Abstract: Objective: To explore the application value of nasal tracheal cannula guided by light wand in critical patients in ICU. Methods: The front of metal wire was equipmented with a light-emitting light bulbs,batteries were produced after the termination of a light wand. Endotracheal tube will be set in light stick along slowly, and inserted into the nasal cavity to anterior cricothyroid membrane with ray bright spot for the seeker, then insert the trachea, remove the light stick, inflate airbags. Results: The smooth tubs were in place in 25-60 seconds in 68 cases, all patients were carried out to achieve prominent respiratory purpose of artificial ventilation,had a good tolerance and safety performance, as well as the requirements of a long time inserted tube with no special complications. Conclusions: Light wand guided nasal intubation can be fast, simple and safe to create artificial airway, the success rate is high, it has an important clinical value.
