Results
Baseline characteristics and hemodynamic variables did not differ
between the two groups (all p>0.05). In 8/23 (35%)
patients propofol infusion velocity reduction was necessary to maintain
the hemodynamic values, compared to 7/26 (27%) with dexmedetomidine.
Inter-group comparison of hemodynamic variables during the procedure
showed no statistically significant difference, despite a trend in favor
of dexmedetomidine (3 respiratory depressions and 3 persistent
hypotension episodes with propofol vs. 0 with dexmedetomidine; p =
0.057).
