Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Women will be seen at the Gynaecology clinic where a decision is usually made to perform hysteroscopy. At the time of consenting for the operation women will also be provided information regarding the study. After discussion demographic characteristics of the women consenting to participate will be recorded on the data sheet. This is purely to demonstrate that the two groups were comparable.

Randomisation will be using a computer generated variable block of random numbers. Allocation to treatment or control group will be by opening a sequentially numbered opaque sealed envelope available in theatre and opened towards the end of the procedure. The envelopes and randomization schedule will be prepared by a member of the research team not involved in the care of the woman.

Statistical methods / analysis
Assume that the current incidence of need for additional post-operative analgesia is 20%.For a reduction to 10% with 80 % power and an alpha error of 0.05 we would need 219 women in each group. To allow for attrition we will have a sample size of 225 in each group.

Relative risks with their 95% confidence intervals.
