Tracheostomy Procedure: Step-by-Step Approach
Tracheostomy should be performed using a systematic, safety-focused protocol that prioritizes pre-procedure preparation, appropriate sedation with neuromuscular blockade, and strategic apnea intervals to minimize complications and healthcare worker exposure during aerosol-generating moments. 1
Pre-Procedure Preparation
Equipment and medications must be preplanned with a checklist and procedure kits assembled before entering the room. 1
- Avoid bringing carts into the room to reduce decontamination needs 1
- Consider using a disposable bronchoscope if available 1
- Perform universal protocol and timeout outside the room with the procedure team before donning enhanced PPE per institutional protocol 1
- Use ultrasound to assess neck anatomy and identify the optimal point of entry (equipment requires standard decontamination afterward) 1
Patient Preparation and Sedation
Deep sedation and neuromuscular blockers are mandatory to minimize cough and agitation during the procedure. 1
- Before starting, perform a trial of apnea to ensure the patient can tolerate brief periods without ventilation 1
- Withhold ventilation completely during the trial 1
- Discontinue positive end-expiratory pressure (PEEP) 1
- Increase FiO2 to 100% to prevent desaturation for 30 seconds to 1 minute 1
If apnea is not tolerated, reduce ventilatory pressures and respiratory frequency to minimize aerosolization risk, or defer the procedure until ventilatory requirements improve. 1
Critical Apnea Intervals During Percutaneous Dilational Tracheostomy
Apnea must be performed at specific high-risk moments during bronchoscopic-guided percutaneous dilational tracheostomy: 1
- When adding the bronchoscope adaptor to the circuit 1
- Prior to inserting the bronchoscope into the endotracheal tube (ETT) 1
- During ETT pullback with cuff deflation 1
- During insertion of the introducer needle, angiocatheter, dilation, and tracheostomy tube insertion 1
- During bronchoscopic confirmation of placement until closed circuit connection with ventilator is established 1
- During removal of the ETT from the oropharynx 1
Airway Management During the Procedure
Pack the oropharynx and hypopharynx, and place a suction tip in the mouth to reduce aerosolization of oral secretions during ETT pullback. 1
- Place moist gauze or sponge around the guidewire during dilation and around the neck stoma as needed 1
- Ultrasound can be incorporated to avoid bronchoscopic guidance entirely 1
- A modified technique with the bronchoscope placed alongside the ETT while advancing the ETT below the intended stomal entry point may reduce aerosolization 1
Open Tracheostomy Modifications
During open tracheostomy, use apnea during ETT manipulation and prior to incising the anterior tracheal wall. 1
- Avoid or minimize diathermy and suction use as these aerosolize particles 1
- Apply the same apnea intervals as described for percutaneous technique 1
Post-Procedure Management
Place a petrolatum gauze dressing at the fresh stoma site until healing occurs to prevent aerosolization and air leak. 1
- Secure the tracheostomy tube with ties tight enough to prevent dislodgement but loose enough to allow one finger beneath the tie 2
- Maintain cuff pressure between 20-30 cmH2O to prevent tracheal injury while maintaining circuit integrity 2
- Ensure adequate humidification using heat moisture exchangers (HMEs) over large-volume humidifiers 2
Critical Safety Considerations
Healthcare workers face significant infection risk during tracheostomy, with an odds ratio of 4.2 for transmission during aerosol-generating procedures based on SARS outbreak data. 1
- Enhanced PPE (N95 mask, goggles or face shield, surgical gown, and gloves) is essential 1
- The overall complication rate for tracheostomy exceeds 50%, though serious complications are less common 3
- Life-threatening complications include decannulation, obstruction, and hemorrhage 3
- Always maintain an emergency kit at bedside containing: manual resuscitation bag, suction source, suction catheters, replacement tubes (current size and one size smaller), extra ties, shoulder roll, scissors, and emergency contact information 2
