目的 探讨系统的呼吸功能监测在重型颅脑损伤救治中的意义.方法 对87 例重型颅脑损伤(GCS≤8 分)行系统的呼吸功能监测( 包括血气分析、经皮血氧饱和度、呼气末二氧化碳分压、氧合指数),据此对持续低氧血症48 例行气管切开,28 例随后再行机械通气治疗.将其疗效与无系统呼吸监测的传统治疗组(94 例) 比较.结果 监测组有呼吸功能障碍的56 例中死亡18 例(32－1 ％ ) ,传统治疗组有呼吸功能障碍的69 例死亡32 例(46－4 ％ ),前者病死率明显降低( P＜0－05) .结论 对重型颅脑损伤者系统的呼吸功能监测有利于及早发现呼吸功能障碍,指导和及时调整治疗措施,对于降低此类伤员的病死率有重要意义.“,”Objective To discuss the advantage of systemetic respiratory mornitoring in patient with severe brain trauma. Methods 87 patients with severe brain trauma were systemetically monitored, including blood gas analysis, Sp O 2, PetCO 2 and PO 2/FiO 2. Because of low blood oxygen level, 48 patients with respiratory insufficiency in the monitoring group were treated with tracheotomy. Among them, 28 patients were further treated with machenical ventilation. The curative effect of them were compared with that of 94 patients who were not treated by systemotic respiratory mornitoring (control group). Results In the monitoring group, 56 patients were diagnosed to have respiratory insufficeincy. Among them 18 patients died(32.1%). While in the control group, 32 of 69 patients who were diagnosed to have respiratory insufficeincy died (46.4%). The mortality were significantly lower in the mornitoring group ( P<0.05 ). Conclusions Respiratory monitoring may be helpful in early diagnosis and treament of respiratory failure, and may reduce the mortality of patients with severe brain trauma.
