摘要 目的 评估高流量气管内吸氧(HFETOI)在气管切开患者脱机过程中序贯治疗的可行性及临床疗效。 方法 采用回顾性队列研究方法,选择2015年1月至2019年4月南京医科大学附属苏州医院急诊与重症医学科气管切开接受有创机械通气治疗,需要脱机锻炼的脑卒中患者45例,按脱机过程中给氧方式不同分为高流量气管内吸氧(HFETOI)组22例和气切面罩吸氧(TMOI)组23例。分别于研究开始第0、6、12、24、48 h记录两组患者的心率(HR)、呼吸频率(RR)、平均动脉压(MAP)及痰液黏稠度,并进行床旁动脉血气分析,计算1周内患者需要再次机械通气支持的时间总和,分析HFETOI或TMOI对气管切开患者脱机后氧合的改善作用。 结果 HFETOI组和TMOI组序贯治疗12 h HR(次/min)(82.4±18.4 vs. 90.4±16.7)、24 h HR(79.8±16.8 vs. 88.4±14.6)、48 h HR(78.4±17.1 vs. 87.4±12.4)后差异具有统计学意义(P<0.05);24 h RR(次/min)(17.2±4.1 vs. 22.4±5.4)、48 h RR(15.6±3.9 vs. 21.6±5.2)后两组差异具有统计学意义(P<0.05),两组MAP差异无统计学意义(P> 0.05)。HFETOI组序贯治疗12 h(89.6±15.6 vs. 79.9±16.7)、24 h(93.8±21.5 vs. 80.2±19.6)、48 h(94.2±18.1 vs. 84.6±18.4)后的动脉血氧分压(PaO2, mm Hg)与TMOI组比较差异具有统计学意义(P<0.05)。HFETOI组在序贯治疗48 h后,患者气道内痰液黏稠度与TMOI组比较,差异具有统计学意义(P<0.05)。HFETOI组在序贯治疗一周内需要再次机械通气支持的时间总和(h:12.2±8.3 vs. 21.4±11.5)与TMOI组比较,差异有统计学意义(P<0.05)。 结论 气管切开后患者在试脱机过程中序贯HFETOI,可以维持较高的氧分压,减少缺氧带来的HR和RR的增加,并能够有效稀释痰液,从而减少机械通气支持力度,以达到完全脱机的目的。
