Summary
This summary is machine-generated.Early initiation of polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) in cancer patients with septic shock improves survival. This treatment reduces in-hospital mortality and enhances lactate clearance, particularly when started within 3 hours.
Area Of Science
- Critical Care Medicine
- Oncology
- Nephrology
Background
- Refractory septic shock in cancer patients presents a significant challenge with high in-hospital mortality.
- Polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) is a potential treatment for septic shock.
- The optimal timing for PMX-DHP initiation in this patient population remains under investigation.
Purpose Of The Study
- To investigate the correlation between the timing of PMX-DHP initiation and in-hospital mortality in cancer patients with refractory septic shock.
- To analyze hemodynamic changes and organ function markers in relation to PMX-DHP timing.
Main Methods
- Retrospective analysis of 46 cancer patients with refractory septic shock treated with PMX-DHP.
- Patients were divided into early (≤3 hours) and late (>3 hours) PMX-DHP initiation groups.
- Comparison of vasopressor inotropic score (VIS), Sequential Organ Failure Assessment (SOFA) score, and lactate clearance before and 24 hours post-PMX-DHP.
Main Results
- Overall in-hospital mortality was 52.17%, with a lower rate in the early initiation group.
- Both groups showed decreases in VIS and SOFA scores, with greater lactate clearance improvement in the early group.
- Multivariable analysis identified reduced SOFA score and early PMX-DHP initiation as key factors for reduced mortality risk.
Conclusions
- Early initiation of PMX-DHP (within 3 hours) in cancer patients with refractory septic shock is associated with reduced in-hospital mortality.
- Early PMX-DHP improves lactate clearance and overall survival in this critically ill population.
- Timing of PMX-DHP is a crucial factor influencing outcomes in cancer patients with refractory septic shock.
