Davis and colleagues (page 82) describe the results of a randomised controlled trial of the use of double versus single nasal prongs after extubation. Significantly fewer babies (24% versus 37%) “failed” extubation. However, the criteria for failure was not reventilation, but included apnoea; an increase of more than 15% in the inspired oxygen concentration; and respiratory acidosis. The failure rate of single prong extubation was thus much higher than in …
