    Obesity is linked to reduced hemodynamic response and prolonged vasopressor dependency in septic shock patients receiving arginine vasopressin.

  • 2

    Normal weight patients showed a significant decrease in norepinephrine (NE) requirements after initiating vasopressin compared to overweight and obese patients.

  • 3

    Each 5 kg/m2 increase in BMI correlated with a 2.7% lesser reduction in NE requirement after vasopressin initiation.

  • 4

    BMI-adjusted dosing of vasopressin did not significantly alter NE requirements compared to fixed-dose administration across BMI categories.

  • 5

    The interaction between vasopressin dose, time, and BMI was significant, indicating varying responses to vasopressin based on BMI.
