Perioperative Protocol Goal Directed Therapy in Kidney Transplantation: Fluid Therapy Optimization and Impact on Postoperative Complications.

In literature there is a huge amount of works demonstrating the direct correlation between volemic overload or fluid deficit and hypoperfusion and the increase in the rate of major postoperative complications in patients with high cardiovascular risk and chronic renal failure candidate to kidney transplantation from cadaver. It is also widely demonstrated that in certain populations with high surgical and post-operative complications risk, the adoption of targeted haemodynamic and clinical-therapeutic management protocols is indicated. The current trend is therefore to guarantee greater precision in the intraoperative management of patients undergoing kidney transplantation from cadaver by using a specific protocol that can be framed in the recent and innovative concept of Perioperative Gold Directed Therapy (PGDT), resulting from the adoption of an advanced minimally invasive hemodynamic monitoring technology with a special sensor called FloTrac (Edwards Lifesciences), already extensively tested in an extensive case series of high perioperative risk patients underwent to major abdominal surgery, major vascular surgery, major orthopedic surgery and cardio-thoracic surgery. In the present study there will be enrolled all patients who are candidates for kidney transplant from cadaver at the University Hospital "G. Rodolico" of Catania that meet the inclusion criteria of the study and will give their informed consent to participation. The enrolled patients will be monitored for a maximum period of 7 days from transplantation. As control group there will be considered an historical cohort of patients who underwent kidney transplantation from cadaver in 2015, in which a PGDT protocol was not used, but a common hemodynamic monitoring, based on parameters such as central venous pressure and / or invasive arterial pressure, was performed according to the international guidelines.
