RESUMO
The aim of this study was to explore the application value of technical improvements of difficult tracheotomy. Percutaneous dilatational tracheotomy kit combined with traditional surgical tracheotomy was performed on seven patients with various types of difficult tracheotomy surgery from Jan. 2011 to Mar. 2013 in our hospital. The indicators, such as difficulty degree and intraoperative peripheral oxygen saturation changes of each patient, were assessed and analyzed. The average operating time was 20 min (from the beginning of skin incision to the implantation of the tracheal tube), and the time from cutting out tracheal cartilage rings to completely implanting tracheal tube was with 2 min; the intraoperative oxygen saturation degrees were all above 92 %. There were no serious complications, such as intraoperative hemorrhea, asphyxia, cardiac arrest, or others, and no complications, such as postoperative bleeding, pneumothorax, cervical spinal cord injury, tracheal stenosis, tracheoesophageal fistula, or others, appeared. The technical improvements used in difficult tracheotomy could reduce the risk of surgery, difficulties of the surgical operation and postoperative complications and make the operation much more easy and more suitable for the clinical application.
