Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Health condition
Health condition(s) or problem(s) studied:
We hypothesize that there will be a higher rate of endotracheal tube leak in uncuffed compared with cuffed tubes, and that the rate of sore throat will be higher in the uncuffed group. 285416 0
We hypothesise that the rate of respiratory complications will be similar between the groups receiving either cuffed or uncuffed endotracheal tubes. 285420 0
We furthermore hypothesise that the loss in lung volume following a standardized recruitment maneouver will be greater in the children intubated with uncuffed ETTs as compared with cuffed ETTs. 285421 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Comparing the use of Cuffed endotracheal tubes (ETT) to Uncuffed endotracheal tubes in the paediatric population.
The tubes will be used during elective surgery requiring invasive airway management. The duration of use will depend on the duration of the procedure in general between 30 and 120 min.
Intervention code [1] 283903 0
Treatment: Devices
Comparator / control treatment
The patients will be randomised to receive either a cuffed or an uncuffed ETT.
The differences between the tubes will be assessed using standardised volume ventilation to identify the leak between the different ETT devices and age groups.

Treatment: Volume ventilation - Tidal volume of 6ml/kg

Baseline tidal volumes & lung compliance prior to and after standardised recruitment manouvers.

Recruitment manoure 10 slow breaths up to 35 cmH2O with a PEEP of 5 cmH2O then Pressure Support Ventilation Peak pressure 10 on PEEP of 5

Incidence of respiratory adverse events (bronchospasm, laryngospasm, coughing, desaturations < 95%, airway obstruction & stridor in both groups.

Documenting incidence of above on CRF

Incidence of sore throat & airway trauma in both groups.
Documentation of blood staining on airway device post removal & completion of validated pain questionnaire by parent /child prior to discharge.
Control group
Active

Outcomes
Primary outcome [1] 286163 0
There will be a higher rate of endotracheal tube leak in uncuffed compared with cuffed tubes.
This will be assessed by calculating the difference between inspiratory and exspiratory tidal volumes.
Timepoint [1] 286163 0
Intraoperativley
Secondary outcome [1] 295283 0
The rate of sore throat will be higher in the uncuffed group.
This will be assessed postoperatively using a VAS scale 0-10.
Timepoint [1] 295283 0
Prior to dischcarge from ward to home

Eligibility
Key inclusion criteria

Minimum age
0 Years
Maximum age
16 Years
Sex
Both males and females

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients will be randomised by computer generated block randomization.

The randomization will be divided into 2 groups: School (> 6 years) and preschool children (< 6 years) with half the children recruited into each group.

Following written informed consent, the participant will be assigned the next available Participant Number in the randomised group. The Participant Number will correspond to a numbered randomisation envelope. The randomisation will be concealed in the closed envelope and will only be opened by the anaesthetist in charge of the patient at induction of anaesthesia. The participant number will be used to identify the patient for the duration of the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The patients will be randomised by computer generated block randomization.
Masking / blinding
