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.
腰方肌(QL)阻滞有助于对前腹壁进行麻醉。超声(US)的使用提高了QL阻滞的准确性并降低了不良事件的风险。肌电图(EMG)与US联合用于肌肉平面阻滞此前尚未见报道。我们推测,增加EMG引导的针定位可能有助于实施该阻滞。本病例报告描述了首次联合使用针电极肌电图和US进行QL阻滞,用于开放性阑尾切除术后的镇痛。
