作者发现严重痉挛性双瘫患儿围手术期往往出现霍夫曼反射(H-reflex,简称HR)亢进,电诱发的深(肌)腱反射呈许多生理学特性,可用以监测脊髓运动神经的兴奋性。给痉挛性双瘫患儿行选择性背侧脊神经切断术(SDR)时,术中约半数患儿可引出HR。在氟烷或异氟醚麻醉下行SDR,则HR完全消失,但在N_2O-阿片类药物麻醉时,究竟是N_2O还是阿片类药物能抑制HR尚未阐明。脑瘫患儿的脊髓反射增强是由于脊髓以上控制单突触反射弧(monosynaptic reflex are)的作用减弱所致。兴奋输入肌梭的调节减退,则肌张力增高,腱反射亢进N_2O可提高脊髓反射正常人的肌张力,但
The authors found that children with severe spastic diplegia tend to have H-reflex (HR) hyperactivity during perioperative period. Electrical-induced reflexes of the deep tendons have many physiological properties that can be used to monitor the excitability of spinal motor nerves Sex. In spastic diplegia children with selective dorsal spinal nerve transection (SDR), about half of children with surgery can lead to HR. In the halothane or isoflurane anesthesia under SDR, the HR disappeared completely, but in the N_2O-opioid anesthesia, whether it is N_2O or opioid can inhibit HR has not yet been clarified. Spinal reflexes in children with cerebral palsy are due to a weakened effect of the monosynaptic reflex are above the spinal cord. Excitement into the regulation of muscle spindle decreased, then increased muscle tone, tendon hyperreflexia N_2O can enhance the spinal cord normal muscle tone, but
