The sedation efficacy of different doses of remimazolam in elderly patients with regional nerve block anaesthesia

The results indicated that doses of 5-5.5 mg remimazolam are more suitable for sedation in elderly patients, and the loss of consciousness time and depth of sedation differed according to the remimazolam dosage. Doses of 5-5.5 mg remimazolam were associated with adequate levels of sedation in elderly patients and with a decreased risk of complications, whilst haemodynamic fluctuations occurred approximately 12-15 min after the administration of remimazolam.
