From the Guidelines
The immediate management of global hypoperfusion in elderly women should begin with initial fluid resuscitation of 30 mL/kg of crystalloid within the first 3 hours, as recommended by the Surviving Sepsis Campaign guidelines 1.
Key Considerations
- Initial assessment and ongoing reevaluation of the response to treatment are crucial in managing these complex patients, including a thorough clinical examination and evaluation of available physiologic variables such as heart rate, blood pressure, arterial oxygen saturation, respiratory rate, temperature, and urine output.
- The use of central venous pressure (CVP) alone to guide fluid resuscitation is no longer justified 1, and dynamic measures such as passive leg raises, fluid challenges against stroke volume measurements, or the variations in systolic pressure, pulse pressure, or stroke volume to changes in intrathoracic pressure induced by mechanical ventilation should be considered.
- Mean arterial pressure (MAP) is the driving pressure of tissue perfusion, and below a certain threshold, tissue perfusion becomes linearly dependent on arterial pressure 1.
Management Approach
- Initial fluid resuscitation with 30 mL/kg of crystalloid within the first 3 hours, with further fluid administration guided by functional hemodynamic measurements.
- Continuous monitoring of vital signs and urine output to assess the response to treatment.
- Consideration of vasopressors, such as norepinephrine, if hypoperfusion persists despite fluid resuscitation, with careful titration to avoid excessive vasoconstriction.
- Identification and treatment of the underlying cause of hypoperfusion, whether sepsis, cardiac dysfunction, or hemorrhage, with appropriate interventions such as antibiotics, inotropes, or blood products.
Special Considerations in Elderly Women
- Elderly women are particularly vulnerable to fluid overload and medication side effects, requiring careful titration of interventions based on frequent reassessment.
- Early involvement of critical care specialists is recommended, as these patients often require intensive monitoring and may develop multiple organ dysfunction if hypoperfusion is prolonged.

From the Research
Immediate Management of Global Hypoperfusion in Elderly Women
The immediate management of global hypoperfusion in elderly women involves fluid resuscitation and the use of vasoactive agents.
- Fluid resuscitation is the mainstay of treatment, with the goal of restoring adequate blood pressure and perfusion of vital organs 3, 4, 5, 6.
- The choice of fluid (crystalloid or colloid) depends on the underlying cause of hypoperfusion and the patient's individual needs 5.
- Vasoactive agents, such as norepinephrine and dobutamine, may be used to support blood pressure and cardiac function 7.
- The use of inotropes and vasopressors should be guided by hemodynamic monitoring and clinical judgment, with the goal of optimizing cardiac output and tissue perfusion 7.
Fluid Resuscitation
- Fluid resuscitation should be initiated promptly in patients with global hypoperfusion, with the goal of restoring adequate blood pressure and perfusion of vital organs 3, 4, 5, 6.
- The choice of fluid (crystalloid or colloid) depends on the underlying cause of hypoperfusion and the patient's individual needs 5.
- Hypertonic saline solution may be used in patients with severe hypovolemia, as it has been shown to be effective in restoring hemodynamic parameters 3.
Vasoactive Agents
- Norepinephrine is a reasonable first-line agent for restoring blood pressure in patients with cardiogenic shock 7.
- Dobutamine is the first-line inotrope agent when norepinephrine fails to restore perfusion 7.
- Levosimendan can be used as a second-line agent or preferentially in patients previously treated with beta-blockers 7.
