Light-wand (Trachlight) guided nasotracheal intubation

We report that Trachlight-guided nasotracheal intubation might be achieved successfully and traumatically without removal of a stiff internal stylet. Endotracheal tube was mounted on a Trachlight with the stylet in position and bent to form a less sharp curvature than a right angle, namely 40-60 degree, at 7 cm proximal to the endotracheal tube tip. Forty-six patients scheduled for nasal intubation were studied to measure the intubation time and the success rate with the use of Trachlight. The tracheas were successfully intubated in 89% of patients. We suggest that Trachlight-guided nasotracheal intubation could be clinically feasible without traumatic complication when applied with a stiff stylet in position and this approach is a useful method for nasal intubation.
