How I personalize fluid therapy in septic shock?

Area of Science:

• Critical Care Medicine
• Nephrology
• Cardiology

Background:

• Fluid therapy in septic shock aims to improve cardiac output and tissue oxygenation.
• Current fluid administration strategies have inconsistent efficacy and potential adverse effects.
• Personalized fluid management is crucial throughout circulatory failure stages.

Purpose of the Study:

• To advocate for personalized fluid therapy in septic shock.
• To guide fluid selection and administration based on patient characteristics and clinical status.
• To optimize fluid management strategies for improved patient outcomes.

Main Methods:

• Assessing preload responsiveness using tests like passive leg raising and mini-fluid challenge.
• Considering patient-specific factors such as mechanical ventilation and monitoring capabilities.
• Utilizing specific variables to assess fluid accumulation in conditions like ARDS and abdominal issues.

Main Results:

• Isotonic saline can induce hyperchloremic acidosis with large volumes; balanced solutions are suggested for patients with rising chloremia.
• Initial fluid resuscitation should account for absolute hypovolemia beyond patient weight.
• Preload responsiveness assessment is vital after initial fluid infusion, with test selection depending on clinical context.

Conclusions:

• Personalized fluid therapy, considering patient status and clinical situation, is essential in septic shock.
• Appropriate fluid selection and dynamic preload assessment optimize hemodynamic management.
• Fluid de-escalation guided by preload responsiveness is crucial in managing fluid accumulation.
