Introduction Ventilator-associated tracheobronchitis is a condition that occurs prior to the development of ventilator-associated pneumonia among patients who have been intubated. This study aimed to determine the impact of nosocomial tracheobronchitis (NTB) related to new bacteria on the outcome in patients with chronic obstructive pulmonary disease (COPD). Methodology A prospective, observational study was conducted in the department of surgical ICU of a tertiary care hospital between May 2019 and December 2019. All patients ventilated, irrespective of age and gender, were enrolled in the study. Individuals who had nosocomial pneumonia, before or followed by NTB, were excluded. Throughout the study, endotracheal aspirates for quantitative bacterial cultures were obtained routinely on admission, weekly thereafter, and whenever NTB or nosocomial pneumonia was suspected. All data were prospectively collected by the researchers from admission day till discharge or death of the patient. The outcomes of NTB patients were compared with those without NTB. Results A total of 24 patients with NTB and 214 patients without NTB were evaluated. There were a total of 24 patients who were diagnosed with NTB and 214 patients were NTB negative. There was a dominance of the male gender in the NTB group; however, the difference was not significant. The most common complication in patients was renal failure. During hospitalization, the tracheobronchitis (ATB) rate was significantly higher in patients with NTB as compared to patients with no NTB, i.e., 18 (75%) vs. 80 (37.4%) (p < 0.001). The mean length of stay in patients with NTB was significantly greater than the NTB negative group (p < 0.0001). The mortality in the case group was significantly greater than in the NTB negative group, i.e., 66.67% vs. 48.50% (p = 0.03). Conclusion NTB is associated with an increased duration of mechanical ventilation and hospitalization in intensive care units. The mortality rate in the NTB group was considerably higher than in the patients who did not have NTB. Future studies can explore the interventional and management aspect of the disease, such as determining whether early administration of broad-spectrum antibiotics can help improve the prognostic outcome of patients with NTB on mechanical ventilation.
引言
呼吸机相关性气管支气管炎是一种在插管患者中发生于呼吸机相关性肺炎之前的病症。本研究旨在确定与新细菌相关的医院获得性气管支气管炎(NTB)对慢性阻塞性肺疾病(COPD)患者预后的影响。
方法
2019年5月至2019年12月在一家三级护理医院的外科重症监护室进行了一项前瞻性观察性研究。纳入所有接受机械通气的患者,不分年龄和性别。排除在NTB之前或之后患有医院获得性肺炎的个体。在整个研究过程中,入院时常规获取气管内吸出物进行定量细菌培养,此后每周一次,以及在怀疑有NTB或医院获得性肺炎时进行培养。研究人员从患者入院日至出院或死亡前瞻性收集所有数据。将NTB患者的预后与无NTB患者的预后进行比较。
结果
共评估了24例NTB患者和214例无NTB患者。共有24例患者被诊断为NTB,214例患者NTB阴性。NTB组男性占主导;然而,差异不显著。患者最常见的并发症是肾衰竭。住院期间,NTB患者的气管支气管炎(ATB)发生率显著高于无NTB患者,即18例(75%)对80例(37.4%)(p<0.001)。NTB患者的平均住院时间显著长于NTB阴性组(p<0.0001)。病例组的死亡率显著高于NTB阴性组,即66.67%对48.50%(p=0.03)。
结论
NTB与重症监护病房机械通气时间延长和住院时间延长有关。NTB组的死亡率显著高于无NTB的患者。未来的研究可以探索该疾病的干预和管理方面,例如确定早期使用广谱抗生素是否有助于改善机械通气的NTB患者的预后。
