There are three kinds of clinical analgesic methods: oral analgesic, intramuscular or intravenous analgesia, and patient-controlled analgesia (PCA). Among them, oral administration has long-term and short-term effects. Intramuscular or intravenous analgesia also has short-term and long-term analgesic effects up to seven days. And there are two types of self-controlled analgesia: intravenous injection and epidural injection.
At present, postoperative pain relief methods and drugs are quite diverse, each of which has different applicable situations and side effects. It still requires the advice of a professional physician before use. Consider that each patient's physique, physical condition, and surgical methods are different. Therefore, the professionally trained attending physicians in the postoperative pain relief team of various hospitals should provide the best professional choice for the specific postoperative condition based on the evaluation results!
