Indications!• To maintain the airway• To protect the airway• For bronchial toilet• For weaning from IPPV
Cautions & Contraindications • Difficult anatomy • Moderate coagulopathy • Proximity to site of recent surgery or trauma • Localised infection • Severe gas exchange problemsPatients generally requiring an emergency trachy don’t have the luxury of having theseconditions corrected before hand!
Patient Benefits!• Less risk of long-term airway damage.• Patient comfort – no tube in mouth!• Some can eat & talk!• Tube more secure some patients can mobilise.
Surgical• Normally done electively (ICU,OT)• Can be done @ bedside (emergently)• 3-5cm incision 1 cm below cricoid• Done under general or local anaesthetic.Procedure – Dissection down to the trachea, surgical incision is made in “T” shape, between 2nd& 3 rd tracheal rings.
Percutaneous• Done in emergency circumstance where theater is not an option.Procedure: – No surgical incision required- opening is made via percutaneous “stab” into trachea.
Emergency• Emergency circumstance requiring extreme measure to secure the airway• Cricothroidotomy• Procedure: – Percutaneous stab into trachea to provide an opening and allow ventilation. – Scalpel-bougie, Scalpel –finger, Ball point pen!
The Types1. Cuffed and uncuffed2. Fenestrated and unfenestrated3. Those with inner cannulas and those without
Cuffed Vs Uncuffed• Used initially • Used long term• Reduces aspiration, • Pt needs reasonable foreign matter in bulbar function to clear airway. own secretions• Prevents air escape in MV.• Cuff pressure 15- 25mmHg.• Use in emergencies!
FenestratedFenestrated:• Has pre-cut opening in posterior aspect of tube.• Facilitates air entry through the tube and allows speech.• Has 2 tube’s one that allows suctioning, eating & during sleep, the other allows talking.
Inner cannula• Have an inner tube that allows removal if becomes obstructed to allow removal & cleaning• Reduce potentially life threatening complications.• Increases the WOB.
When to Suction?• Course breath sounds (crackles)• Noisy Breathing• ∧or ∨ resp rate• ∨ Sp02• Copious secretions• Pt attempting but unable to cough or clear secretions• Distressed or agitation
Factors that can Contribute to Emergencies!• Overproduction of sputum• Coughing• Irritation of the trachea• Undue movement of the tube• Multiple suctioning attempts• Dry, hardened secretions –sputum plug• Cuff integrity compromised• Vomitus or aspiration of stomach contents
The Approach• Is the tracheostomy tube displaced or obstructed?• Is the tube cuffed or uncuffed?• How old is the tract?• What is the size of the tube?• Why was the tube placed?
Case 1• 28 male P1 ambulance• Known Quad with long term trachy.• P/C: ?Blocked trachy• 0/A: Cyanosed lips, not moving air.• V/S: Spo2 70%, HR 145, GCS 8What do you do?
Blocked Trachy• Apply O2 to mouth and trachy• Try Suctioning – remove inner cannula.• Partial occlusion use saline Nebs, humidification, suctioning.• If fail try BVM – push down occlusion into lungs.• Change trachy tube or re-intubate!
Case 2• 74 male known throat ca• Long term trachy - fenestrated• P/C Trachy fallen out• O/A: Mild resp distress, unable to talk/• V/S: RR 22, Spo2 90%, Bp 138/84,• What do you do?
The Dislodged Trachy• Completely dislodged vs. false passage!• Most prevalent in newly created trachy!• Occurs with forceful coughing and poorly secured trachy.
The Dislodged Trachy• Replace with same size or smaller.• May need trachy dilators and bougie to assist.• Trachy set not available use small ETT.• Check correct placement – pass suction catheter, Etco2, clinical improvement, auscultation, CXR.• R/F to ENT.
Take Home Points• Trachy emergencies generally uncommon!• Have an approach!• Know how to suction!• Provide O2 to trachy and to mouth if distressed!• Always change to cuffed tube in emergencies!• Same size or smaller or just use an ETT!
