Effect of intrathecal fentanyl on dexmedetomidine requirement for sedation during spinal anesthesia: a randomized controlled trial.
BACKGROUND Adequate sedation during spinal anesthesia requires careful titration to avoid hemodynamic instability and respiratory complications. We hypothesized that intrathecal fentanyl, used as an adjunct to neuraxial anesthesia, would reduce dexmedetomidine requirements for conscious sedation. This study evaluated t...
