ABSTRACT
OBJECTIVE:
The current definition of delayed cerebral ischemia (DCI) is based on clinical characteristics precluding its use in patients with poor-grade subarachnoid hemorrhage (SAH). Additional concepts to evaluate the unconscious patient are required. Invasive neuromonitoring (INM) may allow timely detection of metabolic and oxygenation crises before irreversible damage has occurred.METHODS:
The authors present a cohort analysis of all consecutive SAH patients referred to a single tertiary care center between 2010 and 2018. The cohort (n = 190) was split into two groups one before (n = 96) and one after (n = 94) the introduction of INM in 2014. A total of 55 poor-grade SAH patients were prospectively monitored using parenchymal oxygen saturation measurement and cerebral microdialysis. The primary outcome was the Glasgow Outcome Scale-Extended (GOSE) score after 12 months.RESULTS:
With neuromonitoring, the first DCI event was detected earlier (mean 2.2 days, p = 0.002). The overall rate of DCI-related infarctions decreased significantly (from 44.8% to 22.3%; p = 0.001) after the introduction of invasive monitoring. After 12 months, a higher rate of favorable outcome was observed in the post-INM group, compared to the pre-INM group (53.8% vs 39.8%), with a significant difference in the GOSE score distribution (OR 4.86, 95% CI -1.17 to -0.07, p = 0.028).CONCLUSIONS:
In this cohort analysis of poor-grade SAH patients, the introduction of INM and the extension of the classic DCI definition toward a functional dimension resulted in an earlier detection and treatment of DCI events. This led to an overall decrease in DCI-related infarctions and an improvement in outcome.Palavras-chave
