Effectiveness of Pain Control and Adverse Reactions After Intravenous PCA in Chinese Population

Here, we retrospectively analyzed the proportion of intravenous patient controlled analgesia (PCA) used in a large tertiary hospital in central China, and then further analyzed the proportion of patients with postoperative pain after standardized pain treatment and the incidence of adverse effects. It aims to answer are: 1. The incidence of poor postoperative analgesia and adverse effects of patients with different types of surgery after standardized postoperative pain management of TJ-APS team; 2. It would provide reference for improving the quality of postoperative acute pain management. In addition, it supplements the Chinese data on the incidence of poor postoperative analgesia and adverse effects of patients under the APS standardized postoperative analgesia process.
