Resumo
Introdução: A Síndrome de Apnéia Hipopnéia Obstrutiva do Sono é um distúrbio caracterizado por episódios repetidos de obstrução parcial ou completa da via aérea superior durante o sono, resultando em hipóxia intermitente, hipercapnia e fragmentação do sono. Afeta 0,7% a 3% das crianças na faixa etária pré-escolar, e está, nas crianças, relacionada com a hipertrofia das tonsilas palatina e/ou faríngeas. Em adultos, a SAHOS foi relacionada como fator de risco para doenças cardiovasculares e distúrbios metabólicos. Em crianças, há poucos relatos de alterações cardíacas como cor pulmonale ou HAS. Porém, as evidências fisiopatológicas da SAHOS permitem suspeitar que haja alterações estruturais e funcionais cardíacas, notadamente do ventrículo direito. Objetivos: Avaliar a função cardíaca de crianças com distúrbios respiratórios obstrutivos por hipertrofia das tonsilas, antes e após a cirurgia de adeno- e/ou tonsilectomia. Casuística e Métodos: Foram estudadas 40 crianças, de ambos os sexos, com idade entre 3 a 11 anos, das quais 30 estavam em seguimento no Ambulatório de Distúrbios do Sono, da disciplina de Otorrinolaringologia, FMB – UNESP, aguardando cirurgia de adeno- e/ou tonsilectomia por hipertrofia das tonsilas e distúrbios respiratórios obstrutivos, caracterizados por roncos, pausas respiratórias referidas e sono agitado. As outras 10 crianças eram controles saudáveis, os dois grupos estando homogêneos em relação ao sexo, idade, peso e altura. Todas as 40 crianças foram submetidas...
Introduction: Obstructive sleep apnea is characterized by intermittent partial or complete obstruction of the upper airway, causing hypoxemia, hypercapnia and sleep fragmentation. It affects 0,7% to 3% of the pre-school children, and in children it is closely related to enlarged tonsils. In adults, sleep apnea has been described as na independent risk factor for cardiovascular disease and metabolic disorders. In children, there a few studies for cardiovascular disfunction, most of them related to cor pulmonale or hypertension. Even though, the pathophysiologic mechanism of OSA permit to suspect of structural and functional cardiac changes, mostly of the right chambers. Aim: To study the heart function in children with sleep-related breathing disorders and enlarged tonsils, before and after adeno- and/or tonsillectomy. Patients and Methods: We studied 40 children, of both genders, aged between 3 and 11 years. Thirty children were at follow-up of Botucatu Medical School – State University of São Paulo due to hypertrophy of the tonsils and clincal complaints of Obstructive Sleep Apnea, as snoring, referred apneas and restless sleep. The other ten children were healthy controls; both groups were homogeneous in gender, age, weight and height. All 40 children were submitted to echocardiogram, analysing the four chambers, in systole and diastole. We obtained measures for diameter, area, variation of area, ejection fraction and the flow of tricuspid, pulmonary, mitral and aortic valves. Special attention was given to the right chambers, obtaining diameter, area and variation of area, measures not routinely in an echocardiogram. The 30 children of the patient’s group realised the echocardiogram up to one month before and four months after surgery... (Complete abstract, click electronic access below)
