“Understanding Shock: The Receptor Level Logic Behind Vasopressor Choices”

Hi.. This is Dr. Sarath Nandanavanam MBBS MD Pharmacologist, India. Vasopressors and inotropes are routinely used in casualty and ICU settings — but the pharmacological reasoning behind their selection is often reduced to simplified algorithms. In this discussion, we explore the receptor-level logic and physiological nuances behind the use of: • Norepinephrine • Dobutamine • Dopamine • Vasopressin We compare their roles in cardiogenic shock and septic shock, focusing on: • Alpha-1, Beta-1 and V1 receptor physiology • Why norepinephrine is first-line in septic shock • When dobutamine truly adds value • The diminishing role of dopamine • The rationale for vasopressin as an adjunct • Hemodynamic subtleties often missed in routine practice This is not a comprehensive lecture. It is a reflective discussion on the clinical reasoning that often guides critical care decisions. Intended for doctors and healthcare professionals
