Abstract<\/h2>\n
\n
Septic shock<\/a>\u00a0leads to progressive hypoperfusion and\u00a0tissue hypoxia<\/a>. Unfortunately, numerous uncertainties exist around the best monitoring strategy, as available techniques are mere surrogates for these phenomena. Nevertheless, central venous\u00a0oxygen saturation<\/a>\u00a0(ScvO2<\/sub>), venous-to-arterial CO2<\/sub>\u00a0gap, and lactate normalization have been fostered as resuscitation targets for septic shock. Moreover, recent evidence has challenged the central role of lactate. Following the ANDROMEDA-SHOCK trial, capillary refill time (CRT) has become a promissory target, considering the observed benefits in mortality, treatment intensity, and organ dysfunction. Interpretation of CRT within a multimodal approach may aid clinicians in guiding resuscitative interventions and stop resuscitation earlier, thus avoiding the risk of morbid\u00a0fluid overload<\/a>. Integrative assessment of a patient’s perfusion status can be easily performed using bedside clinical tools. Based on its fast kinetics and recent supporting evidence, targeting CRT (within a holistic assessment of perfusion) may improve outcomes in septic shock resuscitation.<\/div>\n

Key Points<\/strong><\/p><\/blockquote>\n

    \n
  1. Septic Shock Pathophysiology<\/strong>: Characterized by acute circulatory failure, leading to inadequate oxygen utilization and systemic hypoperfusion.<\/li>\n
  2. Lactate as a Marker<\/strong>: Persistent hyperlactatemia indicates poor prognosis but lacks specificity as it may result from stress-related hypermetabolism rather than hypoperfusion.<\/li>\n
  3. CRT as a Resuscitation Target<\/strong>: CRT\u2019s faster kinetics and bedside applicability make it a promising alternative to lactate, supported by the ANDROMEDA-SHOCK trial.<\/li>\n
  4. ANDROMEDA-SHOCK Findings<\/strong>: CRT-targeted resuscitation reduced mortality (34.9% vs. 43.4%) and organ dysfunction compared to lactate-targeted approaches.<\/li>\n
  5. Hemodynamic Coherence<\/strong>: Early resuscitation efforts should aim to restore macrocirculation and microcirculation coherence, as late-stage interventions may worsen outcomes.<\/li>\n
  6. Fluid Overload Risks<\/strong>: Over-resuscitation increases mortality risk, emphasizing the importance of stopping resuscitation once adequate perfusion is restored.<\/li>\n
  7. Multimodal Monitoring<\/strong>: Combining CRT with other markers, such as ScvO\u2082 and venous-to-arterial CO\u2082 gap, enhances diagnostic accuracy and patient-specific intervention.<\/li>\n
  8. Peripheral Perfusion Tools<\/strong>: CRT and mottling score offer valuable prognostic insights and guide interventions, especially in resource-limited settings.<\/li>\n
  9. Dynamic Monitoring<\/strong>: Real-time perfusion assessments, including CRT responsiveness to fluid challenges, inform timely and appropriate resuscitation strategies.<\/li>\n
  10. Future Directions<\/strong>: Research is needed to refine CRT measurement techniques, explore optical technologies, and integrate CRT into routine pre-ICU and ED assessments.<\/li>\n<\/ol>\n
