Hereditary angioedema:  a survey of UK emergency departments and recommendations for management.
Patients with hereditary angioedema may present to the emergency department (ED) with subcutaneous and submucosal swellings, the most important being the development of laryngeal oedema, which can rapidly obstruct the airways and cause death. The aim of this study was to establish whether local guidelines exist for the management of such patients and to determine where the C1 inhibitor concentrate (C1 INHC) was kept in the trusts. A questionnaire survey of the availability and use of C1 INHC was sent to 35 EDs across the UK with established immunology services within their trusts. A hundred percent response was received. Thirty-three trusts had a supply of the drug C1 INHC in varying quantities. Nineteen trusts had it in their ED. Only 17 departments had any guidance with regard to their use. There is a significant lack of guidance for C1 INHC use in the EDs surveyed. A guideline was developed as a result that can be used by EDs across Europe.
