Research of goal-directed fluid therapy on laparoscopic liver resection

Objective To explore the application effect of goal-directed fluid therapy(GDFT)on laparoscopic liver resection.Methods From July 2023 to December 2023,48 patients who underwent laparoscopic liver resection were randomly divided into the GDFT group and the CLCVP(controlled low central venous pressure)group.The patients in the GDFT group were guided by stroke volume variability(SVV)during surgery,while those in the CLCVP group were guided by a controlled low central venous pressure technique during fluid replacement surgery.Intraoperative bleeding volume,fluid replacement volume,urine output,liver blood flow obstruction time,postoperative exhaust time,length of hospital stays,and incidence of complications were recorded and compared between the two groups of patients.Results There was a difference between the two groups in terms of crystal fluid,colloid fluid,total fluid volume,and urine volume(P>0.05).However,the bleeding volume in the GDFT group(515.61±246.71)mL was lower than that in the CLCVP group(389.37±187.35)mL(P<0.05);and the blockade time of liver blood flow in the GDFT group(46.33±7.26)min was shorter than that of the CLCVP group(41.84±6.24)min(P<0.05);the postoperative exhaust time of patients in the GDFT group(4.86±1.24)d was shorter than that of patients in the CLCVP group(6.42±1.05)d(P<0.05);the hospitalization days of patients in the GDFT group(9.21±2.15)d were fewer than those in the CLCVP group(11.04±4.29)d(P<0.05).There were no statistically significant differences in the incidence of postoperative complications between the two groups of patients(P>0.05).Conclusion GDFT guided by SVV can stabilize intraoperative hemodynamics in patients undergoing laparoscopic liver resection,reduce intraoperative bleeding,and reduce liver blood flow blockage time.It is safer and more reliable than traditional fluid therapy.
