Safety and efficacy comparison of remimazolam and propofol for intravenous anesthesia during gastroenteroscopic surgery of older patients: A meta-analysis

Figure 4 Forest plots of secondary outcomes after administration of remimazolam or propofol. A: The forest plot of the time to discharge after administration of remimazolam or propofol. Only two studies provided comprehensive information regarding the time to discharge, we found that compared to propofol group, elderly patients who were injected with remimazolam have the shorter discharge time, weighted mean difference equals -0.58; B: The forest plot of the time to fully alert after administration of remimazolam or propofol. A total of three cohort studies investigated which revealed that the time for patients to be fully alert after remimazolam sedation and that after propofol sedation without statistical significance P = 0.998; C: The forest plot of the successful sedation rate after administration of remimazolam or propofol. A total of six cohort studies investigated the successful sedation rate, and pooled analysis showed 96%.
