Objective: Electrical cardiometry is an impedance-based monitoring technique that provides data on several hemodynamic parameters in a noninvasive way. There is limited information on clinical utility of the application of this technique in neonates., Study Design: In this study, we describe the case of a preterm neonate born at 30 2/7 weeks of gestational age who developed severe systemic infection with fluid refractory septic shock on day 2 of life., Discussion: Electrical cardiometry was used and proved very helpful in real-time guiding the choice and the dosing of the most appropriate inotrope drugs in this patient. In addition, it promptly underlined an abrupt drop of systemic vascular resistances occurring after administration of the first dose of antibiotic, thus warning the attending neonatologist to institute appropriate treatment before the clinical conditions could further worsen., Conclusion: This case report suggests that electrical cardiometry could be a useful tool in assessing, monitoring, and guiding care of neonates who develop severe septic shock. We suggest that electrical cardiometry is a promising approach in the management strategies of such patients that warrants informative clinical trials., Key Points: · Electrical cardiometry was helpful in real-time decision-making.. · Electrical cardiometry reported hemodynamic perturbations before worsening of clinical conditions.. · Electrical cardiometry should be included in the management of critical patients.., Competing Interests: None declared., (Thieme.

Objective: This study aimed to describe the first two cases of electrical cardiometry applied to newborn with hypoplastic left heart syndrome for hemodynamical assessment in the first days of life before surgical correction and see if this can help decision making process in these patients., Study Design: We describe two case series of two full-term newborn with hypoplastic left heart syndrome in the Neonatal Intensive Care Unit, ASST Grande Ospedale Metropolitano Niguarda, between December 2019 and January 2020., Results: Case 1 was persistently hemodynamically stable with prostaglandin E1 infusion at 0.01 mcg/kg/min, showing good capillary refill time, good diuresis, no difference between pre- and postductal values of oxygen saturation or blood pressure. Electrical cardiometry monitoring constantly showed cardiac output values higher than 300 mL/kg/min. Case 2 showed poor clinical condition needing prostaglandin E1 infusion up to 0.05 mcg/kg/min, intubation and septostomy associated with low cardiac output around 190 mL/kg/min. Once cardiac output has begun to rise and reached values constantly over 300 mL/kg/min, clinical condition improved with amelioration in oxygen saturation, diuresis, blood pressure, and blood gas analysis values. She was then extubated and finally clinically stable until surgery with minimal infusion of prostaglandin E1 at 0.01 mcg/kg/min., Conclusion: This case highlights how hemodynamic information provided by electrical cardiometry can be used to supplement the combined data from all monitors and the clinical situation to guide therapy in these newborns waiting surgery., Key Points: · This is the first report of electrical cardiometry (EC) use in newborn with hypoplastic left heart syndrome (HLHS).. · In HLHS patients, it is impossible to measure cardiac output without being invasive.. · EC helps in guiding therapy in HLHS patients in a noninvasive way.., Competing Interests: None declared., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)
