Evaluation of the incidence of post intubation tracheal stenosis in patients admitted to intensive care unit of Urmia Imam Khomeini hospital at 2012-2013

Tracheal stenosis is one of the known complications of endotracheal intubation and tracheostomy. In this study we evaluated the incidence of post intubation tracheal stenosis in patients admitted to general intensive care unit (GICU) of urmia emam hospital.

In this follow-up study intubated or tracheostomy's patients admitted to GICU at 2012 – 2013 were evaluated. Patients with GCS= 3, Brain death and those who expired were excluded. SPSS ver.18 soft was used for analysis.

Of 112 intubated or tracheostomy patients with mean age 49.61±21.54 included, 76.8% of them were intubated and 23.25% had tracheostomy,tracheal stenosis in 2 cases (1.8%) of 112 patients was seen, that’s one case after emergency intubation and another case was elective that followed after tracheostomy.With fisher exact test no significant difference between sex, kind of intubation, intubation or tracheostomy and tracheal stenosis was seen (pvalue>0.05). With chi- square test between age groups and under lying diseases and tracheal stenosis there wasn’t any significant difference (pvalue>0.05). On the other hand with T-test significant differences between size of endo tracheal tube or tracheostomy tube and trachteal stenosis were not found. (pvalue>0.05)

Despite appropriate use of tubes and tracheostomy sets and routinely measurement of intra – cuff pressure cuff in intensive care unit, tracheal stenosis was seen.
