The use of airway stents for the treatment of benign airway stenosis is increasingly advocated. However, the long-term safety and efficiency of these devices has not been established. We present a case of tracheal stenosis. which persisted despite open surgical and laser correction. The patient required tracheal stent insertion and is currently well with no respiratory difficulty. The use of metallic or silicon intraluminal stent remains appropriate in cases in which there is defined and relative short-term end point of treatment.
All percutaneous tracheostomies performed in the general intensive care unit (ICU), Hospital Sultanah Aminah, Johor Bahru, Malaysia, from July 1999 to June 2002 were studied. The tracheostomies were performed as an elective bedside technique in the ICU. A total of 352 percutaneous tracheostomies were performed. Eighty-eight percent of the tracheostomies were completed within 15 minutes. The most common complication was bleeding which occurred in 52 patients (14.7%). The rest of the complications encountered were:- transient hypoxia twelve (3.4%), inability/ difficulty to insert tracheostomy tube eight (2.3%), false passage four (1.1%), transient hypotension two (0.6%), pneumothorax two (0.6%), peristomal infection two (0.6%), subcutaneous emphysema one (0.3%), cuff rupture one (0.3%), oesophageal cannulation one (0.3%), and granuloma formation one (0.3%). Conversion to conventional tracheostomies were performed on 7 patients (2%). There was one unfortunate death related to percutaneous tracheostomy. In conclusion, percutaneous dilational tracheostomy can be used safely to manage the airway of critically ill patients.
Cervical rib is a congenital phenomenon that usually occurs in association with upper-limb neurovascular symptoms. The presence of a cervical rib displaces the great vessels that cross the thoracic outlet superiorly and proceed into the neck. We report an unusual case of iatrogenic hemorrhage during a tracheostomy in a patient whose right subclavian artery had been displaced by a cervical rib. Our aim is to alert surgeons to the hidden risks of this phenomenon.
A method of treating tracheostomal stenosis post-laryngectomy is described. The carbon dioxide (CO2) laser is used to fashion and ablate two triangular areas lateral to the stenosed stoma to provide an immediate enlarged stoma for comfortable breathing. This simple procedure is done under local anaesthesia, is almost bloodless, safe and takes just 10 minutes. Over the last five years eight patients underwent this procedure and seven had a satisfactory stoma without the need to use a tracheostomy tube.
During a 6-month period from October 2000 to March 2001, we analysed the indications, methods, waiting period and complications following a tracheostomy at the General Intensive Care Unit (GIGU) of Hospital Kuala Lumpur. There were 49 tracheostomies performed during this period. Thirty of them were performed in the GICU using the percutaneous dilatational method while 19 were performed electively in the Operating Theatre (OT) by the ear, nose and throat (ENT) surgeons. The main indications for a tracheostomy were prolonged mechanical ventilation and airway protection for patients with a poor Glasgow Coma Scale. The average waiting time for a tracheostomy after a decision was made to perform one was 1.34 +/- 0.72 days for a percutaneous tracheostomy and 3.72 +/- 2.52 days for a surgical tracheostomy. This difference was statistically significant (p < 0.001). There was excessive bleeding in 3 patients in the percutaneous tracheostomy group and 1 patient in the surgical tracheostomy group. Percutaneous tracheostomy is now the main method of tracheostomy at the GICU in Hospital Kuala Lumpur. Haemorrhage is the most significant complication of this procedure. However the overall complication rate is comparable with that of a surgical tracheostomy.
PURPOSE: The aim of this study was to evaluate the narrowing of the trachea in head and neck surgical patients who had undergone elective tracheostomy.
MATERIALS AND METHODS: This is a prospective study. Twenty-five patients were included in this study. All these patients had a preoperative elective tracheotomy, preceding major head and neck surgery for head and neck malignancies. An x-ray of the lateral soft tissue neck was taken after a minimum of 6 weeks after the dissimulation of tracheotomy tube. Diameter of the trachea above the stoma (around 2 cm below the cricoid ring that can be clearly seen in lateral x-ray corresponding to the second tracheal ring) was taken as controls. Data were entered into a computer database and statistically analyzed using SPSS for Windows (version 12.0; SPSS, Chicago, Ill). In addition to descriptive statistics for all patients, inferential statistics were used to compare the 2 tracheal diameters across all patients and within the subgroups of men and women. Associations between outcome and other variables were evaluated statistically using an chi 2 test for the categorical data. Other parametric and nonparametric statistical tests were used when appropriate. Criterion for statistical significance was set at P < .05 (Student t test and 2-tailed test).
RESULTS: From this study, 92% (23/25) patients developed narrowing of trachea, all less than 50%. Very early decanulation of tracheotomy shows low or no narrowing at all. There is gradual narrowing in patients in whom dissimulations were performed after 14 days. Ethnicities of Indian decent (13/25) predominate in this study population. Male patients in this study have shorter decanulation period compared with female.
CONCLUSIONS: Elective surgical tracheotomy is a relatively safe procedure resulting in minimum asymptomatic tracheal stenosis.
