“…When the CTM is visualized, the risk of subcutaneous and esophageal placements decreases. [20,21] Although EC is a difficult procedure to perform unaided, the technique can be easily learned and recalled by minimally trained health care providers. [22] The success rate and velocity of application of EC varies, depending on the training models.…”

“…The accurate and appropriate needle guidance to procedural targets is very crucial during percutaneous interventional procedures. Feng et al displayed a method that a 0.9-mm microimaging fiber was delivered into a 16-gauge needle to develop a visual puncture system for performing needle cricothyroidotomy [13]. However, image resolution was so poor to identify airway structure and we could not identify every tissue layer (skin, fat, muscle, cartilage, cricothyroid membrane, and vessels) when the fiber was advanced into the trachea.…”

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.

“…In our previous experiments, a microimaging fiber (0.8 mm) was integrated into a triple-lumen catheter to perform visual sputum suctioning [11, 12]. In addition, we also inserted a 0.8 mm microimaging fiber into an 18 G needle to guide pericardiocentesis and a 14 G needle to guide visual needle cricothyroidotomy [13, 14]. Because of the advantages provided by the small fiber diameter, we integrated the microimaging fiber into a nasogastric tube to guide nasogastric tube insertion.…”

Background. Conventional nasogastric tube placement is an essential clinical procedure; however, complications may arise from blind manipulation. We tested the feasibility and efficiency of a visual nasogastric tube insertion system (VNGS) using a manikin. Methods. A microimaging fiber (0.8 mm) was integrated into the nasogastric tube to create the VNGS. Twenty inexperienced physicians were enrolled and assigned to the visual or conventional group. Each physician performed 10 repeated nasogastric tube insertions with visual guidance or the conventional method; another 20 inexperienced medical students received nasogastric tube insertion training using visual guidance or the conventional method. Results. The nasogastric tube successfully reached the stomach and the narrow anatomic structures were visualized with the VNGS. Time required for insertion was significantly shorter in the visual group compared to the conventional group (22.56 ± 3.08 versus 37.30 ± 4.12 seconds, P < 0.001). Tube misplacement was observed in 19/100 cases (19%) in the conventional group; no misplacement was observed in the visual group. Less mucosal damage was noted in the visual group (3.43 ± 1.63 versus 9.86 ± 2.31 cm2). Medical students performed better NGT insertions (shorter insertion time and less procedure-related complications) after undergoing the visual guidance training. Conclusions. The VNGS may provide a new technique for nasogastric tube insertion applicable to clinical use or simulation training.
