Tracheostomy is an opening created in the trachea to allow for an alternative airway. It provides benefits like improved breathing, secretion removal, and ventilation assistance. Tracheostomies are indicated for respiratory obstruction, retained secretions, or respiratory insufficiency. The procedure involves making an incision through the neck and trachea to insert a tube. Post-op care includes tube maintenance and cleaning to prevent complications like infection, stenosis, or fistula formation. Decannulation is the process of removing the tube when the underlying condition has resolved.
2. Tracheostomy is making an opening in the anterior
wall of trachea and converting it into a stoma on the
skin surface.
Functions of tracheostomy-
• Alternate pathway for breathing.
• Improves alveolar ventilation.
• Protects the airways.
• Permits removal of tracheobronchial secretions.
• Intermittent positive pressure respiration.
• To administer anaesthesia.
3. INDICATIONS-
1. Respiratory obstruction-
• Infections -Acute laryngo-tracheo-bronchitis, acute epiglottitis, diptheria, ludwing’s
angina, peritonsillar abscess.
• Trauma – external injury of larynx and trachea, fracture of mandible or maxillofacial
injuries.
• Neoplasms.
• Foreign body larynx.
• Oedema larynx due to steam, irritant fumes or gases , allergy
.
• Bilateral abductor paralysis.
• Congenital anomalies – Laryngeal web,cysts,tracheo-oesophageal fistula,bilateral
choanal atresia
4. 2. Retained secretions
• Inability to cough –
• 1. coma of any cause like head injuries, CVA narcotic abuse.
• 2. Paralysis of respiratory muscles in spinal injuries,polio, GB
syndrome.
• 3.spasm of respiratory muscles, tetanus, eclampsia, strychnine
poisoning.
• Painful cough – chest injuries , multiple rib fractures , pneumonia.
• Aspiration of pharyngeal secretions – bulbar polio ,polyneuritis, bilateral
laryngeal paralysis.
3. Respiratory insufficiency
Chronic lung conditions , emphysema , chronic bronchitis,
bronchiectasis, atelectasis
6. TECHNIQUE
Whenever possible endotracheal intubation should be
done before tracheostomy , especially in infants and
children.
POSITION - Patient lies in supine with a pillow under the
shoulder so that neck is extended. This brings the trachea
forward.
ANAESTHESIA – No anaesthesia is required in
unconcious patients or when in an emergency procedure.
In concious patients, 1-2%lignocaine with epinephrine is
used. Sometimes, general anaesthesia with intubation is
used.
7. STEPS
1. A vertical incision is made in the middle of the neck , extending
from cricoid cartilage to just above the sternal notch.( It gives
rapid access with minimum of bleeding and tissue dissection.)
2.Tissues are dissected in the midline. Dilated veins are either
displaced or ligated.
3. Strap muscles are separated in the midline and retracted laterally.
4. Thyroid isthmus is displaced upwards or divided between the
clamps , and suture ligated.
5. A few drops of 4% lignocaine are injected into trachea to suppress
the cough when trachea is incised.
6. Trachea is fixed with a hook and opened with a vertical incision in
the region of 2nd and 3rd rings . This is then converted into a circular
opening.
8. 7. Tracheostomy tube of appropriate size is inserted and
secured by tapes.
8. Skin incision should not be sutured or packed tightly as
it may lead to development of subcutaneous
emphysema.
9. Gauze dressing is placed between the skin and flange
of the tube around the stoma.

10. POST-OP CARE
• Periodic check of tube patency and position.
• Cuff Management- periodic deflation to prevent pressure
necrosis/stenosis of trachea.
• Care of Tube- change on 3rd day (after the tract has
formed) and subsequently, once in a week (to prevent
granulation tissue formation)
• Wound Dressing (to prevent maceration and skin
erosion)
• Periodic tracheo-bronchial toilet using suction tube with
Y-connector
• Supportive care such as-
prevention of crusting/tracheitis by humidification or instillation of
RL/NS/mucolytic agents
Analgesics and antibiotics
11. COMPLICATIONS
1. Immediate (at the time of operation)
• Aspiration
• Apnea (due to sudden CO2 wash out)
• Bleeding
• Collapse of lungs/Pneumothorax
• Damage to surrounding structures
• Embolism- Air
2. Intermediate (within first few hours/days)
• Hemorrhage
• Displacement or blocking of tube
• Subcutaneous emphysema
• Tracheitis and tracheobronchitis with crusting in trachea
• Lung abscess
• Local wound infection and granulations
• Dysphagia
12. 3. Late (after prolonged use of tube for weeks/months)
• Hemorrhage (due to erosion of major vessels)
• Laryngeal stenosis (due to perichondritis of cricoid cartilage).
• Tracheal stenosis (due to tracheal ulceration and infection).
• Tracheo-oesophageal fistula.
• Problems of decannulations.
• Persistent tracheo-cutaneous fistula.
• Problems of tracheostomy scar.
• Corrosion of tracheostomy tube and aspiration of its fragments into
the tracheo-bronchial tree (FB).
13. DECANNULATION
• Process of weaning the patient off the tracheostomy tube
• Prior to decannulation, rule out proximal airway obstruction by-
1. taking X-ray soft tissue neck- AP & Lateral views or
2. chest X-ray (to rule out obstruction above or below the
tracheostome) or
3. Direct/ Indirect laryngoscopy
4. ABG analysis (in C/O children)
• STEPS:
Tracheostomy tube is corked and patient observed for 48hrs
If tolerated by the patient, tube is removed and wound is
sutured/strapped
In C/O children, additional precautions are taken
