Propranolol use for infantile hemangiomas: American Society of Pediatric Otolaryngology Vascular Anomalies Task Force practice patterns.

IMPORTANCE This study provides multi-institutional practice guidelines for the initiation of propranolol hydrochloride treatment of routine infantile hemangiomas. OBJECTIVE To provide information on current propranolol treatment practices for infantile hemangiomas among a cohort of pediatric otolaryngologists. DESIGN AND SETTING A survey for initiation of propranolol therapy was created by the American Society of Pediatric Otolaryngology Vascular Anomalies Task Force Subcommittee. After an initial pilot of the survey by 4 task force members, the survey was modified and then distributed by e-mail. Results were transferred to spreadsheet format and analyzed. PARTICIPANTS All 51 members of the task force. RESULTS A total of 18 respondents from 15 institutions submitted completed surveys. Data from respondents at the same institution were aggregated and/or averaged to minimize regional bias. Fourteen of 15 responding institutions (93%) treat patients with infantile hemangioma as part of a multidisciplinary vascular anomalies team. Ten institutions (67%) routinely consult cardiology before initiation of propranolol therapy. The median propranolol hydrochloride initiation dosage is 2.00 (mean [SD], 1.65 [0.64]; range, 0.45-2.50) mg/kg/d. Postinitiation monitoring for propranolol therapy includes blood pressure (15 of 15 respondents [100%]), serum glucose levels (7 of 15 [47%]), and pulse oximetry (2 of 15 [13%]). Only 2 institutions routinely admit all patients for initiation of propranolol therapy. Typical duration of therapy ranges from 4 to 8 (5 of 15 [33%]) or 8 to 12 months (10 of 15 [67%]), and cessation of therapy in most cases is based on the clinical response (7 of 14 [50%]) or the age of the patient (6 of 14 [43%]). CONCLUSIONS AND RELEVANCE Propranolol is a commonly used medication for the treatment of infantile hemangiomas among otolaryngologists in the Vascular Anomalies Task Force. Propranolol therapy is commonly initiated in the outpatient setting and continued for as long as 12 months.
