Emergency cricothyrotomy: a randomised crossover trial comparing the wire-guided and catheter-over-needle techniques.
In a randomised crossover trial, we compared a wire-guided cricothyrotomy technique (Minitrach) with a catheter-over-needle technique (Quicktrach). Performance time, ease of method, accuracy in placement and complication rate were compared. Ten anaesthesiology and 10 ENT residents performed cricothyrotomies with both techniques on prepared pig larynxes. The catheter-over-needle technique was faster than the wire-guided (48 compared to 150 s, p < 0.001) and subjectively easier to perform (VAS-score 2.1 vs. 5.6, p < 0.001). Correct positioning of the cannula could be achieved in 95% and 85%, respectively (NS). There was one complication in the catheter-over-needle group compared to five in the wire-guided group. We conclude that the wire-guided minitracheotomy kit is unsuitable for emergency cricothyrotomies performed by inexperienced practitioners. On the other hand, the catheter-over-needle technique appears to be quick, safe and reliable.
