Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will receive 20mL of bupivacaine 0.5% with 1:200,000 adrenaline infiltrated via paracervical block, after induction of general anaesthesia and prior to the initial surgical incision. The intervention is TGA approved.

Five millilitres of the solution will be injected at the 3, 5, 7, and 9 o’clock positions of the cervicovaginal junction at a depth of 10mm as described in the 7th edition of Te Linde’s Operative Gynecology.

The injection will be prepared at the hospital pharmacy. The Study Coordinator will deliver this to the surgeon in theatre. A copy of the randomisation sheet documenting the drug administered will be filed in the patients medical records. The surgeon, patient and anaesthetist will not be aware of which preparation is used.

Comparator / control treatment
The control group will receive a placebo of 20mL of 0.9% sodium chloride via paracervical injection after induction of general anaesthesia and prior to the initial surgical incision. The control group is TGA approved.

Five millilitres of the solution will be injected at the 3, 5, 7, and 9 o’clock positions of the cervicovaginal junction at a depth of 10mm as described in the 7th edition of Te Linde’s Operative Gynecology.

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 allocation sequence will be implemented by using the central telephone (interactive voice response system - IVRS).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Generation of the allocation sequence will be by computer generated random numbers. The allocation sequence will be generated by the NHMRC Clinical Trials Centre, University of Sydney, and implemented by telephone interactive voice response system (IVRS).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
Data will be analysed using IBM SPSS (v. 26 IMB Corp.) with alpha 0.05 considered
statistically significant. Primary outcome QoR-15, and secondary outcomes VAS, time to
mobilisation; time in Patient Anesthetic Care Unit, hospital length in stay and demographic variables age, body mass index will be described using mean, standard deviation and median, with normality assessed using the Shapiro-Wilk test. Categorical secondary variables; opioid use in Patient Anesthetic Care unit, 24 hours and at discharge, and demographic variables co-morbidities will be described using frequency and percent. All variables will be described for total, intervention group and control group baseline. Intervention and control group data will also be described at each time point. A linear mixed model will be used to evaluate the change over the three time points for the primary outcome QoR-15 and secondary outcome VAS with fixed effects intervention group, and controlling for confounders (i.e. body mass index, time to mobilisation, etc.). Two-sided confidence intervals will be reported.

Summary
Brief summary
