气管切开术后气管狭窄的影响因素分析

Analysis of Influencing Factors of Tracheal Stenosis after Tracheotomy

目的探讨气管切开术后气管狭窄的影响因素。方法选取2010年10月至2016年10月在我院行气管切开术的患者180例作为研究对象,将并发气管狭窄患者作为病例组,未并发气管狭窄患者作为对照组,采用单因素和多因素Logistic回归分析其影响因素。结果 180例气管切开术患者中22例并发气管狭窄,发生率为12.2%;病例组在年龄、术前气管插管时间、术后机械通气时间、呼吸道感染、气囊压迫、切口位置是否过高上与对照组比较差异显著(P<0.05);多因素Logistic回归分析发现年龄≥60岁、切口位置过高、术前气管插管时间≥7 d、术后机械通气时间≥7 d、呼吸道感染是气管切开术后气管狭窄的独立危险因素(P<0.05)。结论气管切开术后气管狭窄的影响因素是多方面的,需要密切关注高危患者。

Objective To investigate the influencing factors of tracheal stenosis after tracheotomy. Methods A total of 180 patients who underwent cut incision in our hospital from October 2010 to October 2016 were selected as subjects, patients with concurrent tracheal stenosis as the case group, patients with no tracheal stenosis as the control group, by univariate and multivariate Logistic regression analysis of the influencing factors. Results 180 cases of tracheotomy patients in 22 cases with tracheal stenosis, the incidence rate was 12.2%; Compared with the control group, there were significant differences in age, preoperative tracheal intubation time, postoperative mechanical ventilation time, respiratory tract infection, balloon compression and incision position in the case group(P<0.05); Logistic regression analysis that age more than 60 years old, high incision position, preoperative tracheotomy intubation time was 7 d, postoperative mechanical ventilation time was 7 d, respiratory tract infection is the independent risk factors of tracheal stenosis after tracheotomy(P<0.05). Conclusion Tracheal stenosis after tracheal stenosis factors are multifaceted, it need to pay close attention to high-risk patients.
