Our study aimed to evaluate possible relations between the main volumetric indicators for preload and cardiac function, by means of the PiCCO® system and all the data collected from the systematic analysis of anterior-posterior chest X-rays as well as the vascular peduncle and cardio thorax ratio. Patients and Methods: we considered 15 patients in the study and analysed a total of 79 X-rays in elective patients, according to selection criteria. All the patients underwent haemodynamic monitoring, VPW and RCT. Analysis: mean and standard deviation calculations; relationship analysis for the following dual parameters: ITBVI-RCT, ITBVI-VPW, EVLWI-RCT, EVLWI-VPW . Results:The dual values studied demonstrated a moderate relationship between ITBVI-RCT, with R being equal to 0.54 and between EVLWI-RCT. Discussion: Although at a preliminary stage, the most significant data can be seen in the RCT variations, which can be related to interstitial oedema even before the appearance of a critical increase in the alveolar ratio. As far as regards our volumetric data for a more careful analysis of information gathered, we did not observe a relationship between these X-ray tools and the normal volumetric indicators for preload. According to literature and paediatric experience, these instruments present limits that have not yet made it possible to completely replace the correct quantification of extra-vascular water ratio as a response to volumetric increase.
