Safety and Efficiency of Combined Extracorporeal Blood Purification in Neurosurgical ICU. Prospective RCT

Not Applicable
Conditions
Septic Shock
Interventions
Procedure: Combined extracorporeal blood purification
Procedure: CRRT
Registration Number
NCT04152174
Lead Sponsor
Burdenko Neurosurgery Institute
Brief Summary

To assess the efficiency and safety of combined extracorporeal blood purification in patients with septic shock in Neurosurgical ICU in comparison with the efficiency and safety of the continuous renal replacement therapy (CRRT).

Detailed Description

According to studies and modern sepsis treatment guidelines, conventional CRRT has not proved effective in the septic shock treatment.

Effectiveness of other extracoporeal blood purification methods, such as hemoadsorption or combined blood purification (hemoadsorption combined with CRRT) is widely pointed out in current publications: contemporary studies in general ICU patients demonstrated that the use of hemoadsorption or combined extracorporeal blood purification methods is effective for septic shock patients treatment.

It has been proven that cytokines discharged into the systemic blood flow are the key pathophysiological mechanism of septic shock. Hemoadsorption allows for significantly more effective removal of different inflammatory mediators than the traditional methods of CRRT. The combined extracorporeal blood purification method demonstrated similar efficacy in general ICU patients.

The aim of this study is to assess the efficiency and safety of combined extracorporeal blood purification in with septic shock in neurosurgical ICU in comparison with the efficiency and safety of the continuous renal replacement therapy (CRRT) with AN69 membrane.

Study novelty: We have not encountered published studies evaluating the efficiency of combined extracorporeal blood purification methods in neurosurgical patients with septic shock. Furthermore, currently there is not enough data to compare combined extracorporeal blood purification with CRRT for septic shock treatment. The planned study is the first to investigate the safety and efficiency of combined extracorporeal blood purification in patients with septic shock in neurosurgical ICU.
