Abstract:

Objective To investigate the relationship between ventricular arterial coupling (VAC) and haemodynamics of patients with sepsis and the predictive value for the 28-day prognosis. Methods A total of 164 patients with sepsis were selected and given fluid resuscitation treatment (infusion of 30 mL/kg of crystalloid over 3 h), and changes of VAC[effective aortic elasticity (Ea)/ventricular end-systolic elasticity (Ees)]values and hemodynamic parameters of patients resuscitated for 0 h, 24 h and 72 h were observed. The difference between Ea/Ees for 24 h and 72 h of resuscitation and 0 h was calculated. Pearson method was used to analyze the correlation between Ea/Ees and Δcentral venous pressure (CVP), Δspiratory volume index (SVI) and Δcardiac index (CI). According to the 28-day prognosis, patients were divided into two groups: the survival group (123 cases) and the death group (41 cases). General information was collected in two groups of patients. The predictive values of 24 h ΔEa/Ees and 72 h ΔEa/Ees for 28-day death in sepsis patients were analyzed by multivariate Cox regression models and receiver operating characteristics (ROC) curve. Results The Ea/Ees of 164 patients resuscitated for 24 h and 72 h were lower than those of 0 h, and the Ea/Ees of 72 h was lower than that of 24 h (all P<0.05). CVP, SVI and CI of 164 patients resuscitated for 24 h and 72 h were higher than those of 0 h, and the CVP, SVI and CI of 24 h was higher than that of 72 h (all P< 0.05). The 24 h ΔEa/Ees was significantly lower than that of 72 h ΔEa/Ees (P<0.05), and 24 h ΔCVP, SVI and CI were higher than those of 72 h (P<0.05). There was a negative correlation between 24 h ΔEa/Ees and 24 h ΔCVP, 24 h ΔSVI and 24 h ΔCI (P<0.05). Acute Physiology and Chronic Health Status Score II (APACHE II) ≥20 points, Sequential Organ Failure Score (SOFA)≥10 points, 24 h ΔEa/Ees and 72 h ΔEa/Ees were higher in the death group than those in the survival group (P<0.05). Elevated APACHE II, SOFA, 24 h ΔEa/Ees and 72 h ΔEa/Ees were risk factors affecting the 28-day prognosis of patients with sepsis (P<0.05). The 24-hour ΔEa/Ees and 72-hour ΔEa/Ees were more effective in predicting the 28 d prognosis of patients with sepsis (P<0.05). Conclusion Changes of Ea/Ees can better reflect the haemodynamic changes in sepsis patients in the early stages of treatment and help to predict the 28-day prognosis of sepsis patients.
