Objective : Evaluate the decannulation rate of tracheostomy, basic data, relation between duration of prolong intubation and decanulation rate and compare our result with other center in the world.
Study design : Retrospective study
Setting :PhayaoHospital
Methods : 184 patients with tracheostomy data were collected from medical reccod in Phayao hospitat between January, 2007 to December, 2011. General patient data, Indication for tracheostomy, Duration of orotracheal intubation, Decanulation rate and Complication were corrected. All of data were analyzed by SPSS program.
Result : A total of 184 patient were studies. The male to female ratio was 1.42:1. The mean age was 53.8 ±18.75 years. The most common indication for tracheostomy was prolong orotracheal intubation in 54.35% of patients. Decannulation rate was 40.22% of case. The decannulation rate was higher in patients who have orotracheal intubation < 7 days and they were significant decannulate than non-decannulate (p=0.01). The most case of patients who have orotracheal intubation < 7 days were intracranial hemorrhage (included head injury). The complication rate was 20.68%. The common complication was dislodgement of tracheostomy tube. Mortality rate was 1.09%.
Conclusion : In our study, decannulation rate was lower than other studies. This result appropriated with most common indication that was prolong intubation. All most of patient with prolong intubation were multiple medical condition that leading to difficult decanulation or die from their underlying disease. The most common complication can be avoided by intensive postoperative tracheostomy tube care and improved skills tube care of nursing and young doctor.
