Bedside Ultrasound and Noninvasive Cardiac Output Monitoring in Children with Septic Shock: A Retrospective Comparative Study.

No significant differences in vasoactive-inotropic score, resuscitation fluid volume, time to negative fluid balance, or 28-day survival (P > 0.05) were observed between the point-of-care ultrasound and NICaS groups.

(2.7 ± 1.1) L/(min·m²)], with no significant difference on the paired t-test (t = 0.931, P = 0.353).

Pearson correlation analysis indicated a weak correlation between the two methods (r = 0.380, P = 0.546), whereas the Bland-Altman analysis demonstrated good agreement (mean difference: 0.09255, 95% CI - 0.1031 to 0.2882).
