Children with obstructive sleep apnea (OSA) and hypertension experienced significant improvements in blood pressure after adenotonsillectomy, according the results of a retrospective case series study published in JAMA Otolaryngology—Head & Neck Surgery, reports Pulmonology Advisor. All children with OSA underwent adenotonsillectomy. Blood pressure (BP) was measured in a sleep center before (nocturnal BP) and after (morning BP) polysomnography. All patients experienced a significant decrease in nocturnal diastolic BP (from 66.9 to 64.5 mm Hg; 95% CI of difference, ?4.1 to ?0.7 mm Hg) and morning diastolic BP (from 66.9 to 64.4 mm Hg; 95% CI of difference, ?4.2 to ?0.8 mm Hg). The percentage of patients with diastolic BP in the >95th percentile decreased significantly from 20.0% to 13.8% (nocturnal BP; 95% CI of difference, ?12.1% to ?0.4%) and from 21.7% to 14.2% (morning BP; 95% CI of difference, ?13.6% to ?1.4%).
