Adult Critical Care Specialty (ACCS) Practice Exam

In preparation for a difficult intubation with a video assist device, what should a specialist also obtain?

1. A preformed rigid stylet

2. A fiberoptic bronchoscope

3. A retrograde wire kit

4. A gum elastic bougie

The correct answer is: A preformed rigid stylet

Obtaining a preformed rigid stylet is key in preparation for a difficult intubation because it aids in providing a more stable and controlled means of guiding the endotracheal tube into the trachea. The rigid stylet maintains the shape of the tube, which is particularly advantageous in situations where anatomy might be distorted due to either physiological conditions or external factors. This tool allows for optimal positioning and alignment of the endotracheal tube with the trachea, significantly improving the chances of successful intubation in challenging scenarios, such as those presented by limited neck mobility, anatomical anomalies, or anterior laryngeal positioning. When approaching intubation procedures, having a variety of tools available is crucial because conditions can change rapidly. While devices like fiberoptic bronchoscope, retrograde wire kits, and gum elastic bougies have their respective roles in aiding intubation, the primary function of a preformed rigid stylet is to facilitate the passage of the endotracheal tube itself during a difficult intubation, making it an essential tool in this context.
