Comparison Between Real-Time Ultrasound-Guided Percutaneous Tracheostomy and Surgical Tracheostomy in Critically Ill Patients
Figure 1
Endotracheal tube repositioning for percutaneous dilatational tracheostomy under ultrasound guidance. (a) Double-linear hyperechogenecity revealed the ET tube. (b) Anechoic filling and the ET tube were identified beneath the tracheal cartilage after saline ballooning. (c) Saline ballooning superior to the cricoid cartilage and pushing of the tracheal cartilage anteriorly by the ET tube tip were identified after pull back. (d) The ET tube tip was identified just superior to the 2nd tracheal ring in another patient. C: cricoid cartilage, ET tube: endotracheal tube, T1 and T2: 1st and 2nd tracheal ring, respectively.
