Abstract
Introduction: Hemodynamic monitoring is crucial in managing patients with septic shock. While echocardiography has been increasingly utilized to assess volume status and cardiac function, its impact on patient prognosis remains uncertain. This study aimed to evaluate the effect of echocardiography on outcomes in patients with septic shock.
Methods: This retrospective study utilized data from the Electronic Medical Record system. Septic shock patients were divided into two groups based on echocardiography usage during the onset of septic shock. The primary outcome was 14-day mortality. Secondary outcomes included inotrope use, ventilation-free and norepinephrine-free days, and fluid input. Propensity score matching was employed to reduce baseline differences between groups.
Results: Among the 25 eligible patients, 12 underwent echocardiography evaluation (Echo group), while 13 did not (Control group). The Echo group had a 14-day mortality rate of 33.3% compared to 38.5% in the Control group (P=0.85). Inotrope use was higher in the Echo group (33.3% vs 7.7%, P=0.15). No significant differences were observed in other secondary outcomes. Survival analysis indicated improved 14-day mortality with the use of echocardiography (hazard ratio: 0.83; 95% confidence interval, 0.73–0.95, P=0.005).
Conclusions: Echocardiography use was associated with improved 14-day outcomes in septic shock patients, supporting its use in early hemodynamic assessment.
