Randomized Controlled TrialBispectral index-guided intraoperative sedation with dexmedetomidine and midazolam infusion in outpatient cataract surgery.
This study aimed to evaluate the role of alfa-2 agonist infusion, with dexmedetomidine or midazolam, on hemodynamic and respiratory parameters while titrating the sedation level with the bispectral index (BIS) during cataract surgery. ⋯ Dexmedetomidine infusion mildly decreased heart rate in the later periods of surgery with better pain scores in the postoperative period. Dexmedetomidine should be an alternative for intraoperative sedation in outpatient cataract surgery.

Randomized Controlled Trial Comparative StudyRegional anesthesia for carotid endarterectomy: a comparison between ropivacaine and levobupivacaine.
This study compares ropivacaine and levobupivacaine when administered for cervical plexus block. The authors therefore compared the arterial pressure profile and the incidence of hypotension between drugs. ⋯ Levobupivacaine has a greater vasodilatory effect than ropivacaine. Its higher incidence of hypotension, although not statistically significant, suggests ropivacaine as the drug of choice for cervical plexus block.
