Our facility has been seeing an increasing number of patients presenting in the ER with angioedema. We've ha at least 4 in the last 6wks. The tongue swelling is impressive to say the least. We've managed to secure their airways with a variety of techniques and have not had to emergently trach anyone yet. I'm just wondering if you all have noticed an increase in this where you live. My hypothesis is that ACE inhibitors are being prescribed more often and this side effect is then being seen.
