Bismillahirahmanirahim, as i mentioned in my last post entry , here i will continue about the info regarding management of tracheotomy .
Endotracheal Tube Verses Tracheostomy Tube
A
variety of tracheostomy tubes are available, depending on the patient’s
specific needs. Tracheostomy tubes vary
in size, composition, number of parts, and shape. Trach tubes may be made of metal, PVC
material, or silicone and will differ accordingly in the degree of flexibility
they provide. They are either disposable
or reusable.
Cuffed Tracheostomy Tube
Consists of three parts:
- Outer cannula with an inflatable cuff and pilot tube
- An inner cannula
- An obturator
- Cuff trach tubes are generally used for patients who have swallowing difficulties or who are receiving mechanical ventilation.
- Disposable and reusable trach tubes are both available – and can be custom made if needed.
- The outer cannula has an inflated cuff that keeps the airway open. When inflated, this tube seals the airway and prevents aspiration of oral or gastric secretions. The cuff directs air through but not around the tube. It is commonly used when mechanical ventilation is required, to provide a closed airway system.
- The inner cannula of the cuffed tube has a universal adaptor to use with a ventilator and other respiratory equipment. The inner cannulas can be removed, cleaned, and reinserted, unless it is disposable. The inner cannula fits inside the outer cannula. It has a lock to keep it from being coughed out, and is easy to remove for cleaning.
- The obturator has a rounded tip for smoothly inserting the outer tube and avoiding trauma to the tracheal wall. It is important to keep the obturator near the beside in case of an emergency. It is used to insert the tracheostomy tube.
- The cuffed tube with disposable inner cannula is used to obtain a closed circuit for ventilation; cuff should be inflated when using with ventilator – just enough to allow for minimal airleak; should be deflated when/if a patient uses a speaking valve; cuff pressure needs to be checked twice daily; inner cannula is disposable. The same aforementioned items pertain to a cuffed tube with reusable inner cannula with the exception that the inner cannula is NOT disposable – it can be reused when cleaned properly and thoroughly.
Cuffless tubes
- Rarely used in acute care settings
- More suitable for long term ventilation
- Cuffless tube is usually double-lumen – patient must have effective cough and gag reflex to prevent aspiration risk
- Non-cuffed or (cuffless) trach tubes are used to maintain a patient’s airway when a ventilator is not needed.
- Also used for patients who are ready for decannulation. Patient may be able to eat and may be able to talk without a speaking valve
Fenestrated Tube
- Have an opening on the posterior wall of outer cannula – allows for air flow through the upper airway and trach opening;
- Allows patient to speak and produce a more productive cough
- Often used during weaning process
Used for ventilated patients who are not able to tolerate
the speaking valve; there is a high risk for granuloma formation at the site of
the fenestration (hole). There is a
higher risk for aspiration of secretions; it may be difficult to ventilate the
patient adequately
Communication and Tracheostomies
Some trach tubes are
designed to allow patients to speak
Patients being weaned off trach tubes may have either a
cuffless, fenestrated tube or a trach button that does not extend into the
trachea enough to restrict airflow past the larynx
For long-term Trach patients
Speaking is possible with these options:
A fenestrated inner cannula inside a cuffed outer cannula –
allows for speech when cuff is deflated (some tubes expand on inspiration and
deflate on expiration versus manually deflated cuffs)
A tracheostomy speaking valve is a device that attaches to
the trach tube – it contains a diaphragm that opens on inspiration and closes
on expiration so that air is exhaled through the vocal cords and upper airway –
the cuff must be COMPLETELY deflated during speaking valve to allow for
exhalation through the upper airway
A speaking trach tube forces air or
oxygen from an outside source to flow across the vocal cords, independent of the airflow within a
closed system created by a cuffed trach tube.
The patient has control over this air line with a thumb port.
