Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The patient will be randomised to one of two groups: an active treatment or placebo control group.
Intervention: After completion of the Craniotomy for a surgical condition, the patients in the active treatment group will be administered subcutaneous single dose of 6 mg sumatriptan for active management of post-operative pain. The site of administration will be chosen by the recovery nurse based on individual factors e.g. arm, abdomen, or leg. Following this pain will be re-assessed at five minute intervals and the usual post-operative prescribed opioid regime will be administered. The usual immediate prescribed post-operative regime involves administration of the intravenous recovery protocol to be used in the recovery area. The medication chosen can be e.g. oxycodone, fentanyl or morphine at the discretion of the treating anaesthetist. If the patient is randomised, but medication is not administered, this will be recorded and data analysed on an intention to treat basis. Adherence with protocol compliance will be monitored through regular monthly study audits.

Treatment: Drugs
Comparator / control treatment
The Placebo Control Group: After Completion of the Craniotomy for a surgical condition, patients randomised to the placebo group will be administered subcutaneous normal saline, in the equivalent volume to the treatment drug volume . Post-Operative pain will be re-assessed at five minute intervals, and the usual prescribed opioid regime will be administered. Adherence with protocol compliance will be monitored.
Control group
Placebo

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be performed in the hospital centrally by the Pharmacy Department. The principal investigators, patients or the nursing staff involved in patient care will not be involved in the process of randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence will be generated centrally by the hospital Pharmacy Department through permuted block randomisation.
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
Intervention assignment
Parallel
Other design features
This is a single centre, double-blinded, randomised, 18 months duration parallel group trial to compare the efficacy of subcutaneous sumatriptan with placebo followed by standard pain protocols.
Phase
Phase 2 / Phase 3
Type of endpoint/s
Statistical methods / analysis
The Intervention arm will be compared against the control for all primary analysis. Descriptive statistics mean (SD) or median (IQR) will be used for continuous variables. Normality of data will be confirmed through graphic histogram plots and specific data tests.
We plan to use the student's T-test to compare the means of different groups for the continuous outcomes of pain scores. Quantitative variables will be compared using the Student's t-test or Mann Whitney U-test to compare the independent means. When indicated, a one-way repeated measures ANOVA will be performed. Categorical variables will be presented as absolute frequencies and percentage. The two groups will be compared using the X² or Fisher exact test. We plan to conduct the two subgroup analysis-based on the anatomical site of surgery as well as the urgency of surgery.
