Our objective was to characterize the impact of common initial sedation practices on invasive mechanical ventilation (IMV) duration and in-hospital outcomes in patients with acute brain injury (ABI) and to elucidate variations in practices between high-income and middle-income countries. ⋯ In an international registry of patients with ABI requiring IMV, IMV duration did not differ significantly relative to initial sedation strategy. However, patients started on midazolam had longer ICU stay.

Paroxysmal sympathetic hyperactivity (PSH) occurs with high prevalence among critically ill patients with traumatic brain injury (TBI) and is associated with worse outcomes. The PSH-Assessment Measure (PSH-AM) consists of a Clinical Features Scale and a diagnosis likelihood tool (DLT) intended to quantify the severity of sympathetically mediated symptoms and the likelihood that they are due to PSH, respectively, on a daily basis. Here, we aim to identify and explore the value of dynamic trends in the evolution of sympathetic hyperactivity following acute TBI using elements of the PSH-AM. ⋯ This study adds to the sparse research characterizing the heterogeneous temporal trends of sympathetic nervous system activation during the acute phase following TBI. This may open avenues for early identification of at-risk patients to receive tailored interventions to limit secondary brain injury associated with autonomic dysfunction and thereby improve outcomes in patients with TBI.
