Hemodynamic Safety and Effect of Dexmedetomidine on Superficial Cervical Block Quality for Carotid Endarterectomy: A Prospective Study
Authors' conclusion
The addition of 50 μg of dexmedetomidine to 0.5% levobupivacaine and 2% lidocaine for SCB did not influence the hemodynamics and frequency of adverse effects. The median sensory block duration time showed no statistical difference between the groups, but the quality of analgesia postoperatively was much improved in the study group.

Primary result
As reported in the abstract
Onset and duration of sensory block and analgesia
- Time to first analgesia longer in the intervention group than control
- No difference in duration of sensory block between groups
- Log-rank test: significant difference in probability of NRS <3
Safety
- Minimum effects on hemodynamic parameters
- No differences in incidence of adverse effects
