Dexmedetomidine on Post-operative Blood Pressure in Bain Arteriovenous Malformation Embolization
Dexmedetomidine on Post-operative Blood Pressure in Bain Arteriovenous Malformation Embolization
Aim of this trial is to study the effect of Dexmedetomidine on post-operative blood pressure
 in patients undergoing brain arteriovenous malformation embolization. The patients were
 randomized allocated to either Dexmedetomidine group or Control group. Patients in
 Dexmedetomidine group will receive intravenous Dexmedetomidine while the control group will
 receive normal saline. Post-operative anti-hypertensive drug, Visual analogue
 score,post-operative analgesics consumption, Quality of Recovery score, Ramsay score, and
 adverse events were recorded.

 randomized allocated to either Dexmedetomidine group or Control group according to a random
 number. Patients in Dexmedetomidine group will receive intravenous Dexmedetomidine while the
 control group will receive normal saline. Post-operative anti-hypertensive drug, Visual
 analogue score,post-operative analgesics consumption, Quality of Recovery score-15 items,
 Ramsay score, and adverse events were recorded.
