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)
An independent nurse who is not involved in the liver biopsy or caring for the patient after the procedure will have a randomised list of numbers and the type of drug ( placebo or pethidine) for each number. She will blind the medication by drawing the assigned medication and cover the syringe with a sticker holding the randomisation number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table from a statistic book
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
The sample size was calculated to achieve 80% power to detect a 0.6 (pain score) standard deviation difference with an alpha of 0.05. The two groups were compared by Student t-test or Fisher’s exact test for qualitative variables. A p value of less than 0.05 was considered significant.

Summary
Brief summary
Liver biopsy is an important procedure for the diagnosis and evaluation of liver disease and it can be associated with pain. For years this procedure was performed in Dunedin hospital without Pethidine give prior to the investigation. Two years ago we started giving pethidine immediately before a liver biopsy was performed. This was done to potentially decrease the amount of pain-relief required following the procedure. A recent analysis of our data indicated that this was indeed the case however, an unknown number of patients might have been given Pethidine unnecessarily because they never experienced any pain after the procedure. With this study we would like to assess how effective pre-procedural Pethidine is in controlling pain and anxiety during and after the procedure.
