Study type
Description of intervention(s) / exposure
The randomisation will be to either standard Soltran flush or Methylene Blue flush. If methylene blue is to be used then 0.5mL (5mg) of the methylene blue (50mg/5mL) solution will be diluted in a 1-litre bag of the Soltran solution, with approximately 300mL flushed through the pancreas. The flush will occur via a 'tips cannula' inserted into the arterial Y graft (donor SMA and splenic artery anastomosed to donor internal iliac artery and external iliac artery). Therefore, the overall dose will be ~0.15mL.

NB: International approved name is Methylene Blue manufactured by Phebra

All use will be monitored throughout by the surgical team and the research team will collect data following the procedure. This will be regularly audited throughout the research project to ensure safe practice is being upheld.

Treatment: Drugs
Intervention code [2] 320940 0
Comparator / control treatment
Approximately 300mL of standard soltran flush, which is the Baxter Soltran Kidney Perfusion Solution containing. Each 1000mL contains:
- Potassium Citrate 8.6g, ~80mmol of potassium
- Sodium Citrate 8.2g, ~34mmol of sodium
- Mannitol BP 22.8g
- Magnesium Sulphate 10.0g, ~41mmol of magnesium and ~41mmol of sulphate
NB citrate concentration ~54mmol, the osmolarity is ~466mmol and the pH ~7.1

The Soltran solution will be administered and adherence monitored in the same manner as the Methylene Blue solution

Statistical methods / analysis
Data will be expressed as the mean + standard deviation (SD), median with range, or n (%), as appropriate. Differences among continuous and categorical variables will be examined for statistical significance using the Student t test (or Mann-Whitney’s test) and the chi-squared test (or Fisher’s exact test). Univariate and Multivariate Cox regression will be performed to identify prognostic features for outcomes after pancreas transplantation (including overall survival, graft survival, blood loss, transfusion requirements, etc). The statistically significant level will be p < 0.05, and all analysis will be processed by SPSS (version 23).

Brief summary
For patients that undergo pancreas and kidney transplantation there is a risk of bleeding during and after the operation, one way of reducing this is identifying potential sources of bleeding during the preparation of the organ before we implant it into the patient. One solution called Methylene Blue can highlight these sources of bleeding, therefore we will want to conduct a research project to determine if this will reduce the risk of bleeding.
