Sleep Disordered Breathing in Women of Childbearing Age & During Pregnancy (Report)

Sleep apnoea is a prevalent, yet often unrecognized condition that may have major adverse consequences for women in their childbearing years. By far the most common form of sleep apnoea is obstructive sleep apnoea (OSA), where repeated dynamic collapse of the upper airway during sleep leads to frequent, intermittent cessation of airflow despite ongoing respiratory efforts. Upper airway resistance syndrome, a milder form of obstructive sleep apnoea syndrome (OSAS) is characterized by increasing respiratory efforts to maintain breathing and is terminated by an arousal. It is part of the continuum of OSA (1) though it may require special diagnostic technology to demonstrate its presence (2). Rarely disorders of ventilatory drive can lead to central sleep apnoea, characterized by repeated pauses in respiratory efforts. Oxygen desaturation may occur with both types of sleep apnoea. These respiratory disturbances are often terminated by transient arousals from sleep, which are associated with re-opening of the airways or resumption of respiratory efforts. OSAS was first recognized among older obese men who presented with excessive daytime sleepiness, loud habitual snoring and witnessed apnoeas. Though this classic presentation holds true, it does not represent the only presentation of OSAS in the general population. Overemphasis on this presentation may hinder the recognition of different presentations including among the younger, non obese individuals and women. Since the first retrieved case report of OSA in pregnancy in 1978 (3), there are several studies supporting an association between OSA and hypertensive disorders of pregnancy, suggesting that OSA does not spare younger women.
