Abstract:
Objective To explore the clinical modalities and diagnosis of respiratory failure due to laryngotracheal disorders in children,in order to reduce the misdiagnosis.Methods Fifteen patients(11 cases were male,4 cases were female) with respiratory failure in Intensive Care Unit, Tianjin Children′s Hospital from Jul.2006 to Jul.2009 were selected.Data including history,characteristics and results of spiral computerized tomography(CT) and reconstruction and magnetic resonance imaging(MRI) were reviewed.Results The major clinical manifestations indicated that 7 cases had laryngeal stridor,6 cases had recurrent pneumonia,5 cases had cyanosis after crying,and 12 patients were complicated with respiratory failure in 12 hours.Nine cases were recovered,3 cases were given up,and 3 cases died.All patients were performed with CT about laryngohypopharynx,and the results were cyst of root of tongue in 3 cases,trachea pressed by cyst of parapharyngeal space in 1 case.There were 11 cases examined by spiral CT and reconstruction,in which 6 cases were confirmed as tracheal stenosis,2 cases were left bifid tracheostoma,2 cases were pulmonary artery sling,and 1 case was diagnosed as tracheomalacia.Chest X-ray radiograph indicated that bronchopneumonia in 8 cases,bronchitis in 3 cases and negative in 4 cases.Echocardiograph examination was performed among 11 cases,in which 2 cases were pulmonary artery sling,2 cases were atrial septal defect,1 case was patent ductus arteriosus, and 6 cases were negative.Conclusions There is high morbidity of respiratory failure caused by laryngotracheal disorders in infants,but misdiagnosis ccures usually because of non-specific symptoms.If the infant must depend on mechanic ventilation for a long time and has airway obstruction,he should be examined early by using spiral CT.
