Serratus anterior plane block for upper abdominal incisions

Abstract

Regional anaesthetic techniques for patients undergoing laparotomy have been shown to provide optimal postoperative analgesia and allow early mobilisation, and thus, enhance recovery. The serratus anterior plane block, first documented in 2013, has been suggested as a potential alternative to thoracic paravertebral and central neuraxial blockade for chest wall and upper abdominal incisions as it can provide analgesia from T2 to T9. Although there are published cases of this block being used for chest wall analgesia, there are currently no published cases of this block being used for abdominal incisions. We report our experience with two patients, using ultrasound-guided serratus anterior plane blockade with catheter insertion following laparotomy.
