Evaluation of transmitted glow point at a priori chosen depth (1 cm below vocal cords) for lightwand intubation: a prospective observational study.

Anaesthesiologists should be aware of the appropriate point of the transmitted glow on the patient's neck when performing lightwand intubation. We suggest that this point is approximately 1 cm below the upper border of the cricoid cartilage.Trial registration: ClinicalTrials.gov NCT03480035.
