Condition(s) studied

Endotracheal Tube Wrongly Placed During Anesthetic Procedure

Investigational drug(s) / intervention(s)

UltrasoundCole's Formula

Ultrasound: Using Ultrasound for accuracy of ETT sizing

Cole's Formula: Subglottic diameter in mm x 0.8

Study summary

To compare the accuracy of ultrasound-guided subglottic diameter measurement versus age-based formulas in determining the optimal endotracheal tube (ETT) size in pediatric patients with single ventricle physiology and reducing post-extubation complications.

Healthy volunteers
No
Inclusion Criteria: * Pediatric patients (3 months to 8 years) * Patients with single ventricle physiology * Scheduled for Glenn or Fontan surgery or cardiac catheterization * Patients with Glenn or Fontan shunt scheduled for surgery Exclusion Criteria: * Refusal of legal guardians * Emergency surgery * Patients with tracheostomy tubes * Recent or active upper respiratory tract infection * Airway anomalies (e.g. Pierre Robin, Treacher Collins) * ICU stay due to complications other than that of airway

Primary outcome measure(s)

  • Accuracy of ETT size selection — During endotracheal intubation, immediately after induction of anesthesia and neuromuscular blockade (within 10 minutes after induction)
    Accuracy of endotracheal tube size selection measured by the number of ETT attempts required to achieve an appropriate leak test and successful airway placement.
