Comparison of noninvasive cardiac output monitoring by electrical cardiometry with transthoracic echocardiography in postoperative paediatric cardiac surgical patients - A prospective observational study.
Aim: The present study was conducted to validate cardiac output (CO) and cardiac index (CI) obtained from electrical cardiometry (EC) ICON ® with transthoracic echocardiography (TTE) in postoperative pediatric cardiac surgical patients.
Materials and methods: A prospective observational study was conducted in 25 pediatric patients with age < 10 years who underwent elective cardiac surgery.
Data analysis: BlandAltman plot was constructed for interchangeability and Polar plot was constructed to know trending ability.
Results: A total of 250 datasets were analyzed. Spearman's correlation coefficient for CO between ICON ® and TTE showed good positive correlation (r = 0.850, 95% confidence interval 0.81 to 0.881, P <.0001). Moderate positive correlation was observed between ICON ® and TTE for CI (r = 0.60, 95% confidence interval 0.515 to 0.674, P <.0001). Linear regression equations for CO and CI between ICON ® and TTE were: y = 0.5230 + 0.8078 X (R2 = 0.6597, P <.001) and y = 1.8350 + 0.5869 X (R2 = 0.3985, P <.001) [y- ICON ®; X - TTE], respectively. BlandAltman plot for CO between ICON ® and TTE showed a bias of 0.3012 with limits of agreement (LOA) being -0.69 to 1.3 and for CI bias was 0.6939 with LOA-2.1 to 3.5. Polar plot analysis showed an angular bias of 8.1750, with radial LOA being -13.74° to 30.08° for CO and angular bias of 6.6931, with radial LOA being -15.69° to 29.07° for CI.
Conclusion: ICON ® monitor-derived parameters are not interchangeable with the values derived from TTE. However, the ICON ® monitor demonstrated a good trending ability for both CO and CI.
期刊介绍：
Annals of Cardiac Anaesthesia (ACA) is the official journal of the Indian Association of Cardiovascular Thoracic Anaesthesiologists. The journal is indexed with PubMed/MEDLINE, Excerpta Medica/EMBASE, IndMed and MedInd. The journal’s full text is online at www.annals.in. With the aim of faster and better dissemination of knowledge, we will be publishing articles ‘Ahead of Print’ immediately on acceptance. In addition, the journal would allow free access (Open Access) to its contents, which is likely to attract more readers and citations to articles published in ACA. Authors do not have to pay for submission, processing or publication of articles in ACA.
