The Effects of High-volume Hemofiltration by Different Ultrasound Directing on Extra Vascular Lung Water Index in Patients with Septic Shock

Background: We explored the effects of high-volume hemofiltration(HVHF) by different ultrasound direct-ing on the plasma N-terminal pro-B-type natriuretic peptide(NT-Pro-BNP), extra vascular lung water index (EVLWI), liquid net balance quantity and prognosis in patients with septic shock. Methods: Overall, 107 intensive patients with septic shock were enrolled by retrospective analysis from De-partment of Intensive Care Unit (ICU) of the Shandong Provincial Hospital affiliated to Shandong University from 2014-2017. According to HVHF by different ultrasound directing, all the patients were divided into two groups ((ultrasonic cardiac output monitor (USCOM), group A, n=51cases)) and ((critical bedside ultrasound (CBU), group B, n=56cases)). Results: The value of CI in group A had a significant positive correlation with the value of PCCI by the PiC-CO2 monitoring (P＜0.05). The lung ultrasound water B lines in group B also had a significant positive corre-lation with the value of EVLWI by the PiCCO2 monitoring. The cumulative liquid net balance quantity in group B had a more significant elevation than group A after treatment 7th d. The level of EVLWI after treat-ment 48 h and 72 h, the level of plasma NT-Pro-BNP, the levels of P(A-a)DO2,OI and blood lactic after treatment 72 h, and the APACHEⅡ scores and SOFA scores after treatment 7thd were reduced more signifi-cantly in group B than group A (P<0.001). The mortality at 28th day had a more significant decrease in group B than group A. Conclusion: It could decrease the level of NT-Pro-BNP, EVLWI, P(A-a)DO2,which then improves pulmo-nary oxygenation. Consequently, it decreased the APACHEⅡand SOFA scores and improved the 28th sur-vival rate of patients.
