C-MAC Videolaryngoscopy Versus Direct Laryngoscopy for Percutaneous Tracheostomy

When preparing an ICU patient for percutaneous dilational tracheostomy, correct positioning of the endotracheal tube is important. During the procedure, it is possible to puncture the cuff. Tracheal tube cuff puncture can lead to failure of ventilation, loss of positive end-expiratory pressure, and possible aspiration of gastric contents blood or secretions. To minimize the risk, in our ICU, we withdraw the endotracheal tube under direct laryngoscopic vision until the cuff is visible at the vocal cords. This maneuver would also facilitate insertion of the Seldinger needle and insertion of the tracheostomy tube below the endotracheal tube. However, this maneuver to remove the endotracheal tube under direct laryngoscopy can sometimes be difficult. ICU patients present frecuently difficult laryngoscopic vision due to airway edema or secretions. In ICU, the videolaryngopy has been shown to be superior to direct laryngoscopy in visualization the upper airway, allowing better laryngoscopic vision.
