Comparison of SVRI.

Eligible patients were randomized into either the "propofol group" (group P, n = 29) or the "remimazolam group" (group R, n = 28). SVRI in both groups were normally distributed, expressed as mean ± standard deviation, and statistically analyzed using Student's t-tests. ^*P < 0.05, compared with the group P. Abbreviations: T₀, after the patient entered the operation room and rested for at least 15 min; T₁, BIS value decreased to 60 after the initiation of induction; T₂, 4 min after administration of cis-atracurium; T₃, 5 min after endotracheal intubation; SVRI, systemic vascular resistance index.
