Study type
Description of intervention(s) / exposure
Patients to receive early administration of prothrombin complex concentrate. It may be administered after surgery has commenced and based on the peritoneal carcinomatosis index (PCI) count, it is considered that the patient is at high risk of massive transfusion. Prothrombinex will be administered at a dose of 20IU/kg ( up to a maximum of 50IU/kg), given intravenously. The dose given will be at the discretion of the physician.

Treatment: Drugs
Comparator / control treatment
Patients will receive usual standard haemostasis management- this includes administration of blood products (FFP, cryoprecipitate) according to laboratory coagulation results.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will be pre-consented for participation in the study prior . As only a proportion of patients will be eligible for randomization (as explained below in study procedures) and in view of the logistic impossibility of real-time consenting, patients will be pre-consented for participation prior to surgery. During surgery, and at the discretion of the surgical and anaesthetic teams, the patient will be determined to be suitable for randomisation based on their anticipated risk of massive transfusion. Eligible participants will be randomised to standard care or early use of Prothrombinex-VF.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation: If the patient is at risk of massive transfusion (as evaluated by the anaesthetist and surgeon), the patient will be randomised to either arm by contacting an independent data manager holding the code. The randomisation code will be one to one using variable block sizes to allocate the patient to either arm.

Brief summary
The purpose of this study is to investigate whether the early use of a blood clotting drug during peritonectomy surgery reduces the amount of bleeding that occurs and so reduces the amount of blood transfusion you may need. Who is it for? You may be eligible to join this study if you are aged 18 years or above and are scheduled to undergo a peritonectomy. Trial details: Peritonectomy surgery is associated with a high risk of bleeding and many patients will require what is known as massive blood transfusion. This typically involves a transfusion of at least 10 units of blood or roughly your whole blood volume. In this research we hope to compare two treatments. Half the participants will receive the standard treatment used in this hospital. This involves the use of blood clotting factors and blood transfusion. In addition patients who have persistently high blood loss are sometimes given a treatment called recombinant factor VIIa. The other half of the participants will receive a product known as Prothrombinex-VF early in the operation when the anaesthetist suspects that there will be high blood loss. Prothrombinex-VF is a commercial product that contains blood clotting factors – these help the blood clot. All other treatment will be the same as usual practice. With this research we hope to be able to show that early use of Prothrombinex-VF reduces the need for blood transfusion and the overall need for blood products such as blood clotting factor preparations.
