BMC Anesthesiol

Background: To compare ultrasound-guided tracheal intubation (UGTI) versus Shikani optical stylet (SOS)-aided tracheal intubation in patients with anticipated normal airway. Methods: Sixty patients aged 18-65 years old who presented for elective surgery under general anesthesia were recruited in this prospective randomized study. They were assigned into two equal groups, either an ultrasoundguided group (Group UG, n = 30) or an SOS-aided group (Group SOS, n = 30). After the induction of anesthesia, the tracheal intubation was performed by a specified skilled anesthesiologist. The number of tracheal intubation attempt and the duration of successful intubation on the first attempt were recorded. Complications relative to tracheal intubation including desaturation, hoarseness and sore throat were also recorded. Results: The first-attempt success rate is 93.3% (28/30) in Group UG and 90% (27/30) in Group SOS (P = 0.640). The second-attempt was all successful for the 2 and 3 patients left in the two groups, and the overall success rate of both groups was 100%. The duration of successful intubation on the first attempt of Group UG was not significantly different from that of Group SOS (34.0 ± 20.8 s vs 35.5 ± 23.2 s, P = 0.784). One patient in Group SOS had desaturation (P = 0.313), and there was none hoarseness in the two groups. Sore throat was detected in both group (4 in Group UG, 5 in Group SOS, P = 0.718). Conclusion: Ultrasound-guided tracheal intubation was as effective as Shikani optical stylet-aided tracheal intubation in adult patients with anticipated normal airway.

“…It has been widely used in clinic because of its fast, effective and little effect on hemodynamics. 2,3 Ultrasound technology is more and more used in clinical anesthesia due to its safe, reliable, repeatable and easy to realize characteristics. In the case of endotracheal intubation, using ultrasound image, we can determine the endotracheal tube size, [5][6][7] observe the position of cricothyroid membrane and glottis, 1,4,5,8 guide tracheal intubation, 1,4,5 judge whether the tracheal tube enters the trachea, 1,4,5,9 and judge whether the position of tracheal tube is correct.…”

“…It not only has the characteristics of a beroptic bronchoscope but also very light and convenient. 2,3 UGTI and SOS-aided tracheal intubation have some similar manipulations in the intubation: opening the mouth with hands, placing the styletted tube, and inserting the tube with the guidance of ultrasound or light spot and optical stylet. And they are particularly effective for some special patients, who has limitation of mouth opening or di cult visualization of the airway obscured by secretions or blood.…”
