	Group R (n = 46)	Group RD (n = 46)	Z	p-value
T0	2.00 ± 0.00	2.02 ± 0.15	-1.000	0.317
T1	2.09 ± 0.29	2.78 ± 0.51	-6.309	< 0.001
T2	1.93 ± 0.25	2.26 ± 0.54	-3.590	< 0.001
T3	1.98 ± 0.15	2.57 ± 0.24	-5.839	< 0.001
T4	1.96 ± 0.21	2.65 ± 0.57	-6.309	< 0.001

Data are expressed as mean ± SD; statistical analysis was conducted using Mann-Whitney U test; Group R, ropivacaine group; Group RD, ropivacaine with dexmedetomidine group; T0, before anesthesia; T1, 15 min after EA; T2, fetal delivery; T3, uterus suture; T4, peritoneal closure. Ramsay Sedation Scale: 1, patient anxious and agitated or restless or both; 2, patient co-operative, orientated, and tranquil; 3, drowsiness but can respond to instructions; 4, brisk response; 5, a sluggish response; and 6, no response. p < 0.05 was considered statistically significant
