Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Study type
Interventional
Description of intervention(s) / exposure
Participants were randomised to either room temperature or chilled saline and underwent intracapsular tonsillectomy (ICT) +/- adenoidectomy via an Evac 70 Coblation wand, for a total procedure time around 15 minutes. Saline was used as the medium for coblation intraoperatively.

Patients meeting clinical indications for ICT were recruited through the Ear, Nose and Throat (ENT) surgeon's clinic and subsequently surgeries were performed by the same ENT surgeon. Post-operatively patients were provided a questionnaire to assess postoperative pain, bleeding and return to normal activity and this was returned at the follow up appointment two weeks following surgery.

Arm 1: 0.9% Room Temperature Saline with temperature of 22.5°C (comparator)
Arm 2: 0.9% Chilled Saline with temperature of 3.8°C (intervention)

Measured by the operating staff after the conclusion of the procedure
Secondary outcome [2] 439811 0
Post-operative haemorrhage

Return to normal activity
Timepoint [3] 439812 0

Efficacy
Statistical methods / analysis
Sample size was determined using a power analysis based on a clinically significant difference in surgical duration (deemed 2 minutes) and pain (deemed 1 face (i.e. 2 points) on the Wong-Baker Pain Scale). Power analysis for both outcomes indicated that a sample size of 16 patients per study arm would be required to reach 80% power with a two-sided 5% level of significance. Accounting for anticipated participant drop out and loss to follow up, a target population of 42 patients was determined to fulfil both primary outcome measures.

All statistical analysis was completed in RStudio 2024.04.2. Data was found to be nonparametric and Mann Whitney U tests were conducted. A Chi-square test and Fisher’s exact test were used to measure significance in categorical variables
