目的回顾性分析慢性阻塞性肺疾病(慢阻肺)急性加重合并呼吸衰竭进行有创-无创序贯通气治疗患者的临床资料,探讨治疗失败的原因。
方法选择2013年1月1日至2017年9月30日南京医科大学呼吸ICU(RICU)收治的慢阻肺急性加重合并呼吸衰竭并进行有创-无创序贯通气治疗的患者64例,以7 d内再插管、死亡或自动出院为研究终点,比较成功组(43例)与失败组(21例)患者的入住RICU时的急性生理与慢性健康(APACHE)Ⅱ评分、慢阻肺ABCD分组、胸部CT中肺动脉干/升主动脉直径比值(肺/升比值)、N末端脑钠肽前体(NT-proBNP)、入住RICU及有创机械通气拔管时的PaCO 2、PaO 2、白细胞总数及降钙素原水平,分析两组之间各变量差异,并寻找差异变量的Cut-off值。
结果两组在单变量分析中入住RICU时的APACHE Ⅱ评分(成功组为23±4,失败组为27±6)、肺/升比值(成功组为0.88±0.09,失败组为1.03±0.10)、NT-proBNP、入住RICU时的白细胞总数及降钙素原水平差异均有统计学意义(均 P<0.05)。进一步多变量回归分析中,则只有入住RICU时的APACHE Ⅱ评分( P=0.02)及肺/升比值( P=0.012)差异有统计学意义。所有患者的肺/升比值的ROC曲线下面积为0.894,Cut-off值为0.98。
结论APACHE Ⅱ评分、CT中肺动脉干/升主动脉直径比值是慢阻肺急性加重合并呼吸衰竭患者进行有创-无创序贯通气治疗失败的独立危险因素,肺/升比值>0.98的患者失败率更高。
ObjectiveBy retrospectively analyzing the clinical data of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with respiratory failure, to find the associated factors for failure of invasive-noninvasive sequential ventilation therapy.
MethodsWe conducted a cohort study of 64 patients with AECOPD complicated with respiratory failure, who were treated by invasive-noninvasive sequential ventilation. We took re-intubation, death or spontaneous discharge within 7 days following extubation as the endpoints. By comparing the APACHE Ⅱ score at admission into RICU, the ABCD grouping for COPD, the ratio of the diameter of the pulmonary artery to the diameter of the ascending aorta in chest CT(PA: A ratio), the levels of NT-proBNP, PaCO 2, PaO 2, the total number of leukocytes and the level of procalcitonin, we analyzed the differences between the success group(43 cases) and the failure group(21 cases).
ResultsThe APACHE Ⅱ score at admission to RICU, the PA: A ratio, the level of NT-proBNP, the total leukocytes and the level of procalcitonin at admission to RICU showed significant differences in the univariate analysis( P<0.05). The average APACHE Ⅱ score was 23±4 in the success group and 27±6 in the failure group. The average PA: A ratio was 0.88±0.09 in the success group and 1.03±0.10 in the failure group. In the multivariate regression analysis, there were significant differences only in the APACHE Ⅱ score( P=0.02)and the PA: A ratio( P=0.012). The area under the ROC curve of the PA: A ratio for all patients was 0.894 and the cut-off value of the PA: A ratio was 0.98.
ConclusionThe APACHE Ⅱ score and the PA: A ratio in CT are independent risk factors for failure of sequential ventilation in AECOPD patients complicated with respiratory failure. In particular, patients with a PA: A ratio greater than 0.98 have a higher risk of treatment failure.
