How often difficult airways occur during heart surgery and creating a tool to predict them

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will enroll adult patients (ASA I–IV) undergoing cardiovascular surgery and collect preoperative airway exam data and intraoperative airway outcomes. Standard bedside scores (for example LEMON, El-Ganzouri, Arne) and intubation findings (Cormack–Lehane, Han mask ventilation score, IDS, VIDIAC where applicable) will be recorded. Cases with known difficult airway, head–neck or upper airway pathology, or aspiration risk are excluded. The investigators will quantify the incidence of difficult airway events and use the collected variables to develop a statistical prediction model specific to the cardiac surgery population.
