A recent study on the effects of commonly used anesthetic and sedative drugs on cerebrospinal fluid flow and volume has uncovered significant findings regarding their impact on the brain's vital glymphatic system. These findings may affect neuroanesthesia practices. Researchers found that two commonly used anesthetic regimens are stronger in regulating cerebrospinal fluid flow and cerebral blood volume than the influence of blood carbon dioxide. This finding may reshape neuroanesthesia practices in clinical settings, particularly in neurological, brain trauma, and neurosurgical scenarios, where manipulating carbon dioxide levels is routine for regulating cerebral blood flow, cerebral oxygenation, and intracranial pressure in intubated...
