Study on the combination of remazolam besylate and sufentanil in elderly patients with percutaneous vertebroplasty.

This study analyzed the application effect of remimazolam besylate combined with sufentanil on percutaneous vertebroplasty (PVP). Forty elderly patients with osteoporotic vertebral compression fractures (OVCF) were randomly divided into sufentanil (A group) and remimazolam besylate + sufentanil groups (B group). A group was given sufentanil anesthesia, B group was given remimazolam besylate combined with sufentanil anesthesia. Heart rate (HR), mean arterial pressure (MAP), saturation of pulse oxygen (SpO2) and Ramsay sedation score were recorded at different time points, including T0 (before administration), T1 (beginning of surgery), T2 (perfusion of bone cement) and T3 (end of surgery). HR, MAP, SpO2 were continuously monitored by electrocardiogram monitor. The visual analogue scale (VAS) pain scores of the two groups were recorded at before anesthesia and immediately after surgery. The adverse reactions (AR) were observed, including respiratory depression, nausea and vomiting, and restlessness during the recovery period. Compared with group A, MAP was increased at T2 and T3 time points in group B. Ramsay sedation scores at T2 time points in group B were higher than that in group A. The VAS score of immediately after operation and incidence of AR of group B was lower than that of group A. In elderly patients undergoing PVP, remimazolam besylate combined with sufentanil has no obvious effect on patients' respiratory parameters, with clear analgesic and sedative effects and low incidence of AR, which is worthy of promotion.
