[Systemic hemodynamics in constant hemofiltration in patients with septic shock]

Area of Science:

• Critical Care Medicine
• Nephrology
• Intensive Care

Background:

• Sepsis and shock trigger systemic inflammatory response syndrome (SIRS).
• Hemodiafiltration (HDF) is a therapeutic approach for SIRS, applicable even without renal failure.
• Systemic hemodynamics in septic shock patients require careful management.

Purpose of the Study:

• To evaluate the effects of HDF on systemic hemodynamics in patients with septic shock.
• To assess the impact of HDF on vasopressor requirements and patient outcomes.

Main Methods:

• Hemodiafiltration (HDF) was administered to 18 patients with septic shock, divided into two groups.
• Systemic hemodynamic parameters were monitored throughout the treatment period.
• Vasopressor dosages (dopamine, norepinephrine) were recorded and analyzed.

Main Results:

• HDF stabilized systemic hemodynamics in 50% of patients, improving key cardiovascular indicators.
• Significant reductions (3-fold) in initial dopamine and norepinephrine doses were observed by days 3-4.
• The other group experienced refractory shock, with high mortality (72.2%) primarily due to multiple organ dysfunction or delayed surgical intervention.

Conclusions:

• HDF demonstrates potential in stabilizing hemodynamics and reducing vasopressor support in septic shock patients.
• Despite challenges in refractory cases, HDF may facilitate survival through the critical illness phase.
• Further research is warranted to optimize HDF protocols for septic shock management.
