Abstract: Objective:To explore the best method of monitoring during hepatectomy by Meta-analysis.
Methods:From inception to December 13, 2022, The electronic databases of PubMed, Web of Science, Embase, CNKI and the Cochrane Library were searched. Randomized clinical trials reporting outcomes with comparison between stroke volume variation (SVV) guided goal-directed fluid therapy and low central venous pressure (LCVP) guided fluid therapy during liver surgery were included by inclusion and exclusion criteria. The perioperative data was statistically summarized using Review Manager 5.3 software.
Results:A total of 10 randomized clinical trials were included, with a total sample size of 702 cases, including 354 cases (50.4%) in SVV group and 348 cases (49.6%) in LCVP group. The results of Meta-analysis showed that the arterial lactate concentration in the SVV group was significantly lower than that in the LCVP group, with a statistically significant difference between the two groups (weighted mean difference =-0.84 mmol/L, 95%CI: -1.43 mmol/L to -0.25 mmol/L , P=0.005). The reduce intraoperative bleeding and the incidence of total complications without statistically significant differences(all P>0.05). There were no significant differences in surgical field, postoperative biochemical indexes, incidence of serious complications, incidence of postoperative acute renal injury, and length of hospital stay between the two groups(all P>0.05). Conclusion:The use of SVV directed fluid therapy in liver surgery is safe, does not lead to prolonged operative time, increased intraoperative bleeding, or decreased surgical field quality, and significantly reduces intraoperative lactate concentration in patients undergoing hepatectomy.
