  • TRACHEOSTOMY CARE FOR OLD AGED PEOPLE

    Tracheostomy means creating an artificial opening in the windpipe ( trachea ) by a surgical procedure. It is done to facilitate breathing in patients where normal breathing is not possible or in patients who have to be weaned off from the ventilator. Air goes in and out through this opening and whatever secretions the lungs produce can be removed from this opening.



    INDICATIONS

    There are many indications, few of them are

    Congenital conditions affecting wind pipe and larynx.

    2. Tumours affecting the wind pipe.

    3. Injury affecting respiration.

    4. Fractures affecting head and neck

    5. As a precaution in major head and neck surgeries.

    6. In certain patients requiring long term convalescence.



    CARE OF TRACHEOSTOMY



    Care of tracheostomy differs in patients who can do self care or in bed ridden patients who have to be helped with tracheostomy care.



    The basic principle is to keep the air moist as the natural organs that is the mouth and the nose which moisten the air before it enters the wind pipe are bypassed because of tracheostomy. Few tips to keep the air moist are

    1. Drinking lots of water if not contraindicated medically.

    2. Saline wash as advised by doctor.

    3. Humidifying the air in the room by humidifiers.

    4. Care of skin around the tracheostomy

    a. Special care of skin around the tracheostomy should be done in such a way that the water and soap does not enter the tracheostomy. It is best to clean it with sterile piece of gauze. Any secretion or mucus which gathers near the skin should be dislodged gently without disturbing the tracheostomy. Any redness or soreness on the skin should be noted and reported.

    b. If mucoid secretions tend to collect around the tracheostomy then plain gauze can be kept around the opening.

    5. Suction :- it is required time to time to bring out secretions from the lungs. In a patient who is able to take care of the tracheostomy himself it is easy for him to bring it out and the patient will know when to do suction if the chest feels heavy. In bed ridden patients the attendant has to be taught to do gentle suction as and when the secretions can be heard in the chest or when they are coming out.

    6. Few tips for doing suction

    a. Keep the machine off while inserting the suction tube.

    b. Don’t insert the catheter inside for more than 10 seconds specially in patients requiring oxygen.

    c. After insertion of the tube pull out tube a little before switching on the machine.

    d. Rinse the catheter with water or saline in between suctions.

    e. Keep the head up.

    f. Wipe out whatever secretions accumulate around the tracheostomy or in the mouth.

    These are few tips regarding tracheostomy care but ALWAYS CONSULT your Doctor or a senior nursing attendant before doing tracheostomy care by yourself.

    25. 25. Indications & Complications of Tracheostomy
    26. 26. What is “Tracheostomy” The word “tracheostomy” is derived from the Latin “trachea” and “tomein” (to make an opening). Tracheostomy is an operative procedure that creates a surgical airway in the cervical trachea .
    27. 27. What is this & what are its indications ??? Answer at the end of presentation
    28. 28. 1932 to prevent pulmonary infection in neurologically impair patients secondary to infections (poliomyelitis). 1943 to remove bronchial secretions in cases of myasthenia gravis and tetanus. 1951 to reduce the volume of dead space, use in COPD and severe penumonia.
    29. 29. 1950 positive pressure through tracheostomy for patients with poliomyelitis. 1955 obstruction secondary to infection: diphteria, Ludwig’s angina. 1961 Obstructions secondary to tumour, infectious disease and trauma.
    30. 30. Tracheotomy Indications To bypass obstruction
    31. 31. Tracheotomy Indications Prolonged intubation - Need for prolonged respiratory support, such as in Bronchopulmonary Dysplasia - To reduce anatomic dead space and increase the chance for mechanical ventilation withdrawal - To improve the patient`s quality of life (easier toilet, ability to speak and eat, increase the mobility) - Neuromuscular diseases paralyzing or weakening chest muscles and diaphragm
    32. 32.  PROTECTION of AIRWAY  Neurological Diseases(Polyneuritis, GBS)  Coma (GCS<8, risk of aspiration)  Elective Tracheostomy as Adjunct to H&N surgeries  <14 days on ETT(relative)  >21 days on ETT
    33. 33. Tracheotomy Indications Miscellaneous -Congenital abnormalities. (Pierre Robin, Triecher Collins syndromes) - Obstructive Sleep Apnea Syndrome. - Aspirations related to muscle or sensory problems. -Prophylaxis (as preparation for extensive H&N procedures, before radiotherapy for H&N CA) -Cervical spinal cord injuries with respiratory muscles paralysis.

    56. 56.  Tube changes:  Indications: soiled, cuff rupture.  Complications: insertion into a false passage bleeding, and patient discomfort.  Avoid within 1st week.  First tube change by surgeon.  Difficult cases (obese, short and thick neck), be prepared for endotracheal intubation.
    57. 57.  Tracheostomy tube cuff pressures ---20 to 25 mm Hg.  Overly low cuff pressures < 18 mm Hg, may cause the cuff to develop longitudinal folds, promote microaspiration of secretions collected above the cuff, and increase the risk for nosocomial pneumonia.  Excessively high cuff pressures above 25 to 35 mm Hg exceed capillary perfusion pressure and can result in compression of mucosal capillaries, which promotes mucosal ischemia and tracheal stenosis.  Cuff pressure should be measured with calibrated devices and recorded at least once every nursing shift and after every manipulation of the tracheostomy tube.
    58. 58.  Humidification of the inspired gas is a standard of care for tracheostomized patients. Thermovent
    59. 59. Indications For Suctioning • Secretions in the trach • Suspected aspiration of gastric or upper airway secretions • Increase in peak airway pressures when on ventilator • Increase in respirations or sustained cough or both • Gradual or sudden decrease in ABG • Sudden onset of respiratory distress when airway patency is questioned
