ABSTRACT
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 andMethods:
A prospective observational study was conducted in 25 pediatric patients with age < 10 years who underwent elective cardiac surgery. DataAnalysis:
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.Palavras-chave
