“…Although the bronchofiberscope was developed to assist with needle tip location during needle cricothyroidotomy [5], in some cases, such as severe upper airway obstruction, the bronchofiberscope is unable to advance into the tracheal lumen, making it difficult to confirm needle location. In addition, this procedure can also cause secondary discomfort to patients and may induce additional procedure-related complications.…”

“…Management of the difficult airway is usually a challenge, and it is a very important issue for physicians [1]. In some emergency situations, inserting an intravenous needle catheter through the cricothyroid membrane is a lifesaving strategy that temporarily provides ventilation in the "cannot intubate, cannot ventilate" scenario [2][3][4][5]. It can provide the patient oxygen for only a temporary period, until a definitive airway is established.…”

The traditional needle cricothyroidotomy procedure is performed blindly without any medical equipment. Complications including posterior tracheal wall perforation, accidental vessel puncture, and missed tracheal puncture are reported. Therefore, we proposed a dual-wavelength fiber-optic technique based on the technique of near-infrared spectroscopy to assist operators performing needle cricothyroidotomy in a swine model. We embedded optical fibers in a 16-gauge intravenous needle catheter. Real-time data were displayed on an oscilloscope, and we used the program to analyze the data immediately. The change of optical density corresponding to 690-nm and 850-nm wavelengths and hemoglobin parameters (HbO 2 and Hb concentrations) was analyzed immediately using the program in the laptop. Unique and significant optical differences were presented in this experiment. We could easily identify every different tissue by the change of optical density corresponding to 690-nm and 850-nm wavelengths and hemoglobin parameters (HbO 2 and Hb concentrations). Statistical method (Kruskal-Wallis H test) was used to compare differences in tissues at each time-point, respectively. The p values in every tissue in optical density change corresponding to 690 nm and 850 nm were all < 0.001. Furthermore, the p values in every tissue in Hb and HbO 2 were also all < 0.001. The results were statistically significant. This is the first and novel study to introduce a dual-wavelength embedded fibers into a standard cricothyroidotomy needle. This proposed system might be helpful to provide us real-time information of the advanced needle tip to decrease possible complications.
