摘要目的 探讨高流量氧疗与无创机械通气在于术后撤机时合并轻中度低氧血症患者的应用效果。方法 回顾性选取2008—2019年重症监护医疗信息数据库Ⅳ中术后入住ICU 撤机时合并轻中度低氧血症的成人患者732例作为研究对象,通过倾向性评分匹配,按照撤机后治疗方式分为高流量组(213 例)和无创通气组(213 例),比较两组患者基线数据和48 h 再插管率、28 d 再插管率、28 d 病死率、撤机至再插管时间、住院时间及住ICU 时间。再单独分析中度低氧血症患者撤机后两组的上述指标,通过倾向性评分匹配,两组各纳入73 例。结果 轻中度低氧血症患者中,两组的48 h 再插管率、28 d 再插管率、28 d 病死率比较,差异均无统计学意义(P>0.05);高流量组住院时间、住ICU 时间、拔管后再插管时间均长于无创通气组,差异有统计学意义(P<0.05)。中度低氧血症中,两组48 h 再插管率、28 d 再插管率、28 d 病死率、撤机至再插管时间、住院时间及住ICU 时间比较,差异均无统计学意义(P>0.05)。结论 对于术后撤机时合并轻中度低氧血症的患者,高流量氧疗与无创机械通气的主要疗效指标相似,但无创机械通气患者的住院时间和住ICU 时间更短。
Abstract:Objective To investigate the effect of high flow oxygen therapy and non-invasive mechanical ventilation on patients with mild to moderate hypoxemia during postoperative evacuation. Methods A retrospective study of 732 adult patients with mild to moderate hypoxemia during postoperative ICU withdrawal from 2008 to 2019 was included in the Medical Information Mark for Intensive Care Ⅳ. By matching propensity score, they were divided into high-flow group(213 cases) and non-invasive ventilation group (213 cases) according to treatment mode after discontinuation of the machine. Baseline data, 48 h reintubation rate, 28 d reintubation rate, 28 d mortality, time from disengagement to reintubation, length of hospital stay and length of stay in ICU were compared between the two groups. The above indexes of moderate hypoxemia patients in the two groups were separately analyzed after discontinuation of the machine, and 73 cases in each group were included through matching propensity score. Results In patients with mild to moderate hypoxemia, there was no significant difference in the 48 h reintubation rate, 28 d reintubation rate and 28 d mortality between the two groups (P>0.05). The hospitalization time, ICU stay time and intubation time after extubation in the highflow group were longer than those in the non-invasive ventilation group, the differences were statistically significant (P<0.05). In moderate hypoxemia, there were no significant differences in 48 h reintubation rate, 28 d reintubation rate, 28 d mortality, time from discontinuation to reintubation, length of hospital stay and length of ICU stay between the two groups (P>0.05). Conclusion For patients with mild to moderate hypoxemia when weaning from ventilator, the main efficacy indicators of high-flow oxygen therapy were similar to those of non-invasive mechanical ventilation, but hospital stay and ICU stay were shorter in patients with non-invasive mechanical ventilation.
