Comparison in Frequency of Hypotension Between Remimazolam and Propofol in Hip Surgery

Patients receive remimazolam at a rate of 1 mg/kg/hr. When a patient's MOAA/S reaches 3 or less, the rate of remomazolam is maintained at a rate between 0.3 mg/kr/hr and 1.0 mg/kg/hr until the end of surgery.

Patients are administered propofol with an effect-site concentration of 1.0 mcg/mL to 2.5 mcg/mL by target controlled infusion.
