Association of Adenotonsillectomy With Blood Pressure Among Hypertensive and Nonhypertensive Children With Obstructive Sleep Apnea

Abstract
Obstructive sleep apnea (OSA) comprises a spectrum of repetitive episodes of partial to complete obstruction of the upper airway during sleep.1,2 In adults, OSA correlates with hypertension and sequential cardiovascular morbidities.3,4 High blood pressure (BP) in children with OSA was first described by Guilleminault et al5 in 1976. Although in 2007 Zintzaras and Kaditis6 reported in a meta-analysis that the associated evidence between moderate to severe childhood OSA and hypertension is insufficient, several subsequent studies7-12 have suggested otherwise. Kang et al13 reported that children with moderate to severe OSA have higher ambulatory BP compared with those who are primary snorers. Li et al14 reported that OSA is associated with elevated daytime and nocturnal BP.
