星状神经节阻滞(SGB)是疼痛治疗较常用的阻滞技术,SGB可双相调节血管,或增加头部及上肢血流。SGB的方法各异,共同点是针尖部接近C_7。前入法用一指触知C_6横突前结节,与水平面呈45°角向下进针相当于C_7横突基底部。SGB对头颈上肢胸部一些疾病和疼痛治疗,能取得较好效果。但误入椎管,刺破胸膜发生气胸或血胸等并发症较易发生。鉴于在颈交感干上任何部位阻滞都可出现霍纳
Stellate ganglion block (SGB) is a more commonly used block in the treatment of pain. SGB modulates blood vessels biphasically, or increases blood flow to the head and upper extremities. SGB different ways, the common point is the needle tip close to C_7. Before entering the law with a finger to know C_6 transverse process before the nodules, 45 ° angle with the horizontal down needle is equivalent to C_7 transverse process base. SGB head and neck upper chest some diseases and pain treatment, can achieve better results. However, into the spinal canal, puncture pleural pneumothorax or hemothorax and other complications occur more easily. Horner can appear because of any block in the cervical sympathetic
