After placing an ET tube in the trachea, what should be done immediately?

Once an endotracheal (ET) tube is successfully placed in the trachea, the immediate next step involves ensuring that the airway is properly secured and that effective ventilation can occur. Inflating the distal cuff after removing the stylet is crucial because the cuff serves to seal the airway, which minimizes the risk of air leaks during ventilation and prevents aspiration of secretions. This step is imperative as it confirms the endotracheal tube is effectively isolating the trachea from the esophagus, ensuring that positive pressure ventilation can be delivered without bypassing into the gastrointestinal tract.

Moreover, removing the stylet is necessary to avoid any potential injury to the airway and to ensure the tube is in the proper position. After the cuff is inflated, the tube can then be secured, typically using adhesive tape or another securing device, to prevent accidental dislodgement. Thus, this action lays the groundwork for effective ventilation and patient safety following intubation.
