Abstract

Introduction: Estrogen induced hyperemia and nasopharyngeal mucosal edema leading to upper airway congestion with hypervolemia of pregnancy increases the risk of Sleep disordered breathing (SDB). Milder degree of SDB can also have adverse impact in pregnant women. The exact prevalence of OSA in pregnancy is not known.Cardiac output increases during pregnancy. Very few studies have been conducted to investigate the response of postural changes on cardiac output. Screening the pregnant women for SDB and monitoring of heart rate and blood pressure can prevent any associated mortality and morbidity. Hence this study was designed to assess the prevalence of breathing disorders and the effect of lying position on heart rate and blood pressure among pregnant women. Materials and Method: This was a cross sectional study conducted in 90 normal pregnant women selected by purposive sampling. They were included into three groups based on their trimester. Standardised and validated BERLIN questionnaire was given to the subjects based on which diagnosis of SDB was made and counted. The subjects were asked to lie in different positions (supine, left lateral, right lateral and semi fowlers) and relax for five minutes. After which heart rate and blood pressure were measured. ANOVA and Pearson’s correlation was used for statistical analysis. Results: Breathing disorders were highest during third trimester of pregnancy (43.3%) when compared to second and third (26.7%). There was a significant difference in mean Left lateral SBP (1st Trimester: 92.20±10.96; 2nd Trimester: 104.40±17.84; 3rd Trimester: 108.83±11.98) and DBP (1st Trimester: 53.90±10.65; 2nd Trimester: 54.77±15.56; 3rd Trimester: 64.87±11.7) between trimesters. Mean Left lateral SBP (p<0.001) and DBP (p=0.002) were significantly higher in third trimester. There was no significant difference in mean Supine, Right lateral and Semi fowlers SBP and DBP between trimesters. Mean Left lateral SBP and DBP were lower than other SBP and DBP. Conclusion: The prevalence of SDB increased in third trimester. Left lateral SBP and DBP were lower than others.
