Tracheostomy Insertion Techniques

OVERVIEW

Approach to percutaneous dilatational tracheostomy (PDT) procedure:

  • assess for appropriateness of PDT
  • consent
  • fast
  • IV access
  • preoxygenate
  • emergency re-intubation gear
  • standard monitoring (including ETCO2)
  • personnel: surgeon, anaesthesia + bronchoscopist (all with adequate experience or supervision)
  • GA + LA
  • pull ETT back to cords (?LMA use)
  • sterile technique
  • insert tracheostomy

DIFFERENT TECHNIQUES

  • Surgical (not described here)
  • Ciaglia technique (graduated dilatation)
  • Griggs (Portex) technique
  • Translaryngeal approach

CIAGLIA TECHNIQUE (GRADUATED DILATATION)

Method

  • horizontal incision through skin (1.5cm) – traditional Ciaglia Technique was a vertical incision
  • blunt dissection down to tracheal rings
  • needle puncture through first and second tracheal ring
  • once air aspirated insert cannula into trachea -> guidewire
  • graduated dilation
  • tracheostomy insertion

Pros

  • widely used
  • well established
  • low complication rate
  • gradual dilation
  • can insert any size trachy

Cons

  • requires experienced operators
  • loss of PEEP
  • damage to vocal cords with ETT position
  • takes minutes to dilate
  • spray of blood with inspiration
  • damage to posterior wall of trachea (can minimise with bronchoscope)

GRIGGS (PORTEX) TECHNIQUE

Method

  • once guidewire inserted use of guidewire dilating forceps

Pros

  • less steps
  • faster dilation
  • can insert any size trachy

Cons

  • requires experienced operators
  • sterilization of forceps
  • loss of PEEP
  • damage of vocal cords with ETT position
  • more abrupt dilation -> more damage
  • spray of blood with inspiration
  • damage to posterior wall of trachea (minimise with bronchoscope)
  • may want to insert different trachy – wastage

TRNASLARYNGEAL APPROACH

Method

  • ETT tube is pulled back to gain access to the trachea
  • curved cannula introduced into the lumen between the second and third tracheal rings
  • guidewire introduced and advanced in retrograde direction
  • when wire in the pharynx it is grabbed using a Magills forceps
  • patient then intubated with thin ETT
  • tracheal cannula then attached to wire and passed distal to larynx
  • tracheal cannula then pulled through anterior tracheal wall and cut at a predetermined length and rotated 180 degrees by means of an obturator
  • thin ETT removed and tracheostomy cuff inflated

Pros

  • low complication rate
  • safely used in coagulopathy
  • initial tracheal puncture under vision from inside trachea
  • avoids damage to posterior tracheal wall
  • allows V throughout procedure
  • can be done as one person technique

Cons

  • less widely known outside Europ
  • more fiddly
  • needs experienced operator
  • requires lightsource and scope
  • V may be difficult
  • pulling tracheostomy tube through may damage vocal cords
  • only able to insert one size of tube
  • need to use a different technique to change type of tube
