Comparison of the analgesic effects of dezocine, tramadol and butorphanol after cesarean section

Abstract

At present, the drugs used in the field of postoperative analgesia are mainly opioids. The three analgesics selected in this study are opioid receptor agonists, but opioids are easy to produce adverse reactions. In this study, the visual analogue score of resting pain and dynamic pain at two time points of 4 hours and 12 hours was observed in group B and group C were higher than that in group A (P<0.05), indicating that the analgesic effect of dezocine was better. Follow up observation of adverse reactions, dezocine group patients had fewer adverse reactions (P<0.05). It can be seen that although there are certain differences in the mechanism of these three drugs, there are some relevant evidence that all three drugs can be used safely and effectively for postoperative obstetric analgesia.
