Clinical Effect of Electroacupuncture on Postoperative Analgesia After Cesarean Sectionanalgesia After Cesarean Section
Condition: Cesarean Section
Study type: Interventional

Summary: 
      Cesarean section is one of the most common operations in obstetrics. A survey shows that the
      rate of cesarean section in China is more than 40%, and even more than 70%. At present, the
      main analgesia methods after cesarean section are: patient controlled intravenous analgesia
      (PCIA), single injection of opioids into spinal canal, nerve block technique, combined or
      single oral drug for postoperative analgesia, etc. All kinds of postoperative analgesia
      methods have their own advantages and disadvantages. At present, PCIA is widely used in
      clinic, but it can cause side effects such as pruritus, nausea, vomiting and respiratory
      depression. Therefore, it is urgent to find a safe, effective, economic, reliable and
      operable treatment of PCIA for postoperative analgesia after cesarean section.
      Electroacupuncture is a technology combining traditional acupuncture and modern
      electrotherapy, which has a significant effect on acute and chronic pain. Studies have
      confirmed that electroacupuncture can help parturient women to deliver and relieve pain after
      delivery. However, there are few studies on the analgesic effect of Electroacupuncture on
      pain after cesarean section, and there are a few reports on wrist ankle acupuncture. On the
      basis of our previous research, we found that the frequency of 20 / 100Hz and 2Hz were the
      best for EA analgesia, and the density wave. Electroacupuncture is an ideal choice for PCIA
      analgesia after cesarean section because of its low price, rapid onset, long duration and no
      adverse drug reactions. "Zusanli" belongs to the stomach meridian of Foot Yangming. It is the
      meridian of multi Qi and multi blood. It has the effect of regulating meridians and
      collaterals, dredging Qi and blood, and treating various kinds of abdominal pain. Sanyinjiao
      belongs to the spleen meridian of foot Taiyin, which is the meeting of foot Taiyin, Jueyin
      and Shaoyin. Since ancient times, Sanyinjiao has been a commonly used acupoint to relieve
      labor pain. Modern studies have also shown that Sanyinjiao can relieve uterine contraction
      pain by relieving uterine smooth muscle spasm, improving the state of uterine ischemia and
      hypoxia, releasing a variety of central analgesic substances and so on Spleen and blood,
      liver tonifying and kidney tonifying. Therefore, on the basis of conventional PCIA analgesia
      combined with electroacupuncture at Zusanli and Sanyinjiao, we may play an auxiliary role in
      analgesia for puerpera after cesarean section.
