Clinical Effect of Electroacupuncture on Postoperative Analgesia After Cesarean Sectionanalgesia After Cesarean Section

Overview

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.
