A narrative review of ultrasound-guided serratus anterior plane block

: Ultrasound-guided serratus anterior plane block (SAPB) is located using ultrasound at the level of midaxillary line and fifth rib, a certain amount local anesthetics injected either superficially or deeply into muscle, blocking third to sixth intercostal nerves, long thoracic thoracodorsal nerves. It mainly used in breast surgeries, rib fractures thoracotomy manage pain anterolateral chest wall. The surgery wall often accompanied by severe postoperative pain, leading infection, atelectasis other complications, prolonged hospitalization. However, effective management can reduce occurrence pulmonary promote patients get out bed as soon possible, accelerate recovery patients. Recently, with development ultrasonic technology equipment, SAPB has entered era visualization, further improving safety success rate operations. SAPB, new regional block, higher positioning accuracy, rate, lesser simpler more analgesia effect. Compared epidural paravertebral good anatomical basis; thus, broad application prospect clinics. In this paper, clinical was reviewed.
