Abstract：Objective To study the effect of superior vena cava deformation index (SCI) on volume therapy during liver transplantation. Methods Forty patients who underwent liver transplantation in Hepatobiliary Surgery from January 2017 to January 2018 were collected as study subjects. They were divided into observation group (20 cases) and control group (20 cases). The control group was given conventional central venous pressure (CVP), orterial bleool pressure (ABP) and Swan-Ganz floating catheters to monitor and guide the volume management in the operation. The observation group was given the monitoring of the deformation of the superior vena cava to guide the volume management during the operation. The infusion capacity and operation status of the two groups were observed. Results The mean arterial pressure (MAP), pulmonary artery pressure (PAP), cardiac output (CO), CVP, and SCI values at anhepatic phase 2 min (T3), anhepatic phase 30 min (T4), neohaptic phase 2 min (T5), and neohaptic phase 30 min (T6) of observation group were significantly higher than those of the control group, and the differences were statistically significant (P ＜ 0.05). The input volume of colloidal fluid, crystalloid fluid and the total input volume of fluid of observation group were significantly lower than those of the control group, and the differences were statistically significant(P ＜ 0.05). The recovery time, tracheal catheter time, ICU stay time and hospitalized time of the observation group were significantly shorter than those of the control group, and the differences were statistically significant (P ＜ 0.05). Conclusion It is feasible to monitor the volumetric treatment of liver transplantation by monitoring the SCI in clinical practice. It can effectively maintain the blood volume and tissue perfusion, and reduce the total amount of infusion during surgery. It can promote the recovery of postoperative function more quickly, and it is worth of high clinical value.
