摘要 目的:探讨正常及过度通气状态下丙泊酚对重症颅脑损伤患者脑组织氧分压及颈静脉血氧饱和度的影响。方法:24例急性闭合性颅脑损伤患者,格拉斯哥(GCS)评分≤8分,随机分为3组,每组8例,A组为对照组,按颅脑损伤病人的处理规程进行脱水、降低颅内压等治疗;B组丙泊酚组,维持通气在正常状态(PaCO235mm Hg左右),除常规治疗外,静脉给予镇静剂量丙泊酚;先从静脉给予0.5mg/kg丙泊酚,然后以每小时1mg/kg静脉泵注,测定给药前(T0)、给药后1h(T1)、给药后1.5h(T2)、给药后2h(T3)脑组织氧分压(PbrO2)、颈静脉血氧饱和度、颅内压(ICP)、平均动脉压(MAP)、脑灌注压(CPP)的变化。C组为过度通气丙泊酚组,依次将改变为32-27mm Hg(T1),27-23mm Hg(T3),其余同B组。结果:丙泊酚组T3时间点,脑组织氧分压较T0明显升高、和对照组比较有显著性差异(P<0.05),T2、T3丙泊酚组SjvO2升高,CERO2较对照组为低(P<0.05)。过度通气组通气前后比较以及与对照组比较没有显著性差异。结论:丙泊酚能够改善重度颅脑损伤患者的脑组织氧分压,保持脑氧代谢和脑血流的良好匹配,对过度通气可能导致的脑缺血危险有一定的保护作用,提高对过度通气的耐受。
