      Benzodiazepines bind to an allosteric site on the neuronal GABAA receptor, a ligand-gated chloride channel, and enhance chloride conductance to hyperpolarize the neuronal membrane, thus augmenting inhibitory…

      Status epilepticus (SE) is a true neurologic emergency (1). Both convulsive and nonconvulsive SE affect people of all ages, although it is more common and carries greater…
