Abstract:
Objective To investigate the blood-saving effect of controlled low central venous pressure (CLCVP) in different types of hepatectomy.Methods Ninety ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 37-76 yr,weighing 40-75 kg,undergoing elective hepatectomy,were divided into 6 groups according to the surgical approach and whether CLCVP was used during surgery (n =15 each):CLCVP1-3 groups and nonCLCVP1-3 groups (NCLCVP1-3 groups).The standard hepatectomy,half liver resection and irregular hepatectomy were performed in CLCVP1-3 groups,respectively,with CLCVP.The standard hepatectomy,half liver resection and irregular hepatectomy were performed in NCLCVP1-3 groups,respectively,without CLCVP.In CLCVP1-3 groups,from skin incision to the end of liver resection,CVP was maintained ≤ 5 cm H2 O through adjustment of the position,fluid restriction and iv infusion of nitroglycerin,and norepinephrine was infused simultaneously to maintain mean arterial pressure ≥ 60 mm Hg.In NCLCVP1-3 groups CVP was maintained at 6-12 cm H2O.Intraoperative blood loss and blood transfusion were recorded.Results Compared with NCLCVP1-3 groups,intraoperative blood loss was significantly decreased in CLCVP1-3 groups (P < 0.05).Compared with NCLCVP3 group,the amount of blood transfusion was significantly decreased,the constituent ratio of intraoperative blood loss < 200 ml was increased,and the constituent ratio of intraoperative blood loss > 1000 ml was decreased in group CLCVP3 (P < 0.05).Conclusion CLCVP can decrease the intraoperative blood loss and blood transfusion in patients undergoing irregular hepatectomy.
