COMPLICATIONS
In addition, several other parameters will be collected, which, individually or in combination, can provide insights into the risk–benefit profile of the interventions examined. In case of previously proven non-inferiority as laid out in the primary hypothesis, substantial differences between the procedures regarding accompanying injuries, critical changes in vital parameters during intubation, etc., may hint towards a general advantage of one procedure over the others.Furthermore, perceived task load and the quality of the information flow within the team of care providers (mostly anaesthetists and specialist nurses) shall be assessed using structured, validated questionnaires. The underlying hypothesis is that VAL, through the progress of the intubation process being visible to all involved, simplifies supportive or anticipatory measures by the specialist nursing staff and improves the non-verbal information flow.Ultimately, the primary intention of this study is to determine whether there is a generally recommended instrument that is non-inferior in the uncomplicated airway but possibly causes fewer complications in the (unexpected) difficult airway.
