术后疼痛护理的研究进展  Introduction Postoperative pain is one of the most common complaints of patients after surgery. It can be caused by various factors, including tissue damage, inflammation, nerve injury, and psychological stress. Pain can affect the patients recovery, quality of life, and overall satisfaction with their medical care. Therefore, effective postoperative pain management is essential to ensure optimal patient outcomes. The purpose of this article is to review the current research on postoperative pain management and highlight the latest strategies for improving pain control. Types of Postoperative Pain Acute pain is the most common type of postoperative pain. It usually lasts for a few days to a few weeks and is caused by tissue injury and inflammation. Acute pain can be managed with traditional pain medications such as opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and acetaminophen. However, opioid use can lead to unwanted side effects such as respiratory depression, sedation, nausea, and constipation. Therefore, opioid-sparing techniques such as regional anesthesia, multimodal analgesia, and non-pharmacologic interventions are being increasingly used to manage postoperative pain. Chronic pain is less common than acute pain but can occur after major surgeries such as amputations, thoracotomies, and abdominal surgeries. Chronic pain is defined as pain persisting for more than three months after surgery. It can be caused by nerve injuries, scar formation, and psychological factors. Chronic pain can be challenging to manage, and a multidisciplinary approach is often necessary, including pain specialists, physiotherapists, and psychologists. Postoperative Pain Management Strategies Regional Anesthesia Regional anesthesia involves the administration of local anesthetic agents to block specific nerves or nerve plexuses to reduce pain in the immediate postoperative period. Techniques such as epidural analgesia, peripheral nerve blocks, and spin
