Continuous Rocuronium Yields Modest Intracranial Pressure Reductions

Managing severe traumatic brain injury and neurocritical illness requires aggressive intervention to prevent secondary neurological damage [1]. In the intensive care unit, clinicians routinely rely on a complex array of sedatives and anesthetics to maintain strict hemodynamic stability and control intracranial pressure [2, 3]. While continuous neuromuscular blockade (the administration of paralytic medications to halt skeletal muscle movement) is a well-established tool for managing severe respiratory failure [4], neurocritical care guidelines also recommend it as a secondary option for refractory intracranial hypertension, or dangerously high pressure within the skull. Despite this physiological rationale, the actual impact of systemic paralysis on brain pressure has remained poorly quantified in everyday clinical practice. A retrospective analysis of 106 patients receiving continuous rocuronium infusions now clarifies this effect, demonstrating that median intracranial pressure decreased from 20.7 to 18.6 mm Hg (a within-patient change of -0.9 mm Hg; p=0.017) and cerebral perfusion pressure (the net pressure gradient driving blood flow to the brain) increased from 71.1 ± 10.5 to 75.2 ± 12.5 mm Hg (p<0.001) [5].
