The authors' objective was to determine the association of clinical and laboratory parameters at admission with septic myocardial dysfunction (SMD) in children with septic shock. A chart review of children aged 3 mo-17 y with fluid refractory septic shock who underwent echocardiography within 3 h of admission was undertaken (2015-2017). Univariate followed by multivariate analysis was performed to identify factors associated with SMD. Of the 95 children fulfilling the inclusion criteria, SMD was diagnosed in 44 (46%) children. Children 'with SMD' had longer capillary refill time (CRT), increased lactate, lower platelet count, increased blood urea, and increased alanine aminotransferase (ALT) (p < 0.05 for all) compared to those 'without SMD'. On multivariate analysis, none of these were significant. The mortality rate was higher in those 'with SMD' than 'without SMD' [36% vs. 20% (p = 0.07)]. Prolonged CRT, increased lactate, lower platelet count, increased blood urea and elevated liver enzymes at admission may be associated with SMD in children with septic shock and may warrant early assessment of cardiac function.
