Study on the Analgesic Effect and Mechanism of Percutaneous Acupoint Electrical Stimulation Combined with Routine Analgesia on Uterine Contraction Pain after Painless Abortion
Objective:To investigate the analgesic effect and mechanism of percutaneous acupoint electrical stimulation combined with routine analgesia on uterine contraction pain after painless abortion.Methods:100 patients were selected to receive painless abortion in our hospital.According to random number table method who were divided into two groups.The control group received routine post-operative analgesia treatment,and at the same time,electrodes were affixed to the most acid swelling of Neiguan,Hegu and Sanyin Jiao,but acupuncture point stimulation was not possible.The observation group was treated with percutaneous acupoint electrical stimulation on the basis of routine postoperative analgesia.The general body conditions of the two groups at different time points,the pain and pain of the two groups at different time points,the score of positive and negative emotion scale at T3,the level of serum substance P,prostaglandin,5-hydroxytryptamine,β-endorphin and dykephalin at T3,the score of psychological state and the score of satisfaction at T4 were compared.Results:The BP,HR,RR,SpO2 at T1 and T2 points in control group were significantly lower than T0 points in the same group,and there was no statistical significance in BP,HR,RR,SpO2 at T3 points in control group and T0 points in observation group(P＞0.05).BP,HR,RR and SpO2 in control group were significantly lower than those in observation group at T1 and T2(P＜0.05).At T0,there was no statistical significance in VAS scores between the two groups(P＞0.05).At T1,T2 and T3 points,VAS scores in the observation group were significantly lower than those in the control group(P＜0.05).The VAS scores at T1 and T2 points in the control group were significantly higher than those at T0 points in the same group,and the VAS scores at T1,T2 and T3 points in the observation group were significantly lower than those at T0 points(P＜0.05).The positive emotion of the observation group was significantly higher than that of the control group,and the negative emotion was significantly lower than that of the control group(P＜0.05).The serum levels of Substance P,prostaglandin,5-hydroxytryptamine,β-endorphin and dynorphin in the observation group were significantly lower than those in the control group(P＜0.05).The psychological status score of the observation group was significantly lower than control group,and the satisfaction score was significantly higher than control group(P＜0.05).Conclusion:Percutaneous acupoint electrical stimulation combined with routine analgesia can significantly improve the analgesic effect,psychological state and satisfaction of patients after pain-less abortion,which may be related to the reduction of serum substance P,prostaglandin,5-hydroxytryptamine,β-endorphin and dynor-phin levels.
