Abstract

Background and aims: Continuous CO monitoring has an important role in the management of acute circulatory failure (ACF) in PICU. In this way CO can be measured continuously with a very simple and totally noninvasive process with esCCO by introducing volumetric information to all care levels. This new noninvasive technology using Pulse Wave Transit Time (PWTT), it’s obtained by familiar vital signs parameters of ECG and pulse oximetry. Aims: This study aim to compare CO obtained by esCCO™ to CO obtained by transthoracic echocardiography (TTE) in the management of patients with ACF. Methods: In this prospective study, the assessment CO was obtained by Schimadzu SD 2200 Pro echocardiograph and esCCO™ by a Nihon Kohden, BSM-3763, for each patient had tachycardia, hypotension, oliguria, delayed capillary refilling. Results: Between January and December 2013, 16 ventilated children with ACF, 32 paired CO measurements were obtained: The overall correlation between the CO obtained by esCCO™ and the CO obtained by TTE was r = 0,150. In 09 children less than 3 years and less than15 kg, the correlation was r = 0.0209. In 07 children older than 3 years and older than15kg, the correlation was r = 0.560. Conclusions: esCCO™ is no appropriated method to measure the CO by introducing volumetric information to all care levels. However, this technique remains reliable and reproducible with external calibration of the CO with TTE.
