Informed Consent for Endotracheal Intubation

Patient and Provider Information

What is Endotracheal Intubation?

Endotracheal intubation is a medical procedure where a plastic breathing tube is placed through the mouth and down into your windpipe (trachea). The tube keeps your airway open and allows oxygen to be delivered directly to your lungs, usually by connecting the tube to a ventilator machine. Intubation is required when a patient: (1) has severe respiratory failure and cannot breathe well enough to stay alive; (2) is undergoing general anesthesia for surgery; (3) has severe head or neck trauma and cannot protect their own airway; or (4) is unconscious or in a coma and at risk of choking.

How is the Procedure Performed?

Intubation is performed by trained emergency, anesthesia, or critical care providers. The clinician will: (1) Give you 100% oxygen through a mask before starting. (2) Inject rapid-acting sedative and muscle-relaxing (paralyzing) medications through your IV to make you sleep and stop your throat muscles from gagging. (3) Use a metal tool with a light (laryngoscope or video screen) to lift your tongue and look at your vocal cords. (4) Slide the soft breathing tube between your vocal cords and into your windpipe. (5) Inflate a tiny balloon cuff on the tube to seal it in place and prevent stomach fluids from leaking into your lungs. (6) Confirm the tube is in the correct place by listening to your lungs, checking a carbon dioxide detector, or ordering a chest X-ray. The process takes less than 5 minutes once the medications are given.

Expected Benefits

Restores immediate flow of oxygen to the brain and vital organs during life-threatening respiratory failure.
Completely protects the lungs from aspiration (stomach acid, vomit, or blood entering the lungs).
Ensures a safe, deep sleep state during major surgical procedures.

Risks and Potential Complications

Sore Throat and Hoarseness: Very common after the tube is removed. This is caused by irritation of the throat and vocal cords, and usually improves in a few days.
Damage to Mouth and Teeth: The metal tool used to guide the tube can scrape the lips, tongue, or throat, or chip teeth. This risk is higher if you have loose teeth or difficult neck mobility.
Incorrect Tube Placement (Esophageal Intubation): The tube can accidentally slide into the food pipe (esophagus) instead of the windpipe. Clinicians verify placement immediately. If missed, it can cause severe lack of oxygen.
Aspiration of Stomach Contents: Stomach fluids can leak into the lungs during insertion, leading to chemical pneumonia or severe lung inflammation.
Low Oxygen and Blood Pressure: During the brief time it takes to place the tube, your oxygen level may drop. The medications used to sedate you can also cause your blood pressure to drop, requiring support drugs.
Cardiac Arrest: In extremely critical, unstable patients, the stress of intubation can cause severe cardiovascular collapse, leading to heart failure or cardiac arrest.

Alternatives to Intubation

Non-Invasive Ventilation (BiPAP/CPAP): Using a tight-fitting face mask connected to a machine that pushes air into your lungs. This is only possible if you are awake, cooperative, not vomiting, and still able to breathe partially.
High-Flow Oxygen Therapy: Using special nose prongs that deliver high volumes of oxygen, but this does not protect your airway if you lose consciousness.
Refusal of Treatment: If you have severe respiratory failure, choosing not to be intubated will lead to a rapid drop in oxygen, loss of consciousness, multi-organ failure, and death.

Patient Acknowledgment and Authorization

I confirm that the clinician has explained why endotracheal intubation is necessary, how it is performed, the benefits, and the risks (especially sore throat, dental damage, or aspiration). I understand the alternatives and the severe risks of refusing treatment. I have had the opportunity to ask questions, and all my questions have been answered. I voluntarily authorize the clinician to perform this procedure.
