ABSTRACT
Objective:The purpose of this study was to explore new method for evaluating the severity of extravascular lung water in patients after bilateral lung transplantation.Methods:The study was performed in 50 patients after bilateral lung transplantation in our hospital from 2017 to 2018. Picco were implanted during the operation .Two hours after the operation, a doctor monitored the index of EVLWI and PVPI.At the same time, another doctor carried out examination of lung ultrasonography and Calculated the numbers of B line. After ultrasonography, the doctor used ELISA to determine the level of SDC-1.Results:EVLWI were significantly correlated with the number of B-line and the level of SDC-1 ( RS=0.833, RS=0.747, P<0.05), PVPI were significantly correlated with the number of B-line and the level of SDC-1 ( RS=0.738, RS=0.626, P<0.05). Conclusion:The number of B-line and the level of SDC-1 have a good correlation with extravascular lung water. The combination of the two indicators might be used as a reliable index for evaluating the degree of extravascular lung water after bilateral lung transplantation.
