A randomized pilot study of electro-acupuncture treatment for hysterosalpingography pain relief and related anxiety

Abstract

Objective: To investigate the effect of acupuncture on reducing pain and anxiety related to hysterosalpingography (HSG). Materials and Methods: A total of 107 patients planned to undergo HSG were randomly separated into 3 groups; the acupuncture group (n=36), intramuscular diclofenac sodium group (n=35), and control group (n=37). In the acupuncture group, electro-acupuncture was applied to specified points for 20 mins before the procedure. In the intramuscular diclofenac sodium group, an intramuscular injection of 75 mg diclofenac sodium was applied 30 mins before the procedure. No analgesics were administered to the patients in the control group before intervention. Pain was evaluated with a Visual Analog scale (VAS) and anxiety with the State-trait Anxiety inventory-state (STAI-S), preoperatively and at specified times postoperatively. Results: The VAS scores at 1 and 5 minutes after HSG were similar in acupuncture group and intramuscular diclofenac sodium group, and significantly lower than in the control group. At 30 mins postoperatively, there was no significant difference between the 3 groups in respect of the VAS scores. The STAI-S scores at 1 hour preoperatively were similar in all the groups (p=0.563). In the comparisons of the STAI-S values at preoperative 5 mins, following acupuncture in acupuncture group and the diclofenac injection in intramuscular diclofenac sodium group, and at postoperative 30 mins, the acupuncture group values were determined to be statistically significantly lower than those of the other groups (p<0.001, p<0.001). Conclusion: Acupuncture has similar effects on the reduction of pain as other analgesics and reduces anxiety. It can therefore be used in HSG in suitable clinics.
