Abstract

Background Early recognition of septic shock in terms of clinical, macrocirculatory hemodynamic, and microcirculatory laboratory parameters is a fundamental challenge in the emergency room and intensive care unit for early identification, adequate management, prevention of disease progression, and reduction of mortality risk. Objective To evaluate for possible correlations between survival outcomes of post-resuscitation pediatric septic shock patients and parameters of clinical signs, macrocirculatory hemodynamics, as well as microcirculatory laboratory findings. Methods This prospective, study was conducted in the PICU at Saiful Anwar Hospital, Malang, East Java. Inclusion criteria were children diagnosed with septic shock according to the 2005 Surviving Sepsis Campaign (SSC) criteria, aged >30 days-18 years, who were followed up for 72h after resuscitation. The measured variables such as cardiac index (CI), systemic vascular resistance index (SVRI), stroke volume index (SVI) were obtained from ultrasonic cardiac output monitor (USCOM). Blood gas and lactate were obtained from laboratory findings. Heart rate, pulse strength, extremity temperature, mean arterial pressure (MAP), systolic blood pressure (SBP), capillary refill time (CRT), Glasgow coma scale (GCS), and diuretic used were obtained from hemodynamic monitoring tools. Survival outcomes of post-resuscitation pediatric septic shock patients were noted. Results There was a significant correlation between the outcomes of the pediatric septic shock patients 72h after fluid resuscitation and clinical, macrocirculatory hemodynamic, and microcirculatory laboratory parameters. After the 6th hour of observation, strong pulse was predictive of survival, with 88.2% area under the curve (AUC). At the 12th hour of observation, MAP >50th percentile for age was predictive of survival, with 94% AUC. Conclusion For pediatric patients with septic shock, the treatment target in the first 6 hours is to improve strength of pulse, and that in the first 12 hours is to improve MAP >50th percentile for age to limit mortality.

Abstract

Background  Fluid resuscitation with appropriate and adequate amounts is very important in treating critically ill children, so reliable hemodynamic monitoring methods are needed to prevent fluid overload. Contractility index (ICON) is a novel, non-invasive index of left ventricular (LV) function, and contractility related to the electrical cardiometry device (ICON®). ICON® offers a non-invasive hemodynamic monitoring method to assess volume status, but its validity in predicting fluid response in the Indonesian pediatric population remains unknown. Objective To determine the diagnostic performance of ICON-derived parameters, especially change of cardiac output (ΔCO) and change in contractility index (ΔICON), in predicting fluid response, using change of stroke volume (ΔSV)  as a reference standard. Methods A cross-sectional study was conducted in pediatric emergency and intensive care settings. Children aged 1 month to 18 years requiring fluid resuscitation were included. Hemodynamic parameters were measured using ICON® before and after a 10 mL/kg fluid bolus of crystalloid. Fluid responsiveness was defined as a >10% increase in ΔSV. Changes in parameters were analyzed using paired statistical tests. ROC analysis was used to assess the diagnostic accuracy of CO and ICON. Results Sixty-three subjects were analyzed. Significant median changes were observed after fluid bolus administration based on pre- and post-bolus comparison in change of heart rate (ΔHR: –8 bpm, P<0.001), change of systolic blood pressure (ΔSBP: +3 mmHg, P=0.042), change of diastolic blood pressure (ΔDBP: +2 mmHg, P=0.012), change of mean arterial pressure (ΔMAP: +0.67 mmHg, P=0.009). The ROC analysis showed that CO had the highest AUC (0.878), with a cut-off of 5.35%, sensitivity of 78.3%, and specificity of 87.2%. The ICON showed moderate accuracy (AUC 0.757), with a 0.45% cut-off, 69.6% sensitivity, and 71.8% specificity. Conclusion Electrical cardiometry (ICON®) demonstrated measurable changes in objective hemodynamic parameters following fluid bolus administration in critically ill children. Among ICON-derived parameters, a 5.35% increase in CO showed the best predictive performance for fluid responsiveness, while ICON showed moderate diagnostic value. These findings support the clinical utility of electrical cardiometry as a non-invasive tool to guide volume management in pediatric critical care.
