Abstract: Objective To evaluate the effect of LCVP applied during the operation of hepatectomy.Methods Sixty patients underwent hepatectomy were enrolled in the study from March 2010 to March 2012 in our hospital which were randomized into LCVP group and normal CVP (NCVP) group by the sealed envelope method. CVP was kept<0.5 kPa during entire procedure of hepatectomy in LCVP group, and the value of CVP and blood pressure were controlled within 10% of the baseline. The same anesthesia, incision and hepatectomy technique and indications of blood transfusion in LCVP group were undertaken as those in NCVP group. Intraoperative CVP, blood pressure, HR and blood routine were recorded. The time of operation, the amount of bleeding, the extent of removed hepatic tissue, the amount of transfused blood products,liver and renal function index, and coagulation function index were detected on the 1st, 3rd and 7th day after operation. Also the supplement of albumin, the rate of postoperation complications and the length of hospital stay and the expense in hospital were recorded.Results ① The general clinical data of patients were similar in the two group (P>0.05). ② The operation time, total bleeding volume, bleeding volume and RBC infusion volume in LCVP group were significantly lower than those in group NCVP (P<0.05). ③ There were no significant difference of postoperative liver and renal function index between the two groups (P>0.05). But the supplement of albumin in LCVP group after operation was significant less than that in NCVP group (P<0.05). ④ There were no significant difference of the postoperative complication, the length of hospital stay and the expense in hospital between the two groups (P>0.05).Conclusions The application of LCVP in hepatectomy cause less blood loss, shorten the length of hospital stay and decrease the expense in hospital, which is beneficial for the postoperative recovery.
