Management of Septic Shock in Elderly Patients

Initial Assessment and Resuscitation

The American College of Critical Care Medicine recommends administering at least 30 mL/kg of crystalloids in the first 3 hours of resuscitation to patients with septic shock, with the goal of achieving a mean arterial pressure (MAP) of 65 mmHg 3, 2
The Society of Critical Care Medicine suggests verifying central venous access for safe administration of vasopressors in patients with septic shock 1, 2
Continuous monitoring with an arterial catheter is recommended if not already in place, to closely monitor blood pressure and adjust vasopressor therapy as needed 1, 2
The goal is to maintain a MAP of 65 mmHg or higher, as recommended by the Surviving Sepsis Campaign 3, 1, 2

The Society of Critical Care Medicine recommends adding vasopressin at a fixed dose of 0.03 units/minute to patients with septic shock who require high doses of norepinephrine, rather than increasing the norepinephrine dose further 1, 2
Vasopressin acts on different vascular receptors (V1) than alpha-1 adrenergic receptors, providing a complementary mechanism of vasoconstriction 1, 2
The maximum dose of vasopressin should not exceed 0.03-0.04 units/minute, except as a rescue therapy, due to the risk of cardiac, digital, and splanchic ischemia 3, 1, 2

If the patient remains hypotensive despite the addition of vasopressin, epinefrine should be added as a third vasopressor agent at a dose of 0.05-2 mcg/kg/minute, rather than increasing the norepinephrine or vasopressin dose further 4, 1, 2
Dobutamine may be considered at a dose of up to 20 mcg/kg/minute if there is evidence of myocardial dysfunction with persistent hypoperfusion despite adequate vasopressor support 3, 1, 2

Hydrocortisone 200 mg/day (50 mg IV every 6 hours) may be considered if the patient remains refractory to hypotension after 4 hours of norepinephrine or epinephrine at a dose of 0.25 mcg/kg/minute or higher, or if the patient fails to achieve hemodynamic stability despite adequate fluid resuscitation and vasopressor support 4, 5

The Society of Critical Care Medicine recommends continuous monitoring of tissue perfusion markers, including lactate levels, urine output, mental status, and capillary refill, in addition to blood pressure 1, 2, 4, 3

Dopamine should not be used as a first-line vasopressor due to its association with increased mortality and arrhythmias compared to norepinephrine 1, 2
Low-dose dopamine for "renal protection" is strongly contraindicated and offers no benefit 1, 2
Phenylephrine should not be used except in cases where norepinephrine causes severe arrhythmias or as a rescue therapy when other agents have failed 1, 2
