AbstractObjective: To explore the application value of color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps in patients with head and neck burns complicated with upper respiratory tract obstruction. Methods: From July 2013 to June 2018, 17 patients with head and neck burns complicated with upper respiratory tract obstruction, including 15 males and 2 females, aged 19-63 years, were hospitalized in our unit and treated with color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps. Before operation, the trachea was examined by color Doppler ultrasonography to specify condition of trachea and peribronchial tissues and organs for comprehensive assessment, so as to confirm optimal incision site of puncture and pathways as well as specify distance from anterior cervical skin to intima of anterior tracheal wall. Then, under real-time guidance of color Doppler ultrasound, percutaneous dilational tracheostomy with dilatation forceps was performed. The position, shape, inner diameter, and intraluminal abnormalities of trachea of patients before operation, abnormal location of peribronchial vessels and thyroid, distance from anterior cervical skin to intima of anterior tracheal wall, success rate of puncture, surgical time (from skin disinfection to successful catheterization), success rate of catheterization, intraoperative blood loss, heart rate, blood pressure, respiration, percutaneous oxygen saturation, and presence or absence of complications such as vascular/thyroid injury, emphysema, pneumothorax, suffocation, postoperative hemorrhea, wound infection after operation were observed and detected. Results: (1)Preoperative color Doppler ultrasonography showed that the trachea of one patient deviated from the anterior median line of neck 13 mm to the right; 17 patients had edema of different degrees in the cervical soft tissue and more secretions in the trachea; 3 patients had the trachea changed from round to oval with reduced anteroposterior diameter; 1 patient had a small artery obstruction at the conventional puncture point; 2 patients had the trachea covered by the congestive and swollen isthmus of the thyroid between the first and the third tracheal cartilage rings; 16 patients had a distance from anterior cervical skin to anterior tracheal wall intima of 17-33 mm, and 1 patient had a distance from anterior cervical skin to anterior tracheal wall intima of 47 mm. (2) Puncture for 17 patients was successful at one time, and success rate of puncture was 100%. The operation time was 5-11 min, with an average of 7 min, and the success rate of catheterization was 100%. (3) Intraoperative blood loss of patients was less, all not exceeding 8 mL. Intraoperative percutaneous oxygen saturation was maintained between 0.90 and 0.99. The heart rate, blood pressure, and respiration were stable. (4) No complications such as vascular/thyroid injury, emphysema, pneumothorax, suffocation, postoperative massive hemorrhage, or wound infection occurred in any patient. Conclusions: Applying color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps in patients with head and neck burns combined with upper respiratory tract obstruction can not only open up the airway quickly and effectively, but also reduce the complications related to the operation. It is expected to improve the success rate of rescue and improve the prognosis, making it of good application value.
