AbstractSevere 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 intubated and ventilated with 100% oxygen, intravenous epinephrine (1 mg over 2 min) had no effect on blood pressure. After injection of 10 IU vasopressin, followed by infusion of 40 IU vasopressin, hemodynamics could be stabilized at once. In the second case, a 47-year-old male patient was stung by a wasp. At the scene he was unconscious, blood pressure was not measurable, heart rate was 140/min. 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.Copyright 2004 S.
