Adventitious respiratory sounds in children with respiratory infection

Abstract

Enquadramento: As infeções respiratórias do tracto inferior (IRTI) são a principal causa de visitas/admissões hospitalares em crianças com idade inferior a 5 anos. Desta forma, verifica-se uma urgente necessidade de desenvolver medidas de avaliação respiratória pediátricas que sejam objetivas, fiáveis e de rápida aplicação. Os sons respiratórios adventícios (SRA) computorizados têmse revelado objetivos e fiáveis na avaliação/monitorização de doenças respiratórias; contudo a sua aplicação em pediatria é desconhecida. Objetivos: Caracterizar/comparar os SRA em crianças saudáveis e com IRTI. Métodos: Um estudo transversal descritivo-comparativo foi realizado em três instituições de saúde. As crianças foram diagnosticadas pelo pediatra como saudáveis ou com IRTI e agrupadas de acordo com a sua idade (i.e., 0-2 anos ou 3-5 anos). Dados antropométricos, sócio-demográficos, cardio-respiratório e tipo/severidade da IRTI foram recolhidos. Os sons respiratórios foram foram recolhidos no tórax com um estetoscópio digital, de acordo com as orientações internacionais. A localização, número médio, tipo, frequência e taxa de ocupação das sibilâncias e a localização número médio, tipo, frequência, initial deflection width, two cycle duration, e largest deflection width dos fervores foram analizados por fase respiratória. Resultados: Quarenta crianças participaram neste estudo: 22 com idades entre is 0-2 anos (G1: 11 saudáveis; G2: 11 com IRTI) e 18 com idades entre os 3-5 anos (G3: 9 saudáveis; G4: 9 com IRTI). Poucas crianças de ambos os grupos apresentaram sibilâncias. Para ambas as faixas etárias as crianças com IRTI apresentaram uma maior percentagem da expiração ocupada por sibilâncias (G1: M 2.15 IQR 1.45 vs. G2: M 4.73 IQR 6.72 p=0.001; G3: M 2.80 IQR 3.27 vs. G4: M 5.17 IQR 15.99 p=0.07). Todas as crianças apresentaram fervores em pelo menos um local de auscultação. Em ambas as faixas etárias, aqueles com IRTI apresentaram mais fervores inspiratórios (G1: M 0.25 IQR 0.31 vs. G2: M 0.52 IQR 0.70; p<0.001; G3: M 0.50 IQR 0.49 vs. G4: M 0.70 IQR 0.21 p=0.03), especialmente fervores crepitantes , (G1: M 0.07 IQR 0.13 vs. G2: M 0.18 IQR 0.42 p=0.001; G3: M 0.11 IQR 0.21 vs. G4: M 0.17 IQR 0.23 p=0.001). Os fervores expiratórios subcrepitantes foram os mais comuns entre todas as crianças (G1: M 0.33 IQR 0.56; G2: M 0.33 IQR 0.56; G3: M 0.56 IQR 0.99; G4: M 1.14 IQR 1.38).Não foram encontradas diferenças relativamente aos restantes parâmetros avaliados. Conclusão: Crianças saudáveis e com IRTI de diferentes faixas etárias apresentam SRA (i.e., sibilâncias e fervores). A taxa de ocupação das sibilâncias e o número de fervores foram as características que apresentaram mais diferenças entre os participantes saudáveis e os participantes com IRTI. Desta forma, conclui-se que estas características dos SRA poderão constituir os melhores critérios de discriminação entre os grupos.

Background: Lower respiratory tract infections (LRTI) are the leading cause of hospital visits in children under 5 years old. Therefore, there is an urgent and unmet need to develop objective, reliable and quick measures for respiratory paediatric assessment. Computerised adventitious respiratory sounds (ARS) have shown to be objective and reliable to assess/monitor respiratory diseases; however its application in children with LRTI is unknown. Aim: To characterise/compare ARS in healthy children and children with LRTI. Methods: A cross-sectional descriptive-comparative study was conducted in three healthcare institutions. Children were diagnosed by the paediatrician as healthy or with a LRTI and grouped according to their age (i.e, 0-2 years old or 3-5 years old). Socio-demographic and anthropometric data, type and severity of LRTI and cardio-respiratory parameters were collected. Respiratory sounds were recorded from the chest with a digital stethoscope following the Computerised Respiratory Sound Analysis guidelines. Wheezes’ location, mean number, type, frequency and occupation rate and crackles’ location, mean number, type, frequency, initial deflection width, two cycle duration, and largest deflection width were analysed per breathing phase. Results: Forty children enrolled in this study: 22 aged 0-2 years old (G1: 11 healthy; G2: 11 with LRTI) and 18 aged 3-5 years old (G3: 9 healthy; G4: 9 with LRTI). Few children, both healthy and with LRTI presented wheezes. In both age ranges, children with LRTI presented a higher percentage of the expiratory phase occupied by wheezes (G1: M 2.15 IQR 1.45 vs. G2: M 4.73 IQR 6.72 p=0.001; G3: M 2.80 IQR 3.27 vs. G4: M 5.17 IQR 15.99 p=0.07). Crackles were found in all children in at least one chest location. In both age ranges, children with LRTI presented more inspiratory crackles (G1: M 0.25 IQR 0.31 vs. G2: M 0.52 IQR 0.70; p<0.001; G3: M 0.50 IQR 0.49 vs. G4: M 0.70 IQR 0.21 p=0.03), especially fine crackles than healthy children (G1: M 0.07 IQR 0.13 vs. G2: M 0.18 IQR 0.42 p=0.001; G3: M 0.11 IQR 0.21 vs. G4: M 0.17 IQR 0.23 p=0.001). Coarse expiratory crackles were the most common type of crackle found in both healthy children (G1: M 0.33 IQR 0.56; G3: M 0.56 IQR 0.99) and children with LRTI (G2: M 0.33 IQR 0.56; G4: M 1.14 IQR 1.38). No differences were found for the remaining parameters. Conclusion: Healthy children and children with LRTI of different ages present ARS (i.e., crackles and wheezes). The occupation rate of wheezes and the mean number of crackles were the parameters that most differed between healthy children and children with LRTI in both age ranges. Therefore these ARS’ parameters may be the best criteria to discriminate the groups.
