Abstract
PURPOSE: The aim of this study was to investigate the therapeutic results and effects of propranolol on cardiovascular parameters in infants receiving systemic propranolol for complicated infantile hemangiomas (IHs), as well as to evaluate the adverse effects of propranolol throughout the course of treatment. MATERIALS AND METHODS: Twenty-five consecutive patients who presented with complicated IHs were prospectively recruited into this study between April 2012 and June 2013. All patients were treated with systemic propranolol at a dose of 1.0 to 1.5 mg/kg, and the drug was taken once per day. The length of treatment was 8.2 months on average and ranged from 6 to 12 months. The follow-up visits were scheduled monthly after discharge. Changes were recorded during the 3-day hospitalization, including systolic and diastolic blood pressures, heart rate, and blood glucose level. The treatment responses were scored according to a 4-point scale system as very good, good, mild, or no response. The adverse effects after medication administration were evaluated and managed accordingly. RESULTS: Of the 25 patients, 8 (32%) had a very good response, 11 (44%) had a good response, and 6 (24%) had a mild response. When pretreatment and post-treatment values were compared, there was no significant decrease in mean systolic and diastolic blood pressures and mean heart rate (all P > .05). The decreases in the cardiovascular parameters were not commonly associated with observable clinical symptoms. No major collateral effects were observed, and no infants were withdrawn from treatment because of side effects. CONCLUSIONS: Fluctuations from the normal ranges of cardiovascular parameters occurred frequently with the initiation of propranolol, but were clinically asymptomatic. Therefore oral propranolol was an effective and safe treatment for IHs, particularly for early intervention suitable for severe IHs.
