As compared with medial approaches for the infraclavicular brachial plexus block, lateral approaches generally have no impact on the phrenic nerve or pulmonary function. A patient experienced transient hemidiaphragmatic paresis after ultrasound-guided lateral sagittal infraclavicular block for lower arm surgery. An accessory phrenic nerve, ie, an anatomical variation, may have been the mechanism of transient hemidiaphragmatic paresis in this patient.
与锁骨下臂丛神经阻滞的内侧入路相比，外侧入路通常不会对膈神经或肺功能产生影响。一位接受超声引导下外侧矢状锁骨下入路用于小臂手术的患者出现短暂性膈肌麻痹。副膈神经，即解剖变异，可能是该患者出现短暂性膈肌麻痹的机制。
