Clinical Scorecard: Relationship of Pulse Pressure Measurements with Mortality Outcomes in Septic Shock Patients: A Retrospective Cohort Analysis
At a Glance
Category
Detail
Condition
Septic Shock
Key Mechanisms
Pulse Pressure (PP) reflects cardiac output and vascular elasticity, indicating hemodynamic status beyond mean arterial pressure (MAP).
Target Population
Adult septic shock patients requiring vasoactive drugs to maintain MAP ≥ 65 mmHg after fluid resuscitation.
Care Setting
Intensive Care Unit (ICU) during early resuscitation phase
Key Highlights
Maintaining PP between 40 and 70 mmHg during the first 24 hours in ICU is associated with significantly lower 28-day mortality in septic shock patients.
Age modifies the PP-mortality relationship: elderly patients (>65 years) have higher mortality risk with PP > 70 mmHg, while younger patients (≤65 years) have higher risk with PP < 40 mmHg.
Both low (<40 mmHg) and high (>70 mmHg) PP24h are independent risk factors for 28-day mortality based on multivariate logistic regression.
Guideline-Based Recommendations
Diagnosis
Diagnose septic shock by sepsis with organ failure score ≥ 2, requiring vasoactive drugs to maintain MAP ≥ 65 mmHg, and serum lactate > 2 mmol/L after fluid resuscitation.
Management
Target pulse pressure within 40–70 mmHg during early resuscitation to improve survival outcomes.
Consider patient age when managing PP targets: avoid PP > 70 mmHg in elderly and PP < 40 mmHg in younger patients.
Monitoring & Follow-up
Monitor invasive systolic and diastolic blood pressure hourly to calculate PP24h during the first 24 hours in ICU.
Use PP24h as a hemodynamic parameter alongside MAP to guide resuscitation.
Risks
PP24h values outside 40–70 mmHg range increase 28-day mortality risk.
Elderly patients are at increased risk with high PP24h (>70 mmHg), younger patients with low PP24h (<40 mmHg).
Patient & Prescribing Data
Adult septic shock patients admitted to ICU requiring vasoactive support.
Maintaining PP24h within 40–70 mmHg during early resuscitation correlates with improved 28-day survival; age-specific PP targets may optimize outcomes.
Clinical Best Practices
Incorporate pulse pressure monitoring into hemodynamic assessment during septic shock resuscitation.
Adjust hemodynamic management strategies based on patient age to avoid PP extremes.
Use propensity score matching and multivariate analysis to identify independent risk factors in clinical data.
Invited narrative review supports early, interprofessional rehabilitation across the ICU recovery continuum while emphasizing heterogeneous evidence and inconsistent implementation worldwide.
