Comparaison de l’impédancemétrie thoracique au doppler œsophagien et à l’analyse du contour de l’onde de pouls dans l’estimation du débit cardiaque au bloc opératoire de chirurgie digestive

Abstract : Introduction: Fluid therapy guided by stroke volume variation decreases morbidity in major digestive surgery. Niccomo is a cardiac output monitoring system using bioimpedancemetry. The objective of the study is to compare the stroke volume and cardiac output value collected by Niccomo to those collected by esophageal doppler and vigileo. Methods: Retrospective single-center analysis for 6 days in July 2019 in the digestive ward of the university hospital of Caen. The primary outcome was the correlation between stroke volume measurements values measured by Niccomo to those measeured by esophageal doppler or Vigileo. Results: 35 pairs of measurements were collected to compare stroke volume and cardiac output between the various techniques. A correlation was found between stroke volumes measured by Niccomo and esophageal doppler with a Pearson correlation coefficient of 0.715 (CI 95% [0.497; 0.848] and p<0.001). A correlation was also found between stroke volumes measured by Niccomo and Vigileo of 0.378 (CI 95% [0.051 ;0.631] and p= 0.025). Conclusion: The trans-thoracic bioimpedancemetry monitoring device Niccomo seems to correlate to those used in practice in surgery at the university hospital of Caen.
