Application of ultrasound measurement of inferior vena cava diameter variability in perioperative volume assessment and treatment
Abstract
Objective \nTo investigate the practical value of ultrasound measurement of variability of inferior vena cava diameter in perioperative volume assessment and treatment. \n \n \nMethods \nNinety-six patients undergoing surgical operation in the Second Hospital of Shanxi Medical University from August 2016 to February 2018 were randomly divided into study group and control group, with 48 cases in each group. The control group used central venous pressure monitoring to guide perioperative fluid management, while the study group used central venous pressure monitoring plus ultrasound to measure variability of inferior vena cava diameter to achieve perioperative fluid management. The urine volume per hour, central venous pressure, mean arterial pressure, lactate level and fluid infusion volume were recorded and compared between the two groups before and 6 and 24 hours after treatment. \n \n \nResults \nThere was no significant difference in central venous pressure, mean arterial pressure and lactic acid level between the two groups before treatment (P>0.05). After liquid management in different ways, increases in urine volume, central venous pressure and mean arterial pressure, and decrease in lactic acid level in the study group were superior to those in the control group 6 and 24 hours after treatment (P<0.05). And the amount of fluid infusion in the study group was higher than that in the control group at different time points(P<0.05). \n \n \nConclusions \nCombined application of central venous pressure monitoring and ultrasound in determination of variability of inferior vena cava diameter is helpful to ensure better fluid management in perioperative patients. \n \n \nKey words: \nUltrasound;\xa0Variability of inferior vena cava diameter;\xa0Perioperative period;\xa0Capacity assessment
