Predictors of severe chest infections in pediatric neuromuscular disorders.
Chest infections are serious complications in neuromuscular disorders. The predictive values of lung and respiratory muscle function including peak cough flow still remain unclear. We performed retrospective analysis of 46 children and adolescents (12.7+/-3.7 years) in whom lung function, respiratory muscle function and peak cough flows had been obtained. ⋯ IVC<1.1l and PCF<160 l/min were specific and sensitive thresholds to discriminate between patients who had already suffered severe chest infections and those who had not. Therefore, spirometry and peak cough flow are reliable tests to identify patients at high risk for severe chest infections. Patients with IVC below 1.1l and/or PCF below 160 l/min should be well monitored and introduced to assisted coughing techniques.
