A laboratory comparison of two techniques of emergency percutaneous tracheostomy.
This laboratory study was designed to compare the speed of placement of a percutaneous tracheostomy using two common methods and to evaluate any damage caused to the trachea. The same operator who was experienced with both techniques placed 10 percutaneous tracheostomies into a pig tracheal model, five using the Griggs tracheostomy forceps technique and five using the Ciaglia sequential dilatation technique. Placement of the tracheostomy was significantly faster using the Griggs technique (mean 89 s, range 69-105 s) than using the Ciaglia sequential dilator technique (mean 217 s, range 180-267 s). Damage to the posterior wall was noted in four of the tracheas. We concluded that the Griggs technique is rapid and in trained hands may be suitable for emergency airway access. In addition, the pig trachea model is easy to set up and provides a very useful training tool.
