ObjectiveTo explore the risk factors for tracheal stenosis caused by tracheotomy or intubation.MethodsFrom July 2010 to July 2020, a total of 44 patients were suffered with tracheal stenosis caused by tracheotomy or intubation at the First Affiliated Hospital of Hunan Normal University as case group (n=44), and 34 patients were suffered tracheotomy or intubation without tracheal stenosis as control group (n=34). The clinical application of intratracheal tube cuff diameter was investigated by univariate comparison, ROC analysis and multivariate logistic regression analysis.ResultsUnivariate analysis showed intratracheal tube cuff diameter (C)/transverse diameter at the level of the clavicle >150%, intubation time>7d, tracheal intubations/tracheostomy ≥2, recurrent respiratory tract infections and replacement of tracheal tube≥ 2 were the influence factors of posttracheostomy tracheal stenosis (PTTS) and postintubation tracheal stenosis (PITS) (P<0.005). Multivariate Logistic regression analysis showed C/T>150% (OR=6.681, 95%CI: 1.164 - 38.363), intubation time>7d (OR=4.723, 95%CI: 1.413 - 15.779), tracheal intubations/tracheostomy ≥2 (OR=4.526, 95%CI: 1.133 - 18.083) and recurrent respiratory tract infections (OR=3.681, 95%CI: 1.177 - 11.513) were positively correlated with PTTS and PITS. The area under the ROC curve (AUC) of C/T>150% was 0.665 with the sensitivity of 0.364 and the specificity of 0.033 (95%CI: 0.555 - 0.775). AUC of intubation time>7 d was 0.717 with the sensitivity of 0.568 and the specificity of 0.133 (95%CI: 0.613 - 0.821). AUC of tracheal intubations/tracheostomy ≥2 was 0.683 with the sensitivity of 0.432 and the specificity of 0.067 (95%CI: 0.574 - 0.791). AUC of recurrent respiratory tract infections was 0.707 with the sensitivity of 0.614 and the specificity of 0.200 (95%CI: 0.603 - 0.811). However, there was no statistically significant difference C/T>150% and those clinical data in Z test (Z=0.839, P=0.402; Z=0.302, P=0.763; Z=0.751, P=0.453).ConclusionIntubation time>7 d, tracheal intubations/tracheostomy ≥2, recurrent respiratory tract infections, replacement of tracheal tube≥ 2 and C/T>150% are risk factors for PTTS and PITS.

Objective To study the clinical feasibility of invasive mechanical ventilation with bilevel positive airway pressure（BiPAP） non-invasive ventilator in the stable patients needing prolonged mechanical ventilation.Methods Eleven patients with respiratory failure admitted in intensive care unit（ICU）of our department，who needed prolonged mechanical ventilation，between Jun 2004 and Nov 2007 were enrolled in the study and followed until death or Jan 2008.The arterial blood gas analysis data，length of stay(LOS)，LOS after changing to BiPAP non-invasive ventilator（Synchrony，Harmony，RESPIRONICS，VPAP III ST-A，RESMED），survival time after discharge(or fulfilled the discharge standards) were reviewed retrospectively.Results The settings of inspiratory pressure，expiratory pressure and respiratory rate of non-invasive ventilation were 21.3 (16-26) cm H2O，4 cm H2O，and 16 min-1，respectively.The LOS (or up to the discharge standard) was (91.5±50.2) days.The LOS (or up to the discharge standard) after changing to BiPAP ventilator was (23.5±12.2) days.The mean survival time after discharge (or up to the discharge standard) was (353.1±296.5) days.Four patients were still alive up to the end of the study.The arterial pH，PaCO2，PaO2，and SaO2 were not significant different before and after changing to BiPAP ventilator.Conclusion The mechanical ventilation with BiPAP non-invasive ventilator via tracheotomy tube is an alternative choice for stable patients needing prolonged mechanical ventilation.

Methods A total of 48 patients from July 2002 to August 2006 were analyzed. According to the correlation among the paralyze degree,smoking, and age with the respiratory obstacle occurrence, we reduce the occurrence of respiratory obstacle in patients with spinal cord injury after the operation via obtaining the effective breath, neck retaining, etc. Results The respiratory obstacle was found in 22 cases; death in 9, in whom 7 died of respiratory failure, 1 of cardiac arrest, and 1 of brain stem hurt. Conclusions The whole palsy, higher level of the spinal cord injury, smoking, and advanced age are the high risk factors of respiratory obstacle after acute cervical SCI. The tracheostomy tube and the adjuvant respiration with the respirator should be accept aggressively for those high risk patients.
