The effects of remifentanil-propofol combined with dexmedetomidine on cognitive dysfunction in elderly patients after ureteroscopic holmium laser lithotripsy: a double-blind randomized controlled trial

Table 6 The State-Trait Anxiety Inventory scores at T₀, T₁, T₂, T₃, T₄, and T₅ in the two groups. The STAI scores were higher at T₁ and T₂ compared to T₀ in the PR group, and the STAI scores were higher at T₁ compared to T₀ in the PRD group. The STAI scores at T₁ and T₂ were lower in the PRD group compared to the PR group (P < 0.005)
