NCT04814888

Brief Summary

To determine the correct size of endotracheal tubes (ETT) for endotracheal intubation of pediatric patients is no menial task. Although new methods have been investigated to determine ETT size, and the three-dimensional (3D) printing technology has been successful in the field of surgery, there are not many studies in the field of anesthesia. The purpose of this study is to evaluate the accuracy of a 3D airway model for prediction of the correct ETT size, and compare the results with a conventional age-based formula in pediatric patients.

Outcome Measures

Primary Outcomes (1)

  • ETT size prediction by the printed 3D airway model

    The reliability of ETT size prediction by the printed 3D airway model was compared with the results of the age-based formula.

    during anesthesia induction

Interventions

Two anaesthesiologists unaware of patient's demographic data such as patient's height, weight, and age predicted and recorded ETT size by inserting various sized cuffed-ETTs (MallinckrodtTM Hi-Lo tracheal tube, Covidien, Ireland) to a printed 3D airway model. If the diameter of trachea undersized, air leak around ETT can occur. In that case, we can use that ETT after inflating the pilot balloon with small amount of air. Standard monitoring (non-invasive blood pressure measurement, electrocardiogram, and pulse oximetry) was applied to pediatric patients in the operating room and general anesthesia was induced with ketamine 1 mg/kg and rocuronium 0.6 mg/kg and maintained with sevoflurane. After intubation with a cuffed ETT by a printed 3D airway model was finished, an air leak test was performed by one of three anaesthesiologists dedicated to pediatric cardiac anesthesia.

Sampling MethodNon-Probability Sample
Study Population

We enrolled children under 6 years of age (range 4 days to 61 months) scheduled for surgery for congenital heart disease with chest computed tomography (CT) images including upper airways from September 3, 2019, to March, 16, 2020. Pediatric patients with congenital heart disease were chosen because they usually keep their ETT with mechanical ventilation in the intensive care unit and also have relatively high risk of complication associated with ETT comparing to healthy patients. Therefore, we think it is more important to select appropriate size of ETT in pediatric patients with congenital heart disease.

You may qualify if:

  • children under 6 years of age (range 4 days to 61 months) scheduled for surgery for congenital heart disease with chest computed tomography (CT) images including upper airways

You may not qualify if:

  • pediatric patients with intubation or tracheostomy before general anesthesia due to underlying disease
  • small sized airway with inner diameter \<3.0 mm because of pre-term or low birth weight
  • unstable vital signs during induction
  • history of difficult intubation
  • emergency surgery where printing a 3D airway model in advance was not possible
