50% predicted. Ideally, all pregnancies should be planned with prior counselling and monitored by dedicated cystic fibrosis teams, including obstetricians who are experienced in managing high risk pregnancies.
