| Spanish abstract | Objetivo. Evaluar el signo del "cabeceo" como indicador de hipoxemia en ninos con neumonia. Material y metodos. Se estudiaron 62 menores de 5 anos de edad. Se definio hipoxemia a la saturacion de oxigeno <94% registrada mediante oximetria de pulso. La validez del signo se evaluo mediante tres puntos de corte (<94%, . 90%, . 84%). Resultados. La prevalencia de hipoxemia fue de 56.5%. El cabeceo se encontro en 40 (64.5%) pacientes, de ellos, 30 tenian neumonia y 73.1% presentaba hipoxemia. El cabeceo mostro una sensibilidad de 73.2% y una especificidad de 52.4%. La precision del signo fue mayor al usar el nivel de corte <94%. El cabeceo fue un mejor indice de hipoxemia en ninos menores de 1 ano. Conclusiones. El cabeceo es un buen predictor de hipoxemia en ninos con neumonia. Es un signo facilmente reconocible que puede ser ensenado a padres y trabajadores de la salud |
| English abstract | Objective. To assess the clinical usefulness of the head nodding sign (HN) in children with pneumonia. Material and Methods. Cross-sectional study that included 62 children aged 2-59 months. Hypoxemia was defined as arterial oxygen saturation <94% measured by pulse oximetry. HN was examined with regard to three levels of hypoxemia (<94%, . 90%, . 84%). Results. The overall prevalence of hypoxemia was 56.5 %. HN was observed in 64.5% (40) of the patients, 48.4% (30) of those had pneumonia and 73.1% were hypoxemic. HN showed a sensitivity of 73.2% and a specificity of 52.4%. Accuracy of HN was better when a cut off level <94% was used. HN in infants was a better index for hypoxemia than for older children. Conclusions. HN was a good predictor of hypoxemia in children with pneumonia. It seems that HN is an easily recognizable sign, and it could be easily taught to parents and health workers |
