Laryngeal edema: adrenocorticotropic hormones such as prednisolone, hydrocortisone, dexamethasone, etc., can reduce swelling and anti-inflammatory, mainly for laryngeal edema caused by bronchospasm patients. For laryngeal edema caused by dyspnea, if the above treatment is ineffective, tracheotomy is feasible. 3.
