The Control Low Central Venous Pressure (CLCVP) technique is currently one of the most important techniques to control intraoperative bleeding. It mainly consists of fluid restriction, position adjustment, and the use of vasodilators. However, these measures focus on decreasing CVP by reducing the volume of return blood, and less attention is paid to factors such as pulmonary vascular resistance and cardiac function. Sildenafil, known as Viagra, is currently used to treat erectile dysfunction and pulmonary hypertension in men. Its action inhibits phosphodiesterase-5 (PDE-5) and increases cGMP levels, leading to smooth muscle relaxation and vasodilation. Its pharmacological properties provide potential value for the treatment of many diseases. However, few studies have been conducted both domestically and internationally on the use of sildenafil citrate in liver resection related to CLCVP. This study aims to investigate the influence of preoperative oral administration of Sildenafil Citrate combined with IPM on IBL and surgical results during open or laparoscopic hepatectomy, as well as its safety and feasibility. It is expected to provide an innovative management optimization plan for reducing the bleeding in hepatectomy and to provide empirical support for the potential value of Sildenafil Citrate or Sildenafil-like drugs in improving the safety and quality of perioperative hepatectomy patients.",[77,78,79,80],"Central Venous Pressure","Hepatectomy","Hemodynamics Instability","Sildenafil",[82,78,83,84,85],"Sildenafil Citrate","Laparoscopy","Low central venous pressure","Study protocol","2024-06-25",{"date":88,"type":89},"2024-06-27","ACTUAL",{"date":91,"type":89},"2024-02-01",{"date":93,"type":71},"2024-12-30",{"name":5,"class":6},1]
