Peripheral Perfusion vs Standard Management in Sepsis/Septic Shock: A Prospective Randomized ED Study.
Summary
In a single-center randomized ED trial (n=200), sepsis/septic shock patients managed to a peripheral perfusion index target (>1.4) had significantly lower 30-day mortality versus standard SSC-guided care. Lactate clearance improved with PPI-guided resuscitation, while hospital and ICU lengths of stay were similar between groups.
Key Findings
- PPI-targeted management reduced 30-day mortality compared with standard SSC-guided care (p = 0.03).
- Lactate clearance was significantly better in the PPI group (p < 0.001).
- No significant differences in hospital or ICU length of stay were observed (p = 0.26 and p = 0.68).
Clinical Implications
Incorporating PPI-guided targets into early sepsis resuscitation may improve survival. Implementation will require bedside PPI monitoring, staff training, and protocol integration alongside MAP and lactate metrics.
Why It Matters
This pragmatic RCT demonstrates mortality benefit from targeting microcirculation (PPI) rather than exclusively macro-hemodynamics, potentially shifting resuscitation strategies in early sepsis.
Limitations
- Single-center design may limit generalizability.
- Blinding was not feasible and trial registration/reporting details were not provided in the abstract.
Future Directions
Multicenter, pre-registered RCTs should validate mortality benefit, assess adverse events, and test implementation strategies and cost-effectiveness of PPI-guided resuscitation.
