Sleep Apnea and Fetal Growth Restriction

2019-09-15 03:11:39 | BioPortfolio

Summary

This study aims to evaluate the association between obstructive sleep apnea (OSA) and fetal growth restriction (FGR) and to assess the role of auto-titrated positive airway pressure (aPAP) as antenatal therapy in these patients. Pregnant patients with diagnosed FGR will be screened for OSA first by screening questionnaire and then by home sleep monitor. Of those patients diagnosed with OSA, half will be assigned to use aPAP each night when sleeping and half will not (standard care).

Description

Fetal growth restriction (FGR) affects 5-10% of pregnancies and is one of the leading causes of perinatal morbidity and mortality.

Obstructive sleep apnea (OSA) is a common disorder in which a person's breathing pauses or becomes shallow during sleep. These periods of low oxygen lead stress and inflammation which that may be harmful to both the mother and her fetus. OSA in pregnancy has been associated with poor maternal-fetal outcomes, including low birth weight, preterm delivery, FGR, gestational hypertension/preeclampsia, gestational diabetes and higher rates of neonatal ICU admission.

Auto-titrated positive airway pressure (aPAP) is a machine that gently delivers pressurized air via a mask to keep a patient's airways free of obstruction during sleep. It is currently unclear whether treatment of OSA during pregnancy in women with known FGR can improve fetal and neonatal outcomes.

Medical and Biotech [MESH] Definitions

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)

HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.
