Goal-directed therapy: what is the goal again?

Area of Science:

• Anesthesiology
• Nephrology
• Critical Care Medicine

Background:

• Intraoperative hypotension (IOH) and hemodynamic instability are areas of increased focus.
• Increased awareness to limit IOH, coupled with fluid restriction and vasopressor use, correlates with a rise in postoperative acute kidney injury (AKI).
• Current literature advocates for enhanced intraoperative monitoring of mean arterial pressure (MAP), judicious fluid management, and appropriate vasopressor/inotropic support.

Purpose of the Study:

• To introduce an algorithm for managing IOH.
• To minimize iatrogenic harm by guiding anesthesia clinicians in selecting optimal interventions.
• To promote a comprehensive evaluation of IOH contributing factors.

Main Methods:

• Implementing a structured algorithm for IOH management.
• Focusing on individualized, goal-directed therapy.
• Evaluating contributing factors like fluid deficits, myocardial depression, and vasodilation.

Main Results:

• The algorithm guides clinicians to appropriate interventions at optimal times.
• Comprehensive evaluation of IOH causes is ensured.
• A shift towards individualized care may improve patient outcomes.

Conclusions:

• An algorithm-based approach to IOH management is proposed.
• Individualized, goal-directed therapy may enhance patient outcomes.
• Minimizing iatrogenic harm is a key objective in hemodynamic management.
