在选择性切断脊神经后根治疗脑瘫下肢痉挛手术中,单用静吸复合全麻已见报道,但存在电刺激脊神经后根而反射性引起心脏交感神经兴奋,从而引起心率加快,血压升高等缺点［１,２］。本院采用硬膜外阻滞复合气管内全麻,这一具有“两级阻断”效应的麻醉方法［３］,可以克服前述麻醉方 Selectively cut off the dorsal root of the spinal nerve in the treatment of lower extremity spastic surgery of cerebral palsy, single static combined with general anesthesia has been reported, but there is electrical stimulation of the dorsal root of the spinal nerve and reflex cardiac sympathetic activity caused by excitement, causing rapid heart rate, high blood pressure shortcomings [1,2]. Our hospital with epidural block composite tracheal anesthesia, this has a “two-stage block” effect of anesthesia [3], can overcome the anesthesia side
