Airway Workshop – Advanced Clear Instruction Live Demonstration Hands –On Practice Learn by doing Change tracheostomy tube Resolve blocked tracheostomy Resolve tracheostomy air leak Perform cricothyrotomy

Introduction There are multiple methods and techniques available to successfully complete all the topics presented in this workshop. Some are based on patient request, available equipment or supervising physician’s preference. The goal of this workshop is to correctly demonstrate the most common methods and give participants time for hands on training.

Learning Objectives Learning objectives • Discuss and practice tracheostomy care techniques. • Discuss and practice management for tracheostomy airway obstruction. • Discuss and practice management for tracheostomy airway leaks. • Discuss and practice manament for tracheostomy bleeding. • Discuss indications for and practice cricothyrotomy.

Emergency Cricothyrotomy Catheter

Cricothyrotomy Indications • Temporary emergency airway – When tracheal intubation is not possible. – When face mask or laryngeal mask is unsuccessful. • • Contraindications Inability to identify cricothyroid membrane. Children under 8 years of age. Burn or infection over incision site. Direct trauma obscuring landmarks.

Locate landmark Prep site

One inch vertical incision

Introducer catheter Introduce catheter 45° Aspirate air bubbles to verify location

Flexible guide wire Insert flexible guide wire (Seldinger Technique).

Remove introducer catheter. Anchor flexible guide wire.

Insert Cricothyrotomy catheter Use corkscrew movement to dilate & insert cricothyrotomy catheter.

Technical tip Always visualize proximal end of the wire during airway insertion to prevent inadvertent loss into trachea.

Remove flexible guide wire Connect to ventilator, verify end tidal.

Verify placement A carbon dioxide detector is used to confirm the exchange of air during resuscitation. Attach the CO 2 detector to the cricothyrotomy catheter and begin monitoring CO 2 levels with breath to breath response. A color change between inspiration and expiration helps you verify proper tube placement in seconds. Purple to yellow indicated good air exchange

Tracheostomy Care

Clinical Consensus Statement • Clinical consensus statement (CCS) Aims to improve care for pediatric and adult patient with a tracheostomy tube. • Approaches to tracheostomy care currently inconsistent among clinicians and between different institutions. • The goal is to reduce variations in practice when managing patient with a tracheostomy to minimize complications. • Variations in care and management of patient with a tracheostomy exist between hospitals, inpatient and outpatient facilities, and in the emergency room. • Presently, the current literature does not support the development of clinical practice guidelines but favors a consensus of expertise. Otolaryngol Head Neck Surg. 2013 Jan; 148(1): 6 -20. doi: 10. 1177/0194599812460376. Epub 2012 Sep 18. http: //oto. sagepub. com/subscriptions

Selection of Tracheostomy tubes come in different sizes and different materials. Two types of tracheostomy tubes commonly used are Polyvinyl chloride tracheostomy tubes (Shiley) and Silicone (Bivona). Shiley tubes are slightly flexible and Bivona are the most flexible. Both Shiley and Bivona tubes come standard with a universal adapter for ventilation. In double cannula tubes, the inner cannula is inserted and locked in place after the obturator is removed. The inner cannula can be removed briefly for cleaning. The outer tube is secured to the patient. Single cannula tubes are often used in children and do not have an inner cannula.

Selection of Tracheostomy Fenestrated tracheostomy tubes facilitate speech by allowing better translaryngeal air flow. Some clinicians believe that fenestrated tubes also aid in the clearance of secretions. Other clinicians feel that these tubes promote the development of granulation tissue along the tracheal wall at the level of the fenestrations. Since there is not enough scientific data to support either opinion, it is up to surgeon’s preference. Cuffed tubes have a balloon at the distal end of the tube and allow for mechanical ventilation. Uncuffed tubes are generally preferred in children. Except when requiring ventilation with high pressures, requiring ventilation only at night, or with chronic translaryngeal aspiration.

Provide supplemental oxygen prior to procedure. 5. Check inner cannula – most common cause of obstruction – mucous plug. A. Rinse - inner cannula with warm saline. B. Suction -use saline bullets and suction. Mercado 2013 © 6. Visualize distal end tracheostomy tube with flexible fiberoptic endoscope checking for granulation tissue. Pearl - If unable to clear obstruction may need to change tracheostomy tube. Mercado 2013 ©

Tracheostomy Change Indications: for tracheostomy change include minimizing risk of postoperative infection and granulation tissue formation, verifying formation of a stable tract for ancillary support staff, and downsizing the tracheostomy tube if the patient is clinically improving. Contraindications: Changing a tracheostomy tube too soon after operation (generally < 5 d) before tract has healed adequately, which increases the likelihood of entry into a false passage, Inadequate lighting, exposure, and equipment. Performer inexperience and unavailability of staff versed in airway management. Extremely high ventilator settings, which increases the risk of decannulation. Patient noncooperation without ancillary support

Accidental Decannulation • In an emergency, a dislodged, fresh tracheostomy (within 7 days of tube insertion) should be replaced with the same size or a size smaller tube. • Nasal speculum • Obturator • Risk of false tract/fistula Mercado 2011 ©

Accidental Decannulation • If unable to reintroduce tracheostomy tube into stoma, airway should be secured either via transtracheal or trans-oral intubation.

Complications Although tracheostomy tube changes are routinely performed, the procedure is not without complications. Minimize complications by understanding and practicing procedure as well as anticipating potential problems. In addition to oxygen, pulse oximeter and suction, have basic emergency equipment at bedside, such as a manual ventilator bag, 2 extra tracheostomy tubes (same size as the trach and one smaller), and an obturator The consequences of tracheostomy tube displacement can be dire and can include loss of adequate airway and death. Occasionally, displacement occurs at the time of the first tube change, resulting from creation of a false tract in the pretracheal or peristomal region. This may present insidiously with respiratory failure and subcutaneous emphysema. Confirmation of placement following the procedure with passage of a flexible suction catheter and/or direct visualization with flexible endoscopy will reduce incidence. Resistance met with this maneuver may represent improper placement.

Leaks A low-pressure, high volume cuff is preferred to avoid unnecessary injury to the tracheal mucosa such as tracheal malacia. 1. Check cuff pressure first. 2. Consider changing to a longer tracheostomy tube. 3. Monitor cuff pressure on a regular basis. Shiley® Tube Size Leak Test Volume 10 20 cc 8 17 cc 6 14 cc 4 11 cc

Task: Resolve Leaking Tracheostomy Indications: Leaking tracheostomy tube, poor saturation, etc 1. Explain Procedure. Monitor oxygen saturation. 2. Check cuff pressure. • Defective cuff – ensure cuff has enough air and is working. 3. If cuff is working and still have leak consider • Tracheomalacia. • Fistula 4. Visualize distal end tracheostomy tube with flexible fiberoptic endoscope checking for granulation tissue, etc. 5. Change tracheostomy tube (regular to extra long tracheostomy tube or vice versa).

Bleeding • Local bleeding – Granulation tissue – Superficial bleeding from mucosa – Small vessels • Controlled with – Regular cleaning. – Gelfoam – Chemical cauterization

Bleeding But for anything more than oozing. Must rule out tracheo-innominate artery fistula (TIAF). Causes include; • Low tracheostomy • High innominate artery • Cuff over inflation • Infection

Bleeding • TIAF may cause massive hemorrhage in 0. 7% of tracheotomies. • 2/3 occur in first 3 weeks after tracheostomy • Long-term intubation and ventilation. • Cuffed or uncuffed tube.

Decannulation When the adult patient is in the hospital and; 1. Does not require mechanical ventilation 2. Indication for tracheotomy has resolved 3. Patient tolerates breathing through the tracheotomy tube with the cuff deflated. 4. Breathing with a cuffless #6 Shiley tube is checked (smaller patients, a cuffless #4 Shiley tube is placed) 5. Patient tolerates tracheostomy capped with a red button. 6. If the patient is stable (normal oxygen and CO 2) for 24 – 48 hours with the trach plugged, the tube will be removed by a qualified physician or mid-level provider, and the stoma will be allowed to close. Downsizing, capping and decannulation

Decannulation Downsizing, capping and decannulation

Decannulation When the patient succeeds at decannulation sequence, 1. Wound margins should heal by secondary intention, with initial wound co-apting in 5 to 7 days (unless wound was created with a fenestration technique) 2. New epithelial cells grow across wound in 7 to 10 days. No leak of air from the wound at this time. 3. If wound does not heal, then wound may be closed surgically, by separating trachea from the skin, and closing the wounds in layers. 4. If scar appearance is not acceptable, wound may be closed in a transverse incision across the lower neck with a plastic closure.

Decannulation Mercado 2011 © Assess the patient for associated anomalies of the nervous, respiratory, cardiovascular and gastro-intestinal systems. Re-examine the airway for associated problems: nasal obstruction, adenoid hypertrophy, tonsil hypertrophy, macroglossia, glossoptosis, micrognathia, lingual tonsil hypertrophy, laryngomalacia, glottic web, sub-glottic stenosis, tracheal stenosis or granulation

Clinical Consensus Summary • In the absence of aspiration, tracheostomy tube cuffs should be deflated when the patient no longer requires mechanical ventilation. • A patient initial tracheostomy tube should normally be replaced within 10 -14 days. • The Panel agreed an experienced physician should ideally be present for the first tube change, although there are was recognition that in some facilities, this may not be feasible and thus performed by an experienced advanced practice provider (APP) with immediate physician backup available. • In an emergency, a dislodged, mature tracheostomy tube should be replaced with the same size or a size smaller tracheostomy tube. If those are not available for could not be inserted, then an appropriately sized endotracheal tube should be placed through the wound into the trachea. In a patient in whom a tube could not be replaced, resulting in hypoxia or concern for eventual loss of airway, they should undergo oral tracheal intubation or immediate surgical revision tracheostomy.

Clinical Consensus Summary • Tracheostomy tube should be changed using a clean technique. A sterile technique is not necessary and does not lead to a reduction in impaction. • Plastic tracheostomy tube should be used among pediatric and adult patients for initial tube placement. • Tracheostomy tube ties should be used unless the patient recently underwent local or free flap reconstructive surgery or other major neck surgery. • No patient should be discharged with tracheostomy tube sutured in place. Any suture securing a tracheostomy should be removed during first tube change. • Stoma and tracheostomy tube should be suctioned when there is evidence of visual or audible secretions in the airway, suspected airway obstruction, and whether tube is changed or deflated.

Tracheotomy- Summary 1. Identify source of leaking and bleeding. 2. If unable to safely change tracheostomy at bedside consider revision tracheostomy in OR. 3. Care of the tracheostomy tube and the wound require planning and communication. 4. Do only as much as you have been trained to, feel comfortable doing and is within your scope of practice.
