Early persistent exposure to high CVP is associated with increased mortality and AKI in septic shock: A retrospective study - 20/11/23
Abstract |
Purpose |
This study's objective was to investigate the association between exposure to different intensities of central venous pressure (CVP) over time in patients with septic shock with 28-day mortality and acute kidney injury (AKI).
Materials and methods |
We obtained data from the AmsterdamUMCdb, which includes data on patients ≥18 years old with septic shock undergoing CVP monitoring. The primary outcome was mortality by day 28. Piecewise exponential additive mixed models were used to estimate the strength of the association over time.
Results |
9668 patients were included in the study. They exhibited 8.2% overall mortality at 28 days and 41.1% AKI incidence. Daily time-weighted average CVP was strongly associated with increased mortality at 28 days, primarily within 24 h of ICU admission. The mortality rate of patients was lowest when the CVP was 6–12 cmH2O. When the time of high CVP (TWA-CVP >12 cmH2O) exposure within the first 24 h was >5 h, the risk of death increased by 2.69-fold. Additionally, patients exposed to high CVP had a significantly increased risk of developing AKI.
Conclusions |
The optimal CVP range for patients with septic shock within 24 h of ICU admission is 6–12 cmH2O. Mortality increased when patients were exposed to high CVP for >5 h.

• | The optimal CVP range for septic shock within 24 h of ICU admission is 6–12 cmH2O. |
• | Mortality increased significantly when patients were exposed to high CVP > 5 h. |
• | High CVP exposure significantly increased AKI, which indirectly increased mortality. |
