To better determine the level of pain, there are very many methods in pain scoring, the most commonly used are visual analog assessment and numerical assessment methods, which are easy to use. In anesthesiology, it is more practical for the assessment of postoperative symptoms. After the surgery, the surgeon should score the patient’s pain and based on the pain score then treat the patient accordingly. Pain scores are like numerical scores, with 0 indicating no pain, 1-3 indicating mild, 4-7 indicating moderate, and 7-10 indicating severe pain, i.e., pain that is intolerable. Pain that is more than moderate must be treated with analgesia. The formulation of postoperative analgesia is configured according to the patient’s general condition, surgical procedure, and information about the postoperative pain score, in order to achieve individualized treatment to reduce the occurrence of patient complications. Postoperative analgesia enhances patient comfort, which is an important task in anesthesiology.
