Background: In this article, we present a clinical case of refractory septic shock resulting from intestinal perforation treated with high doses of vasopressin and hydrocortisone during emergency surgery. The use of such high doses of vasopressin for this type of shock is not described in the literature.
Case presentation: A 49-year-old white woman with grade III obesity, Crohn's disease, and an intestinal perforation presented with refractory septic shock. Initially, a low dose of vasopressin was used. Then, the dosage was increased to 0.4 U/minute; in the literature, this is defined as "salvage therapy." This therapy consists of an initial load followed by a continuous infusion of hydrocortisone.
Conclusions: The significant increase in her cardiac index and stroke volume index resulted in an improvement in peripheral resistance, gas exchange, and urine output and a decrease in her heart rate, interleukin-6 level, and tumor necrosis factor-α level. The administration of high doses of vasopressin and corticosteroids was demonstrated to be safe for the immune system, to reduce the systemic inflammatory response, and to have direct cardiovascular effects. Further studies are required to examine the use of vasopressin as an initial vasopressor as well as its use in high dosages and in combination with corticosteroids.
