Clonidine Versus Midazolam for Premedication

March 18, 2008 updated by: University Hospital Schleswig-Holstein

Effects of Clonidine and Midazolam Premedication on Bispectral Index and Recovery After Elective Surgery

alpha2-agonists like clonidine offer several useful effects that make these drugs an interesting alternative to benzodiazepines for pharmacological premedication. We therefore sought to determine the effect of pre-anesthetic medication with clonidine vs. midazolam in a randomized, double-blind, placebo controlled study. Effects of pre-anesthetic medication were assessed on (1) bispectral index (BIS),(2) sedation score and visual analog scales for anxiety and pain, (3) neuropsychologic tests to assess cognitive function and (4) circulating stress hormones.
