Key Points

This study investigates the relationship between hemodynamic parameters and mortality risk following spontaneous intracerebral hemorrhage.
Retrospective cohort study of 120 patients with spontaneous intracerebral hemorrhage admitted to an intensive care unit.
Continuous monitoring of intracranial pressure and other hemodynamic variables over 7,400 hours.
Multivariate Cox regression analysis to evaluate predictors of survival.
Elevated intracranial pressure identified as a significant predictor of reduced survival (p=0.001).
Higher systolic blood pressure and central venous pressure predicted improved survival (p=0.001, p=0.019 respectively).
Analysis showed greater ICP variability in smaller hemorrhages, which were associated with lower survival rates.

Abstract

Abstract Background and aims Spontaneous intracerebral haemorrhage (ICH) is associated with high morbidity and mortality. We investigated associations between cerebral and systemic haemodynamic parameters, including intracranial pressure (ICP), and mortality risk post-ICH in a UK intensive care unit (ITU). Methods This retrospective cohort included 120 patients ≥18 years old admitted to ITU between June 2013 and April 2019 with spontaneous ICH, who underwent continuous monitoring. Mean, standard deviation and variability independent of mean (VIM) were calculated for ICP and other haemodynamic variables in over 7,400 hours of data. Kruskal-Wallis tests assessed differences by ICH volume tertile and survival during monitoring (23 - 94.5 hours). Multivariate Cox regression evaluated predictors of survival. Results Eighty patients survived beyond 30 days; 40 died within 30 days; 27 died during the monitoring period. ICP VIM (p0.001) and mean arterial pressure VIM (p=0.017) were associated with ICH volume, with greater variability observed in smaller haemorrhages. Mean diastolic blood pressure (p=0.048) and mean heart rate (p=0.037) showed U-shaped associations with ICH volume (higher in the upper and lower tertiles). Cox regression identified elevated ICP (p=0.001) and female sex (p=0.019) as predictors of reduced survival. Higher central venous pressure (CVP) (p=0.019), systolic blood pressure (SBP) (p=0.001) and larger ICH (p=0.009) predicted improved survival. Conclusions In this cohort, a complex interplay of factors is observed, highlighted by analysis of ICH volume, whereby ICP variability was found to be significantly greater in smaller haemorrhages, which were associated with reduced survival. Higher CVP, SBP, and larger ICH volume were predictors of improved survival. Conflict of interest Jennifer Nicholls: nothing to disclose. Corry Gellatly: nothing to disclose.
