Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Damage to teeth, lips, or tongue
- Damage to the trachea or voicebox resulting in pain, hoarseness, or difficulty breathing after the tube is removed
- Esophageal intubation—when the tube is accidentally inserted into the esophagus and stomach rather than the trachea
- Low blood pressure
- Too little or too much ventilation
- Lung injury/collasped lung
Some factors that may increase the risk of complications include:
- Neck or cervical spine injury
- Pre-existing lung disease, such as emphysema
- Poor condition of teeth
- Recent meal
- Diseases that cause muscle weakness, such as myasthenia gravis
When possible talk to your doctor about these risks before the procedure.
