The quadratus lumborum (QL) block facilitates the administration of anaesthesia to the anterior abdominal wall. The use of ultrasound (US) improves the accuracy of the QL block and reduces the risk of adverse events. Electromyography (EMG) in combination with US for muscle plane blocks has not been described previously. We postulated that the addition of EMG-guided needle positioning might assist the execution of this block. This case report describes the first use of combined needle EMG and US to carry out a QL block performed for postoperative analgesia following an open appendicectomy.
