摘要
目的 评价早期过度换气疗法在治疗格拉斯哥昏迷评分 (GCS)≤ 5分颅脑损伤的效果。方法 将 72例GCS≤ 5分颅脑损伤病人随机分成过度换气治疗组 (n =36 )和对照组 (n =36 ) ,观察过度换气治疗组治疗前后血气值变化 ,记录两组病例的存活数 ,死亡数 ,存活时间。结果 过度换气能降低动脉血二氧化碳分压 (P <0 .0 1) ,提高动脉血氧分压 (P <0 .0 1)。过度换气治疗组和对照组的病死率在统计学上无显著性差异 (P >0 .0 5 )。结论 早期过度换气能延长GCS≤ 5分病人的生存时间 ,但不能降低其病死率。
Objective To evaluate the effect of early hyperventilation in patients with severe traumatic brain injury(GCS≤5).?Methods Seventy two patients with GCS≤5 were randomly divided into the hyperventilated group(36 cases) and the control group(36 cases).The arterial blood gas was measured before and after treatment in the hyperventilated group. Number of the survival,the dead as well as survival time length of both groups were recorded.?Results Hyperventilation increased pressure of oxygen (P<0.01),and decreased partial pressure of carbon dioxide (P<0.01).There was no significant difference in death rate in both groups(P>0.05).?Conclusion Early moderate hyperventilation is significantly effective on increasing survival rate rather than reducing mortality in patients with GCS≤5.
