Egypt has a very high prevalence of HCV and a high morbidity and mortality from chronic liver disease, cirrhosis, and hepatocellular carcinoma. Approximately 20% of Egyptian blood donors are anti-HCV positive. Egypt has higher rates of HCV than neighboring countries as well as other countries in the world with comparable socioeconomic conditions and hygienic standards for invasive medical, dental, or paramedical procedures.

Donor safety is on the top of our priorities as a team and it is widely recognized intraopertively during hepatectomy, there are several potential risks during the Perioperative period .

to a conclusion that intraoperative fluid management aids to the reduction of the intraoperative bleeding during the procedure, adequate and guided fluid management is considered one of the important strategies to reduce the blood loss besides of the other anesthetic techniques like hemodilution, normovolemia, cell salvage usage , high Stroke volume variation (SVV) method ,and low CVP technique , the last method is considered the most applicable, simpler, and cost effective technique which could be easier to be performed.
