ADVERSE EFFECTS, DELAYED WOUND HEALING
Perioperative pain management is one of the primary tasks of anesthesiologists. Poor pain control can have a range of adverse effects on patients. During hospitalization, poor perioperative pain control is associated with increased incidence of nausea and vomiting, impaired immune function, increased cardiac and pulmonary stress, delayed wound healing and prolonged hospitalization [The incidence of postoperative pain may be a bit higher than we thought. A recent meta-analysis showed that the incidence of moderate to severe postoperative pain in discharged patients ranged from 31% one day after discharge to 58% one to two weeks after discharge [In recent years, less opioids and multimodal analgesia have been widely concerned and strongly recommended in perioperative pain management [Ultrasound-guided nerve block is one of the widely used perioperative analgesia methods. There are a variety of nerve block techniques to relieve incision pain in patients undergoing different operations, such as abdominal transverse fascia block, quadratus lumborum block and paravertebral nerve block [
