Brief summary

The ANSWER Cricoid Trial is a randomised controlled study to determine whether the use of cricoid pressure is effective in prevention of aspiration during emergency intubations.

Interventions

A force of 30-40N is applied to the patient's cricoid during intubation. This is achieved by the cricoid operator standing on a platform scale and reducing their weight on the scales by 3.060 - 4.075 kg while applying pressure to the patient's cricoid. A data recorder records weight data for later analysis by the researchers. Once successful intubation is confirmed by end-tidal CO2, aspirates will be suctioned from the oropharynx and trachea. the aspirates will be tested for the presence of pe

Once successful intubation is confirmed by end-tidal CO2, aspirates will be suctioned from the oropharynx and trachea. the aspirates will be tested for the presence of pepsin. The patient's records will be reviewd at 28 days to determine whether they were treated for aspiration pneumonitis.
