Insights
Oral Ring-Adair-Elwyn (RAE) Microcuff® endotracheal tubes are safe and effective for pediatric oral surgery. This study found a low tube exchange rate and minor complications in young children undergoing cleft palate repair.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Medical Devices
Background:
- Preformed cuffed oral endotracheal tubes are standard for pediatric oral surgery.
- Assessing the safety and efficacy of specific tube types is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of oral Ring-Adair-Elwyn (RAE) Microcuff® pediatric endotracheal tubes.
- To determine the endotracheal tube exchange rate and associated complications in young children.
Main Methods:
- Retrospective investigation of endotracheal tube usage.
- Analysis of data from Japanese children under 2 years old undergoing cheiloplasty or palatoplasty.
- Assessment of tube exchange rates and complications.
Main Results:
- The endotracheal tube exchange rate was 3.5%.
- Two cases of unplanned extubation occurred.
- No severe complications were observed during the study period.
Conclusions:
- Oral RAE Microcuff® tubes demonstrate effectiveness and safety in pediatric patients.
- Low tube exchange rates and minimal complications support their use in young children undergoing oral surgery.
Abstract:
Preformed cuffed oral endotracheal tubes are widely used to intubate children undergoing oral surgery. To evaluate the efficacy and safety of oral Ring-Adair-Elwyn (RAE) Microcuff® pediatric endotracheal tubes, we retrospectively investigated the endotracheal tube exchange rate and associated complications in Japanese children younger than 2 years of age undergoing cheiloplasty or palatoplasty. The exchange rate was 3.5%, and although unplanned extubations occurred in 2 patients, no severe complications were observed. Our results suggest that oral RAE Microcuff® tubes are effective and safe for intubating Japanese children younger than 2 years of age, with a low tube exchange rate and minor complications.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
