Anesthesia, Local Anesthesia
Conditions
Brief summary
With blocks of lumbar and lumbar plexus, we can reduce the intravenous anesthetics usage. To offer an satisfied surgery process for patients, a proper sedation is necessary. So in this study, we want to investigate the influence of two different sedative drugs on outcomes of patients received hip replacement surgery .
Interventions
For patients in Group P, the sedation was achieved with a target-controlled infusion (TCI) of propofol, and the effect site concentration was set to 0.8-1.0μg/ml.
For patients in Group D, the sedation was achieved with a bolus of dexmedetomidine at 1.0 μg/kg (over a period of 15 to 20 min) and followed by an infusion of dexmedetomidine at 0.2-0.7 μg/kg/h. The depth of sedation was considered enough when patient was unresponsive to voice.
