Question 1

How were the elderly patients assigned to study groups in this trial?

Accepted Answer

Forty elderly patients with osteoporotic vertebral compression fractures were randomly divided into group A (sufentanil anesthesia) and group B (remimazolam besylate combined with sufentanil anesthesia).

Question 2

Which outcomes were monitored during and after percutaneous vertebroplasty?

Accepted Answer

Heart rate, mean arterial pressure, pulse oxygen saturation, and Ramsay sedation scores were recorded at multiple time points (T0–T3), while VAS pain scores were measured before anesthesia and immediately after surgery. Adverse reactions such as respiratory depression, nausea/vomiting, and restlessness were observed during recovery.

Question 3

What were the key comparative findings between group B and group A?

Accepted Answer

Compared with group A, group B had higher MAP at T2 and T3 and higher Ramsay sedation scores at T2. Group B also showed a lower VAS score immediately after operation and a lower incidence of adverse reactions.
