Guiding role of monitoring stroke volume variation on liquid management in gastrointestinal operation

Objective To compare the effects of monitoring stroke volume variation( SVV) and central venous pressure( CVP) on liquid management in gastrointestinal operation and the influence on prognosis. Methods Eighty patients underwent schedule operation of gastrointestinal tract under general anesthesia from March 2012 to December 2012 were enrolled in present study. The patients were randomly divided into two groups( n = 40 each) : SVV group and CVP group. The CVP and radial artery pressure in operation were monitored in CVP group,while the SVV and cardiac output in operation were monitored in SVV group. The blood transfusion volume and infusion fluid volume of pre-,intra- and post-operation,operation time,hospitalization time,exhaust and defecate time,postoperative eating time were recorded and compared. Results Compared with CVP group,the infusion fluid volume and bleeding volume in operation decreased significantly in SVV group( all P 0. 05). There were no significant differences in the total infusion fluid volume three days after operation,the urine volume in operation and postoperative defecate time between two groups( all P 0. 05). The post-operative anus exhaust time,post-operative eating time and hospitalization time in SVV group were all less than those in CVP group( all P 0. 05). The postoperative complications were 9 cases for CVP group,5 cases for SVV group,and there was no significant difference in complications between two groups( P 0. 05). Conclusions Guiding infusion fluid by SVV can decrease infusion fluid volume in operation,shorten hospitalization time,and favor the rehabilitation of operative patients.
