Abstract
To observe the efficacy of oral Propranolol in the treatment of infantile subglottic hemangioma. Eleven children (6 females and 5 males) with a median age at onset of treatment being 4 months were included in this study. Propranolol was given after laryngoscopy and a CT scan with contrast of the trachea confirming the presence of a subglottic hemangioma. The starting dose of Propranolol was 0.5 mg/kg per day, given in 2 or 3 divided doses. Heart rate and blood glucose were monitored during the treatment. If no side effects occurred, the dose was increased to 1 mg/kg per day at the third day and to 2 mg/kg per day at the sixth day. Treatment was continued at home after 10 days of inpatient treatment and the children were reevaluated monthly. After 24 - 48 hours of treatment, all of the children had improvement in their airway obstruction which was confirmed by fibro-laryngoscopy. The diameter of the subglottic stenosis from the hemangioma decreased from 3.9 - 5.0 mm to 1.5 - 2.0 mm,and the color was also lighter than before. In 3 children with cutaneous hemangioma, there was also significant improvement in the cutaneous lesions after treatment, with the color becoming lighter. There were no significant ECG, blood pressure or blood biochemical changes during the treatment. Two of the children had hypoglycemia at the first dose, but improved after blood transfusion and changing their diet. In five children, the treatment was stopped after 6 to 11 months when the obstructive symptoms improved. None of the children in this group had any evidence of recurrence. In the 5 children who stopped treatment, the obstructing mass in the subglottis was less than 10% of the diameter. Oral propranolol is a safe and effective treatment for infantile subglottic hemangioma. It may be used as a first-line therapeutic modality.
