The role of diuretics in ICUs: when? which? how?

Area of Science:

• Critical Care Medicine
• Pharmacology
• Nephrology

Background:

• Diuretic agents are frequently used in intensive care units (ICUs) for diverse clinical indications.
• Significant uncertainties persist regarding optimal diuretic use in ICUs, including indications, pharmacokinetics, dosing, and safety.

Purpose of the Study:

• To review current evidence on diuretic agents in the ICU setting.
• To clarify indications, pharmacodynamics, pharmacokinetics, and safety of diuretics in critical illness.
• To assess the impact of organ failure on diuretic efficacy and to review recent clinical trials.

Main Methods:

• Systematic review of recent clinical trials, large registries, and existing literature.
• Analysis of drug behavior changes during critical illnesses and organ failures.
• Assessment of diuretic utility across different organ failure states.

Main Results:

• Recent studies have provided new insights into diuretic use in ICUs.
• Understanding drug behavior changes in critical illness is essential for effective diuretic therapy.
• Diuretic effectiveness varies significantly with the type of organ failure present.

Conclusions:

• Individualized diuretic strategies are paramount in managing critically ill patients.
• This review synthesizes current knowledge to guide diuretic selection, dosing, and monitoring in ICUs.
• Addressing knowledge gaps in diuretic use can optimize patient outcomes and safety.
