在高位颈髓损伤中,呼吸衰竭是导致死亡常见的原因。它的基本病理生理的改变,在于肋间肌麻痹加上膈神经原的损害,肋间肌麻痹之后,因通气功能不全,发生缺O_2及CO_2潴留。若是损伤在C_2——C_4段或其附近时,呼吸中枢或膈神经元虽然受到影响,以致膈肌运动减弱或消失,形成气体交换障碍,因而导致呼吸衰竭发生死亡。现今对脊髓受到横断损伤之后,虽有很多治疗办法,如低温疗法,高压氧,肾上腺皮质类固醇,抗纤维蛋白溶解、抗儿茶酚以及手术沿中线脊髓切开术等等疗法(有些尚处于实验阶段)但最终效果不良,可以说尚无更好的良策。但对于损伤 In high cervical cord injury, respiratory failure is a common cause of death. Its basic pathophysiological changes, intercostal muscle paralysis plus phrenic nerve damage, intercostal muscle paralysis, due to ventilatory insufficiency, lack of O_2 and CO_2 retention. If the injury is at or near C_2 - C_4, the respiratory center or phrenic neurons are affected, which results in the weakening or disappearance of diaphragmatic movement and the formation of a gas exchange disorder, resulting in the death of respiratory failure. Although many treatments such as hypothermia, hyperbaric oxygen, adrenocortical steroids, anti-fibrinolysis, anti-catechol, and surgery along median-line myelotomy have been performed (although some are still experimental Stage) But the final result is poor, we can say there is no better strategy. But for damage
