Digital Intubation without Stylet: Myth or Reality? Case Report

Open Journal of Anesthesiology 2021年第5期11卷 156-163页

Digital intubation was discovered as one of the first methods to face a difficult airway without direct laryngoscopy. From the very beginning, this technique has been surrounded by much controversy, mainly because it required to be performed by an expert. Nowadays, it remains a useful technique when treating patients with difficult airways, so it is of utmost importance all personnel involved with airway management must know and perfect this technique when scenarios where conventional laryngoscopy or rescue devices for difficult airway are not available or contraindicated. The present work’s main objective is to suggest digital intubation as a safe and effective technique for the management of patients with difficult airways when there are no other devices available. The authors present a successful case of digital intubation on a patient with a difficult airway, demonstrating this technique is useful when performed by expert practitioners and when there is no other equipment available.
