Results

A total of 90 patients were recruited in this study, and no patients withdrew. There were no significant differences among the three groups with regard to characteristics of patient, duration of surgery, and intra-operative sufentanil requirement (Table 1).

Among the three groups, there was no significant difference in CRBD severity at the first assessment in the PACU and 0.5 h postoperatively. However, the mild severity of CRBD was reduced in group C compared with that in groups A (P = 0.002) and B (P = 0.046) at 1 h (P = 0.008 among the three groups). The incidence of CRBD was lower in group C compared with that in groups A (P = 0.024) and B (P = 0.01) at 2 h (P = 0.012 among the three groups). The severity of CRBD was reduced in groups C (P = 0.005) and B (P = 0.008) compared with that in group A at 2 h (P = 0.005 among the three groups). The incidence of CRBD was reduced in group C compared with that in group A (P = 0.005) at 6 h (P = 0.013 among the three groups) (Table 2). VAS was reduced in group C compared with that in groups A and B at all time intervals (Figure 1). There was no difference in adverse effects among the three groups (Figure 2).
