Maternal and Fetal Outcomes for Parturients with Obstructive Sleep Apnea: A Retrospective Cohort
Abstract Number: F2B-1
Abstract Type: Original Research
Background: Due to dynamic physiologic and hormonal changes in pregnancy, pregnant women are predisposed to obstructive sleep apnea (OSA). CPAP has been proven to be a safe and effective treatment for OSA. The purpose of this study is to examine the influence of CPAP treatment on maternal and fetal comorbidities and outcomes of pregnant women with OSA.
We retrospectively reviewed a cohort of parturients who were diagnosed OSA during pregnancy. Demographic data, maternal information related to delivery and anesthesia, and newborn characteristics were collected.
102 patients’ charts were reviewed, among which 33 (32.4%) had treatment for OSA. We did not detect any significant differences in maternal characteristics and offspring outcomes between the treated and untreated groups. Fetal gestational age at delivery was significantly different between the groups (267 days in Untreated vs 273 days in Treated Group) (p=0.021). (Table 1).
In our study, the incidence of cesarean delivery among OSA parturients was 81.6% which was above the average ratio of 28%. Depression/anxiety, migraine and asthma are common in OSA parturients, with the occurrences at 48%, 42% and 28%, respectively. To anesthesiologists, parturients with OSA have higher requirements for both airway and neuraxial management, as they can be very challenging. The use of multimodal analgesia may be more beneficial to minimize the opioid-related side effects while also providing effective analgesia.
A multidisciplinary approach involving the obstetrician, anesthesiologists, neonatologist and sleep physician will minimize OSA related complications during the peripartum period.
