Effect Of Standard Versus Restricted Fluid Therapy Guided By Electric Cardiometry On Tissue Perfuison In Robotic Prostaectomy: A Randomized Controlled Study

What this Trial Is About

Fluid therapy during surgery is an important factor that is related to long term mortality and morbidity and it's directly related to tissue perfusion as well. The main target in any surgery is what is the optimum fluid therapy to maintain the tissue perfusion and the precise balance between hazardous effects of hypervolemia that may cause delayed wound healing due to surgical anastomosis disruption or being hypovolemic that may cause tissue ischemia as acute kidney injury. Fluid management guidance changed from static methods like central venous pressure into dynamic methods like pulse pressure variation (PPV) and stroke volume variation (SVV), which are now the most famous dynamic measures. Electrical cardiometry is a non-invasive cardiac output monitor which uses electrical cardiometry, now a commonly used device, to measure SVV which can be used to guide fluid therapy during surgeries. Now robotic assisted surgery is a common method in preforming many surgeries especially urological, since it's associated with numerous desirable outcomes including shorter post-operative stay and faster return to preoperative function. With considerations related to severe Trendelenburg position and increased intra-abdominal pressure due to pneumo-peritoneum, robotic assisted surgeries are associated with many challenges in anesthesia especially the fluid therapy. Fluid therapy in robotic surgeries is an area with growing research focus that need further exploration while there are established guidelines for fluid management in traditional surgeries, the optimal protocols for robotic surgeries are less well defined, needing more research. We aim at this study to investigate the impact of liberal versus restricted fluid intake on the tissue perfusion reflected by serum lactate \& creatinine clearance, while guiding therapy through electrical cardiometry, to reach optimum fluid protocol in prostatic robotic surgeries.
