Purpose: The incidence and the clinical presentation of neurological manifestations of coronavirus disease-2019 (COVID-19) remain unclear No data regarding the use of neuromonitoring tools in this group of patients are available Methods: This is a retrospective study of prospectively collected data The primary aim was to assess the incidence and the type of neurological complications in critically ill COVID-19 patients and their effect on survival as well as on hospital and intensive care unit (ICU) length of stay The secondary aim was to describe cerebral hemodynamic changes detected by noninvasive neuromonitoring modalities such as transcranial Doppler, optic nerve sheath diameter (ONSD), and automated pupillometry Results: Ninety-four patients with COVID-19 admitted to an ICU from February 28 to June 30, 2020, were included in this study Fifty-three patients underwent noninvasive neuromonitoring Neurological complications were detected in 50% of patients, with delirium as the most common manifestation Patients with neurological complications, compared to those without, had longer hospital (36 8 ± 25 1 vs 19 4 ± 16 9 days, p < 0 001) and ICU (31 5 ± 22 6 vs 11 5±10 1 days, p < 0 001) stay The duration of mechanical ventilation was independently associated with the risk of developing neurological complications (odds ratio 1 100, 95% CI 1 046-1 175, p = 0 001) Patients with increased intracranial pressure measured by ONSD (19% of the overall population) had longer ICU stay Conclusions: Neurological complications are common in critically ill patients with COVID-19 receiving invasive mechanical ventilation and are associated with prolonged ICU length of stay Multimodal noninvasive neuromonitoring systems are useful tools for the early detection of variations in cerebrovascular parameters in COVID-19
