Filter by:Comparative study on efficacy of haemostatic therapy guided either by standard laboratory coagulation parameters or point-of-care testing in patients undergoing vascular surgical procedures. We investigate the amount of perioperative bleeding and the number of blood product used. Inclusion criteria Patients scheduled for elective and acute open aorta surgery or undergoing acute aorta surgery with minimally invasive techniques and were provided treatment in the operating theatre and/or ICU attached to perioperative care, they must be at least 18 years of age and written informed consent was obtained from the patient or his/her legal representative. Randomisation technique Patients will be randomly assigned to each of two treatment groups using sealed envelopes. In group 1 (G1) haemostasis strategy guided by conventional coagulation tests, while in group 2 (G2) transfusion algorithms guided by point-of-care (POC) tests will be carried out. Sampling techniques and measurements For assessment of monitored parameters shall be used arterial or venous blood depending on the catheter placed preoperatively. In case of the above mentioned vascular surgical procedures, all patients will receive arterial cannula routinely, and, depending on the extension of procedure, as appropriate, a central venous catheter will be inserted as well. Sampling in the patient groups shall be performed as follows: - pre- and postoperative evaluation of standard laboratory parameters in all patients - evaluation of standard laboratory parameters and arterial Astrup test during and after surgery in group 1, if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes - in case of elective surgery: thromboelastometry and arterial Astrup test during and after surgery in group 2 if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes - in case of acute surgery: thromboelastometry and arterial Astrup test before, during and after surgery in group 2 - in case of positive anamnesis, preoperative platelet aggregation test in both groups Besides the above samplings, routine lab tests (blood gas, blood count, sodium (Na), potassium (K), parameters of renal and liver function, clotting and inflammation, lactic acid, blood sugar) will be performed every day as usual during intensive therapy.
This is a global, prospective non-interventional, multi-centre, post-market study of the Vascutek Thoraflex™ Hybrid system in patients with acute thoracic aortic syndrome, subacute/chronic dissection of the aorta and aortic aneurysm.
