TRACHEOSTOMY It is an operation in which the windpipe is opened from the front of neck or Surgical creation of an opening into the trachea Indications for tracheostomy 1. Upper airway obstruction: to relieve upper airway obstruction  Infection : laryngeal infection  Neoplasm: carcinoma of larynx and pharynx  Trauma: laryngo-tracheal injuries  Foreign body in larynx  Neurological : B/L vocal cord palsy 2. Respiratory insufficiency : who needs prolong ventilation  Comatose patient without cough reflex: head and chest injuries, poisoning  Neurological condition: myasthenia garvis, poliomyelitis  COPD  Pneumonia 3. Tracheobronchial toileting  Accumulation of secretion in lower respiratory tract prevent proper gas diffusion at alveoli  Tracheostomy allows frequent and adequate pulmonary aspiration  Pulmonary edema  Congestive heart failure  Chronic lung disease and infections Types of Tracheostomy  Depending upon the urgency  Emergency  acute laryngeal obstruction demanding urgent relief.  Elective  Temporary  Permanent Technique  Position / Anaesthesia Tracheostomy Tubes  Metal tubes  Non-metal tubes Types of Tracheostomy Tubes  Portex tube (with cuff)  prevent aspiration  can be used in ventilator  May get blocked- has to be removed  Metal tubes  2 tubes - inner and outer tubes  Advantage - can be used for long period and has and less chance of blockade (if inner tube is blocked, it can be removed and patient breathes through the outer tube) Metallic tube Non metallic tube It has set of outer tube, inner tube and introducer Outer tube is fastened to neck with ribbon strap Inner tube is slipped into outer tube and fused to it by locking device Made of silastic Consists of single tube Advantage Main advantage of metal tube is that , if crusts or mucous plug blocks the inner tube and patient has difficulty in breathing, inner tube can be removed while outer tube remains in trachea and maintains patency of airway allowing the patient to breathe Advantage : Have inflatable cuff and can be connected to ventilator Disadvantage Do not have cuff and cannot produce an airtight seal needed for ventilator If lower end of metal tube do not fit properly, it can cause injury and even erosion of tracheal wall Disadvantage Inflatable cuff itself can cause excess cuff pressure leading to subglottic stenosis if used more than 2-3 weeks Has single tube, so that tube can get blocked due to mucous plug or crust leading to respiratory obstruction Nursing Care of Tracheostomy  Meticulous postoperative care of tracheostomy is necessary to avoid complication  Bed should be close to nursing station  Bedside items - suction machine with sterile suction catheters, 1 extra tracheostomy tube, paper and pen for the patient to communicate  Suction: regular tracheal suction after putting 1-2 ml of sterile saline into trachea to prevent crusting  Humidification : regular humidification( done by inhalation of steam or alternately by electric humidification unit ; nebulizer)  Chest physiotherapy: regular chest physiotherapy  First change of tube The first change of tracheostomy tube is done after 72 hours of surgery . after 72 hours a tract usually form and remains patent . if removed earlier than there is likelihood of soft tissue around tracheostomy collapsing and obstructing the airway Subsequent change of tube  When a metal tube is used –inner tube is removed, cleaned and reinserted without disturbing outer tube, 2 times a day  Outer tube is similarly removed and cleaned and reinserted once a day  When single lumen silastic tube is used – this tube should be removed cleaned and reinserted everyday Deflation of cuffed tube  When a cuffed silastic tube is used, cuff should be deflated every 2 hours for a few seconds or min in order to prevent tracheal injuries- necrosis and subglottic stenosis Principles of Decanulation  Tube size reduced before decanulation  Tube is corked off for increasing periods  Self-ventilating for at least one full night  No further need for tracheal suction  Remove the tube; plug the tracheostomy site

Deviated Nasal Septum Fracture Nasal Bone
Anatomy of Nasal Septum
    Anatomically 3 parts:
1.       Columellar part
2.       Membranous part
3.       Septum proper
DNS
    Aetiology:
1.       Traumatic
2.       Developmental
3.       Racial
4.       Hereditary
    May involve the bony or cartilaginous part
    Classified as:
1.       Spur
2.       Deviation
3.       Dislocation
    Classification of Deformity of Septum.
    Spur.  Sharp angulation  at the junction of vomer below with the septal cartilage  and or ethmoid , due to vertical compression force. # in the septal cartilage produces spur.
2.  Deviation : “C” or “S” , can be on vertical or horizontal  zone, may involve cartilage or bone or both.
3. Dislocation :  lower border of septal cartilage is displaced from its medial position ans projects into one of the nostril.Photo
DNS (spur)
    Sharp projection at the junction of the cartilage and the bony part
DNS ( Deviation)
    Bulging of the either the quadrilateral cartilage or bone.
    ‘C’ or ‘S’ shaped.
DNS ( Dislocation)
  1. The dislocation of the lower border of the septal cartilage from the maxillary crest. OR
  2. Anterior columellar dislocation
  3. Rarely posterior dislocation
Clinical features
  1. Usually asymptomatic
  2. Nasal obstruction
  3. Dry nasal cavity
  4. Recurrent rhinosinusitis
  5. Headache
  6. Epistaxis -rarely
Signs
  1. Decrease nasal patency on the side of the DNS.
  2. On anterior rhinoscopy
-          deviated septum
-          - maybe assoc. compensatory             hypertrophy of the middle or inferior turbinate on the opposite side.
3.     Maybe assoc. wt external nasal deformity.
4.     Investigations:
5.     Clinical diagnosis
Treatment:
       Always Surgical
“As the septum goes, so goes the nose” Correct the septum first
  1.  Treat the chronic sinusitis – Cap. Doxycyclin
  2.  Treat the allergy – antihistamine, steroid spray
Treatment
  1. Only for symptomatic DNS cases.
  2. Surgical modality: Septoplasty OR Submucous resection of the septum (SMR operation)
  3. Inferior turbinate reduction if needed. Collumelloplasty if ant. Collumellar dislocation.
  4. Septoplasty:
    1. Conservative operation where only the deviated part of the septum is removed.
  5. SMR:
    1. Radical operation where most of the bony and the cartilaginous part is excised leaving only ‘L’ shaped portion of the cartilage, superiorly and anteriorly.

    Treatment:
1.       Undisplaced fractures- symptomatic treatment
2.       Simple fractures wt minimal displacement - ext. digital manipulation or intranasal fracture reduction in LA or GA. Either before edema develops or after the edema subsides( in 7-10 days). Delayed ones need rhinoplasty
3.       Complex ones – open surgical procedures. May need involvement of other faculties.

  7. Associated  other allergy
Signs
    1. Boggy, bluish edematous turbinates
    2. Excessive nasal secretions
Sequelae
1.     Regression
2.     Progression to bronchial asthma, ethmoidal polyp
3.     Recurrent sinusitis
4.     Serous ottitis media
Investigations
  1. Nasal smear microscopy- eosinophilia
  2. Skin prick test- 10-30% asymptomatic- positive test
  3. RAST (radioallerosorbent test)
  4. Serum IgE
  5. Nasal provocation test
  6. Scratch test
Treatment
  1. Avoidance of allergens
  2. Medication
    1. Antihistaminics-
                                                               i.      Cetrizine  10-20mg BD
                                                             ii.       Fexofenadine 120-180mg daily
                                                            iii.       loratadine
    1. Topical corticosteroids spray-
                                                               i.      fluticasone,

                                                             ii.      xylometazoline
    1. Oral steriod : for severe symptoms
  1. Desensitization
    1. Blocking IgG antibody that prevent antigen binding to IgE
    2. Effective for seasonal allergy
    3. Drawbacks
                                                               i.      Multiple allergy
                                                             ii.      Difficult to identify exact allergen
                                                            iii.      Series of injections
                                                            iv.      Anaphylaxis
                                                             v.      Recurrence
