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 7 The recalled Arabic numbers at T₀, T₁, T₂, T₃, T₄, and T₅ in the two groups. The recalled Arabic numbers were lower at T₁ and T₂ in the PR group and at T₁ in the PRD group compared to T₀ (P < 0.001). The number of recalled Arabic numbers was lower at T₂ in the PR group than in the PRD group (P < 0.001)
