title: Idiopathic non-histaminergic angio-oedema after routine extubation successfully treated with fresh frozen plasma.
abstract: Non-allergic angio-oedema is a potentially life-threatening condition typically seen in patients with hereditary or acquired angio-oedema caused by C1 inhibitor deficiency or an adverse drug reaction to angiotensin converting enzyme inhibitors. We report a case of sudden angio-oedema in a patient who developed severe swelling of the tongue and neck after routine extubation requiring resuscitative re-intubation. The oedema was refractory to conventional allergy treatment. Shortly thereafter, the patient was treated with fresh frozen plasma, and within a few hours his condition improved, allowing extubation. Familial history and exposure to potentially angio-oedema causative drugs were not evident. The serum complement status was normal, and no IgE sensitisation was detected. We therefore concluded that the patient was suffering from idiopathic non-histaminergic angio-oedema. To our knowledge, this is the first reported case of an acute, life-threatening attack of idiopathic non-histaminergic angio-oedema that was successfully treated with fresh frozen plasma.
