Difficult Airway Incidence in Cardiovascular Surgery and a Prediction Model Development

Condition(s) studied

Study summary

A difficult airway is a clinical condition that occurs when one or more of the components of difficult mask ventilation, difficult laryngoscopy, difficult endotracheal intubation, difficult supraglottic airway device (SGA) placement, and inability to intubate-oxygenate are present. Data concerning incidence of difficult airway in patients undergoing cardiovascular surgery is controversial. Unwanted hemodynamic changes that may occur in patients undergoing cardiovascular surgery, combined with hemodynamic changes caused by underlying cardiac pathologies, may also lead to a physiologically difficult airway situation. Since all these interactions, combined with the hemodynamic changes caused by difficult airway interventions, may lead to catastrophic outcomes, it is vital to predict difficult airway in this patient population.

Eligibility

Primary outcome measure(s)

• Intubation difficulty — 5 minutes after anesthesia induction
  Intubation difficulty is defined with the intubation difficulty scale score and a score greater or equal to 5 is difficult intubation
