Arousal time (min)	11.54 ± 2.07	11.38 ± 2.13	0.15
Extubation quality score (score)	1.45 ± 1.03	3.75 ± 1.12	<0.01
Postoperative period
Hypertension (n (%))	14 (22.6)	21 (35.0)	0.23
Tachycardia (n (%))	15 (24.2)	32 (53.3)	0.02
Cough (n (%))	17 (27.4)	30 (50.0)	0.04
Agitation (n (%))	9 (14.5)	17 (28.3)	0.17

Note. Patients in the TEAS group received electroacupuncture stimulation of bilateral Hegu (LI4), Neiguan (PC6), Lieque (LU7), and Chize (LU5) acupoints from 30 min before anesthesia to the end of surgery. Patients in the control group did not receive stimulation. TEAS: transcutaneous electrical acupoint stimulation; PONV: postoperative nausea and vomiting.
