Case ReportsSuccessful treatment of severe anaphylactic shock with vasopressin. Two case reports.
Severe anaphylactic shock is a life-threatening situation that needs immediate treatment of progressive hemodynamic failure. We report two cases of severe anaphylactic shock treated with arginine-vasopressin (AVP): In a 42-year-old male patient anaphylactic shock was caused by the sting of a hornet. At the scene, he was found unconscious, cyanotic, with a heart rate of 130/min without measurable blood pressure. ⋯ The patient was treated with 40 IU vasopressin followed by rapid infusion of 500 ml NaCl 0.9%. After injection of vasopressin, blood pressure raised to 80/50 mm Hg and heart rate decreased to 90/min. Both patients needed ventilator therapy for several days and recovered fully.
