Endotracheal intubation is when a tube is inserted through the mouth down into the trachea (the large airway from the mouth to the lungs) to administer mechanical ventilation. Before surgery, we often do it under deep sedation. In emergencies, the patient is often unconscious at the time of this procedure.
There are many different types of catheters and lines to access your blood, whether used for taking blood samples, administering medication, or receiving dialysis. You are probably already familiar with a standard IV, or peripheral IV, usually placed in the hand or arm. Still, there are other types of access, such as a central venous catheter (CVC).
In the past one and half years, hospitals worldwide have seen an unprecedented number of patients with respiratory failure due to COVID-19. Current studies suggest that 10-15% of patients hospitalized with COVID-19 require invasive mechanical ventilation, frequently for prolonged periods. A significant proportion of patients required mechanical ventilation for more than 21 days.
During the indwelling of the tracheal intubation, airway secretions will accumulate in the lumen of the tracheal intubation and severely reduce the diameter of the lumen, which will increase the work of breathing and block the patient's airway. To ensure that this does not happen, we need to replace the tracheostomy tube frequently. However, in practice, it is believed that the best time to replace the tracheostomy tube without an inner cannula is every 7 to 14 days.
