[Acute blood purification for septic multiple organ failure]

Area of Science:

• Critical Care Medicine
• Nephrology
• Sepsis Pathophysiology

Background:

• Blood purification is crucial for managing septic multiple organ failure (MOF).
• Continuous renal replacement therapy (CRRT) aids in fluid, electrolyte, and acid-base balance, and waste removal.
• Continuous plasma exchange (CPE) with CRRT serves as artificial liver support for septic hepatic failure.

Purpose of the Study:

• To review the applications of various blood purification techniques in treating septic MOF.
• To highlight the role of direct hemoperfusion with polymyxin B immobilized fiber (PMX-DHP) in improving circulation and reducing cytokines.
• To emphasize the importance of matching blood purification strategies to the underlying causes of MOF.

Main Methods:

• Review of existing literature on blood purification in septic MOF.
• Discussion of continuous renal replacement therapy (CRRT) and continuous plasma exchange (CPE).
• Examination of direct hemoperfusion with polymyxin B immobilized fiber (PMX-DHP) and its proposed mechanism involving endogenous cannabinoid adsorption.

Main Results:

• CRRT effectively manages physiological balance and waste products in MOF.
• CPE combined with CRRT offers support for septic hepatic failure.
• PMX-DHP demonstrates rapid improvements in circulation and reduced cytokine levels, potentially via cannabinoid adsorption.

Conclusions:

• The choice of blood purification for septic MOF should be guided by the specific pathophysiological causes.
• A combination of therapies may be necessary for comprehensive management.
• Further research into mechanisms like cannabinoid adsorption by PMX-DHP is warranted.
