Aim This study aimed to evaluate the optimal combination of parameters for the management of pain during surgical abortion using transcutaneous acupoint electrical stimulation (TEAS). Methods This study recruited patients scheduled for surgical abortion between October 2014 and August 2015. The treatment protocol was created using three levels for each factor (stimulating time, acupoints, age, and parity). The primary outcomes were intraoperative visual analog scale (VAS), postoperative VAS, cervical relaxation degree and intraoperative blood loss. The secondary outcomes were the vital signs. Results Stimulation time was associated with intraoperative VAS scores ( P < 0.001), acupoints were associated with postoperative VAS scores ( P = 0.037), and age was associated with postoperative VAS scores ( P < 0.043). Parity ( P = 0.025) was associated with heart rate. A comprehensive analysis of the parameters revealed the best levels for each (stimulation time: from 15 min before operation to immediate postoperative; acupoints: SP 6 and LR 3; patient age 25.1–30.0 years; and parity: G ≥2 P 0 A ≥1 ). Seven patients did not complete follow‐up. The remaining 135 subjects did not show continuous vaginal bleeding, abdominal pain, fever or any other adverse effect. Conclusion During surgical abortion, TEAS stimulation from 15 min before operation to immediate postoperative, SP 6 and LR 3, age 25.1–30.0 years and G ≥2 P 0 A ≥1 were associated with the best analgesic effect.
