Abstract:

Objective: To explore the clinical characteristics and death-related factors of patients with tuberculosis-destroyed lung (TDL) undergoing invasive mechanical ventilation (IMV). Methods: A retrospective study was conducted in 107 TDL-IMV patients admitted to the intensive care unit of Chengdu Public Health Clinical Center from January 2017 to December 2021.The epidemiological data, complications, comorbidities, acute physiology and chronic health status scores (APACHE Ⅱ score), sequential organ failure scores (SOFA score), causes of IMV, laboratory test results, and clinical outcomes, etc., of the patients were collected. The above indicators in patients with different clinical outcomes were compared and analyzed, and unconditional multivariate logistic regression was used to analyze the influencing factors of death in TDL-IMV patients. Results: Of the 107 subjects, 42 (39.3%) died and 65 (60.7%) survived. Univariate analysis showed that 52.4% (22/42) of the patients in the death group were complicated with chronic obstructive pulmonary disease, which was significantly higher than that in the survival group (20.0%, 13/65, χ2=12.154, P=0.000); IMV for acute respiratory failure accounted for 52.4% (22/42), which was significantly higher than that of survival group (23.1%, 15/65, χ2=9.685, P=0.002); the albumin level ((25.34±4.22) g/L) was significantly lower than that in the survival group ((28.71±6.26) g/L, t=3.065, P=0.002); N-terminal pro-B-type natriuretic peptide level (median (quartile): 993.45 (869.32, 1096.61) ng/L) was significantly higher than that of survival group (649.26 (528.40, 789.82) ng/L, U=-7.085, P=0.000). Further multivariate logistic regression analysis showed that comorbidities with chronic obstructive pulmonary disease (OR=4.999, 95%CI: 1.253-19.937), IMV treatment for acute respiratory failure (OR=8.548, 95%CI: 2.045-35.729), hypoproteinemia (OR=13.069, 95%CI: 2.662-64.156) and high levels of N-terminal pro-B-type natriuretic peptide (OR=11.354, 95%CI: 2.809-45.888) were independent risk factors for the death of patients with TDL-IMV. Conclusion: Patients with TDL-IMV have a high risk of death, especially those who complicated with chronic obstructive pulmonary disease, undergoing IMV treatment due to acute respiratory failure, hypoproteinemia and high level of N-terminal pro-B-type natriuretic peptide.
