Abstract

To investigate the relationship between fluid management oriented by critical care ultrasound and prognosis in patients with shock.  Methods  We analyzed the data of a randomized controlled trial called Critical Care Ultrasound Oriented Shock Treatment (CCUSOST) in the Department of Critical Care Medicine, West China Hospital retrospectively. 77 patients in the critical care ultrasound oriented treatment group (experimental group) and 70 patients in the conventionally treated group as control were included in the statistics, to evaluate the relationship between fluid intake and prognosis. Univariate and multivariate logistic regression analyses were used to analyze risk factors for ICU mortality.  Results  The baseline indexes of the patients in the experimental group and the control group were consistent. The ICU mortality of the experimental group was significantly lower than that of the control group (P < 0.05).The fluid intake in the stabilization and de-escalation phases was less than the the control group (P < 0.05). We divided these shock patients into survival group (92 cases) and non-survival (55 cases) according to whether they died in ICU, and the univariate analysis for ICU mortality showed that acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, SOFA score, Lac, hourly urine output, total fluid intake, fluid intake in the salvage and optimization stages, fluid intake in the stabilization and de-escalation stages were significantly different (P < 0.05) between survivers and non-survivers. Multivariete analysis showed that the fluid intake during the salvage and optimization phases, fluid intake in the stabilization and de-escalation phases were independent risk factors for ICU mortality.  Conclusion  Critical care ultrasound oriented shock fluid management could reduce fluid intake of stabilization and de-escalation phases, and improved adverse outcome; whether the fluid intake during stabilization and de-escalation phases, or the fluid intake during the salvage and optimization phases, both were associated with patient prognosis.
